16 g of copper was heated from 20°C to 85°C. How much energy was used to heat Cu? (Specific heat capacity of Cu is 0. 385 J/g °C)

Answers

The amount of energy used to heat 16 g of copper from 20°C to 85°C is 404.8 J.

The quantity of energy that is moved from one object or system to another as a result of a temperature differential is referred to as the amount of heat transferred. It can have the following formula:

Q = m x c x ΔT

where:

Q = amount of heat energy transferred,

m = mass of the substance,

c = specific heat capacity of the substance, and

ΔT = change in temperature.

Firstly, we would determine the change in temperature:

ΔT = T₂ - T₁

= 85°C - 20°C

= 65°C

Next, we can calculate the amount of heat transferred using the above values:

Q = m x c x ΔT

Q = 16 g x 0.385 J/g °C x 65°C

Q = 404.8 J

when deionized water was added to the blue solution, the equilibrium shifted, as evidenced by the color change. how did this stress change the value of the equilibrium constant, k? justify your answer.

Answers

When deionized water was added to the blue solution, the equilibrium shifted, as evidenced by the color change. The value of the equilibrium constant, k was changed by the addition of more reactants.

When a strong acid is added to a prepared buffer solution, the pH change is minimal due to the presence of a weak acid and its conjugate base in the buffer. These components work together to neutralize the added acid, maintaining the pH within a certain range. In contrast, when the strong acid is mixed with deionized water, the pH change is more significant because there are no buffering agents to neutralize the acid.

Based on the results obtained, the prepared buffer solution effectively resisted pH changes when minimal amounts of acid or base were mixed into the solution. A buffer solution is a solution that is capable of resisting changes in pH when small amounts of acid or base are added to it. A buffer solution typically consists of a weak acid and its conjugate base or a weak base and its conjugate acid.

What is the final temperature after 279 joules is absorbed by 36.0 g of water at 51.0 C? Need help.

Answers

After absorbing 279 J of heat, the water's final  temperature is 56.1°C.

How to calculate final temperature?

To solve this problem, use the equation:

q = mcΔT

where q = heat absorbed by the water (in joules), m = mass of water (in grams), c = specific heat capacity of water (4.184 J/g°C), and ΔT = change in temperature (in °C).

First, calculate the initial heat (q₁) absorbed by the water:

q₁ = mcΔT

q₁ = 36.0 g x 4.184 J/g°C x (51.0°C - 0°C)

q₁ = 7,168.128 J

So, initially, the water absorbed 7,168.128 J of heat. Now, to find the final temperature, add the additional heat absorbed (279 J) to the initial heat (q₁), and solve for the final temperature (T f):

q₁ + q₂ = mcΔT  f

T  f = (q₁ + q₂)/(m×c)

Plugging in the values:

T  f = (7,168.128 J + 279 J)/(36.0 g x 4.184 J/g°C)

T  f = 56.1°C

Therefore, the final temperature of the water is 56.1°C after absorbing 279 J of heat.

Through the tubuloglomerular feedback mechanism, how would an increase in filtrate NaCl concentration affect afferent arteriole diameter?

Answers

Through the tubuloglomerular feedback mechanism, an increase in filtrate NaCl concentration would lead to a decrease in the afferent arteriole diameter.

Here's a step-by-step explanation:
1. An increase in filtrate NaCl concentration indicates a high filtration rate or low reabsorption rate.
2. High NaCl concentration in the filtrate reaches the macula densa cells, which are part of the tubuloglomerular feedback system located in the distal tubule.
3. Macula densa cells detect the high NaCl concentration and release chemical signals (such as adenosine) in response.
4. These chemical signals cause the smooth muscle cells in the afferent arteriole to constrict, leading to a decrease in the afferent arteriole diameter.
5. The decreased diameter of the afferent arteriole reduces blood flow into the glomerulus, thereby lowering the glomerular filtration rate (GFR) and allowing more time for NaCl reabsorption in the nephron.
In summary, the tubuloglomerular feedback mechanism helps maintain a constant GFR by detecting changes in filtrate NaCl concentration and adjusting the afferent arteriole diameter accordingly.

If sulfur dioxide concentrations emitted from a volcano increase from less than one part per million (ppm) to 4ppm, is the volcano more or less likely to occur?

Answers

Answer:

Please help me too by marking me the brainliest.

