Find q when 22.0 g of water is heated from 29.0°C to 100.0°C.
Answer:
6530 J
Explanation:
To find the value of "Q", you need to use the following equation:
Q = mcΔT
In this equation,
-----> Q = energy/heat (J)
-----> m = mass (g)
-----> c = specific heat capacity (J/g°C)
-----> ΔT = change in temperature (°C)
The specific heat capacity of water is 4.182 J/g°C. You can plug the given values into the equation and solve for "Q". The final answer should have 3 significant figures because the lowest number of sig figs among the given values is 3.
Q = ? J c = 4.182 J/g°C
m = 22.0 g ΔT = 100.0 °C - 29.0 °C = 71.0 °C
Q = mcΔT
Q = (22.0 g)(4.182 J/g°C)(71.0 °C)
Q = 6530 J
Approximately 6461.9 joules of heat are required to heat 22.0 g of water from 29.0°C to 100.0°C.
Given:
mass of water, m = 22.0 g
Specific heat capacity of water, c = 4.184 J/g°C
Change in temperature, ΔT= 100.0°C - 29.0°C = 71.0°C
The formula for the heat absorbed or released during a temperature change:
q = m × c ×ΔT
where:
q = heat (in joules, J)
m = mass of the substance (in grams, g)
c = specific heat capacity of the substance (in J/g°C)
ΔT = change in temperature (in °C)
For water, the specific heat capacity is approximately 4.184 J/g°C.
Putting the values into the formula and calculating q:
q = 22.0 g × 4.184 J/g°C ×71.0°C
q ≈ 6461.9 J
Thus, approximately 6461.928 joules of heat are required.

A sample of nitrogen gas has a volume of 3.0 L at 25 degrees Celsius and 720 torr. What would the volume be at STP? (Hint: This is a combined gas law question).
Answer:
2.60 L
Explanation:
To find the new volume, you need to use the Combined Gas Law:
[tex]\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}[/tex]
In this equation, "P₁", "V₁", and "T₁" represent the initial pressure, volume, and temperature. "P₂", "V₂", and "T₂" represent the final pressure. volume, and temperature.
At STP, the pressure is 1.0 atm and the temperature is 273 K. Before you can plug the values into the equation, you need to convert pressure from torr to atm and the temperature from Celsius to Kelvin.
P₁ = 720 torr / 760 = 0.947 atm P₂ = 1.0 atm
V₁ = 3.0 L V₂ = ? L
T₁ = 25 °C + 273 = 298 K T₂ = 273 K
[tex]\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}[/tex] <----- Combined Gas Law
[tex]\frac{(0.947atm)(3.0L)}{298K}=\frac{(1.0atm)V_2}{273K}[/tex] <----- Insert values
[tex]\frac{2.84}{298K}=\frac{(1.0atm)V_2}{273K}[/tex] <----- Multiply 0.947 and 3.0

How do scientists believe that chloroplasts got into photosynthetic cells?
Let's see what I can come up with here. So chloroplasts are made up of several separate sections. They have the stroma (the liquid in which everything is contained) and the grana (plural of granum and is a stack of thylakoids). Chlorophyll is found in thylakoids.
The chlorophyll absorbs light (not green light since that is what is reflected to our eyes). Light energy is utilized to split water into hydrogen ions, electrons, and oxygen gas. With these ions and electrons, the electron transport chain, with the assistance of enzymes, produces ATP and NADPH. In all living cells, ATP is the primary source of energy. Because light is required to split water, this step of photosynthesis is known as the "light reaction."
The ATP and NADPH are transported into the stroma, where the "dark reaction" can take place. And, despite the name, it does not occur at night since our energy source does not store well. You've probably heard of the Calvin Cycle. The Calvin Cycle basically uses water, CO2, and the energy from earlier to generate carbohydrates, which are then stored in various ways. Glucose is the most well-known monosaccharide, although there are others, as well as countless polysaccharides such as cellulose and starch.

Answer:
The volume of the gas sample at standard pressure is 819.5ml
Explanation:
Solution Given:
let volume be V and temperature be T and pressure be P.
[tex] V_1=250ml[/tex]
[tex] V_2=?[/tex]
[tex] P_{total}=735 mmhg[/tex]
1 torr= 1 mmhg
42.2 torr=42.2 mmhg
so,
[tex] P_{water}=42.2mmhg[/tex]
[tex] T_1=35°C=35+273=308 K[/tex]
Now
firstly we need to find the pressure due to gas along by subtracting the vapor pressure of water.
[tex] P_{gas}=P_{total}-P_{water} [/tex]
=735-42.2=692.8 mmhg
Now
By using combined gas law equation:
[tex]\frac{P_1*V_1}{T_1} =\frac{P_2*V_2}{T_2}[/tex]
[tex]V_2=\frac{P_1*}{P_2}*\frac{T_2}{T_1} *V_1[/tex]

Assuming ideal solution behavior, what is the boiling point of a solution of 115.0 g of nonvolatile sucrose (table sugar), C₁₂H₂₂O₁₁ (342.300 g/mol), in 350.0 g of water (Kb = 0.512 °C m⁻¹; boiling point = 100.0 °C)?
The boiling point of the solution will be 100.97 ° C.
[tex]T_f[/tex], pure water = 0.00 ° Celsius.
[tex]T_b[/tex] , pure water = 100° Celcius
[tex]K_b[/tex] = 0.512 C kg/mol
[tex]K_f[/tex] = -1.86 C kg/mol.
Given,
[tex]K_b = \frac{0.512 C kg}{mol}[/tex]
[tex]m = \frac{115g \frac{mol }{342.300g} }{0.35 kg}[/tex]
m = 0.95
i = 2 ( assuming no ion pairing)
Now, recall,
Δ[tex]T_b[/tex] =[tex]iK_bm[/tex]
Hence,
Δ[tex]T_b[/tex] = [tex]iK_bm[/tex]
= 2 × 0.512 × 0.95
= 0.97 °C
Therefore, the boiling point of the solution will be 100.97 °C.

is there any methods to determine number of water crystallization?
Answer:
In the formula, we can see that for each unit of copper(II) sulfate, there are five molecules of water associated with it. One way to determine the amount of water of crystallization in a hydrated salt is