Explanation:

The concentration of sulfur dioxide emitted from a volcano does not indicate whether the volcano is more or less likely to occur. Sulfur dioxide is a gas that is often released from volcanoes, and its concentration in the atmosphere can be used to monitor volcanic activity. However, the concentration of sulfur dioxide alone cannot determine whether a volcano is more or less likely to occur.

Volcanic activity is influenced by a complex set of factors, including the type of volcano, the magma composition, the pressure within the volcano, and other geological factors. Changes in the concentration of sulfur dioxide may indicate changes in the activity level of a volcano, but they are not a direct measure of the likelihood of an eruption.

Therefore, we cannot determine whether the volcano is more or less likely to occur based solely on an increase in sulfur dioxide concentrations from less than one part per million to 4ppm.

MY OPINION

if the sulfur concentration from the volcano increased this much supposing it happened in a single day, then it is more likely to occur.

What is the molar solubility of zinc oxalate ( ZnC2O4 ) in water? The solubility-product constant for ZnC2O4 is 2.7 × 10^-8 at 25°C.
A) 1.4 × 10^-8
B) 5.4 × 10^-8
C) 7.57
D) 2.3 × 10^-4
E) 1.6 × 10^-4

Answers

The molar solubility of zinc oxalate in water is 1.4 × 10⁻⁸ mol/L or 1.4 × 10⁻³ M.

To find the molar solubility of zinc oxalate in water, we first need to write the solubility equilibrium expression:

ZnC₂O₄(s) ⇌ Zn2+(aq) + 2C₂O₄2-(aq)

The solubility-product constant (Ksp) is given as 2.7 × 10⁻⁸ at 25°C, which means:

Ksp = [Zn2+][C₂O₄2-]²

Since the molar solubility of zinc oxalate is represented by "x", we can set up an ICE table:

ZnC₂O₄s) ⇌ Zn²⁺(aq) + 2C₂O₄2-(aq)
I       1          0            0
C     -x         +x           +2x
E    1-x         x            2x

Substituting the equilibrium concentrations into the Ksp expression:

Ksp = [Zn2+][C₂O₄-]²
2.7 × 10⁻⁸ = x(2x)²
2.7 × 10⁻⁸ = 4x³
x³ = 6.75 × 10⁻⁹
x = 1.4 × 10⁻³ M

Therefore, the molar solubility of zinc oxalate in water is 1.4 × 10⁻³ M or 1.4 × 10⁻⁸ mol/L. The answer is (A) 1.4 × 10⁻⁸.

How does the standard entropy of a substance depend on its molecular complexity?

Answers

The standard entropy of a substance generally increases with its molecular complexity. This is because as the number of atoms and bonds in a molecule increases, there are more ways for the molecule to vibrate and rotate, which results in a greater number of possible states or arrangements for the molecule.

These additional states contribute to a higher entropy value, indicating that the substance is more disordered and has a greater degree of randomness. However, there are exceptions to this trend, as certain molecular structures may restrict the number of possible states and limit entropy despite having a high degree of complexity.

The standard entropy of a substance depends on its molecular complexity because more complex molecules have a greater number of possible arrangements and motions, leading to higher entropy. In general, as molecular complexity increases, the standard entropy of a substance also increases. This is due to the increased number of vibrational, rotational, and translational degrees of freedom in complex molecules, which result in more microstates and thus higher entropy.

what is the density in g/l of co at 1140 torr and 75.0 °c?

Answers

The density of CO gas at 1140 torr and 75.0 °C is 1.53 g/L.

How to calculate the density of CO gas at 1140 torr and 75.0 °C?

To calculate the density of CO gas at 1140 torr and 75.0 °C, we can use the ideal gas law:

PV = nRT

where P is the pressure in atmospheres (atm), V is the volume in liters (L), n is the number of moles of gas, R is the ideal gas constant (0.08206 L·atm/mol·K), and T is the temperature in Kelvin (K).

First, we need to convert the given pressure of 1140 torr to atmospheres:

1 atm = 760 torr

1140 torr ÷ 760 torr/atm = 1.50 atm

Next, we need to convert the given temperature of 75.0 °C to Kelvin:

T (K) = T (°C) + 273.15

T (K) = 75.0 °C + 273.15 = 348.15 K

Now we can rearrange the ideal gas law to solve for the density of CO:

n/V = P/RT

To find the density, we need to solve for n/V, which is the number of moles of CO per liter of gas:

n/V = P/RT = (1.50 atm) / (0.08206 L·atm/mol·K x 348.15 K) = 0.0544 mol/L

Finally, we can calculate the density of CO in g/L using its molar mass:

Molar mass of CO = 12.01 g/mol + 15.99 g/mol = 28.00 g/mol

Density of CO = (0.0544 mol/L) x (28.00 g/mol) = 1.53 g/L

Therefore, the density of CO gas at 1140 torr and 75.0 °C is 1.53 g/L.

Enantiomers are molecules that are mirror images but they are not superimposable. They are diastereomers if they are not superimposable and are not mirror images.

X = 2ⁿ, where n is the number of stereogenic atoms in the molecule, is the formula for determining the maximum number of stereoisomers. For instance if a molecule has 2 stereocenters, from X = 2ⁿ  four stereoisomers must be present. If similarly a molecule has 3 stereocenters, using the same formula a maximum of eight stereoisomers must be possible.

a solution is prepared by dissolving 15.0 g of nh3 in 250.0 g of water. the density of the resulting solution is 0.974 g/ml. what is the mole fraction of nh3 in the solution?

Answers

The mole fraction of NH₃ in the solution is 0.076. The mole fraction is a way of expressing the concentration of a component in a solution. It is defined as the number of moles of a particular component divided by the total number of moles in the solution.

To determine the mole fraction of  NH₃ in the solution, we need to first calculate the total mass of the solution.

Total mass of solution = mass of  NH₃ + mass of water

Total mass of solution = 15.0g + 250g

Total mass of solution = 265.0g

Next, we can use the density of the solution to calculate its volume:

Density = mass/volume

0.974 g/ml = 265.0g/volume

Volume = 272.11 ml

Now we can use the mass of  NH₃ and the total volume of the solution to calculate the mole fraction of  NH₃:

Mole fraction of  NH₃= moles of  NH₃/total moles in solution

To find the moles of  NH₃, we need to first convert the mass of  NH₃ to moles using its molar mass:

Molar mass of  NH₃ = 14.01 g/mol

Moles of  NH₃= 15.0g / 14.01 g/mol

Moles of  NH₃= 1.07 mol

To find the total moles in the solution, we need to use the density and the molar volume of water (which is 18.02 mL/mol at room temperature and pressure):

Volume of water = total volume - volume of  NH₃

Volume of water = 272.11 ml - (15.0g / 1.00 g/ml)

Volume of water = 257.11 ml

Total moles in solution = (257.11 ml / 1000 ml/L) * (1 L/1000 ml) * (1 mol/18.02 L)

Total moles in solution = 0.014 mol

Now we can calculate the mole fraction of  NH₃:

Mole fraction of  NH₃= 1.07 mol / 0.014 mol

Mole fraction of  NH₃= 0.076

Therefore, the mole fraction of  NH₃ in the solution is 0.076.

calculate the pH and pOH when [H+] = .025 M

Answers

The pH of a solution is a measure of the activity of hydrogen ions (H+) in the solution. pOH is a measure of the activity of hydroxide ions (OH-) in a solution.

To calculate pH and pOH, when [H+] = 0.025 M, we can use the equation pH + pOH = 14. First, we calculate pH. Since [H+] is given, we can calculate pH directly from [H+] using the equation pH = -log[H+]. Plugging in [H+] = 0.025 M gives pH = -log(.025) = 2.6.

Next, we can calculate the pOH. Since pH + pOH = 14, we can calculate pOH by subtracting pH from 14. Plugging in pH = 2.6 gives pOH = 14 - 2.6 = 11.4. Therefore, the pH and pOH of a solution with [H+] = 0.025 M are 2.6 and 11.4, respectively.

Intense heat and pressure can change igneous and sedimentary rock into metamorphic rock. Metamorphic rock is formed when pre-existing rocks, either igneous or sedimentary, are subjected to extreme heat and pressure, causing physical and chemical changes in the rock's minerals and texture.

The process of metamorphism occurs deep beneath the Earth's surface, where temperatures and pressures are high enough to alter the minerals and texture of pre-existing rocks. Heat and pressure cause the minerals in the rock to recrystallize, meaning they form new crystals that are more tightly packed together.
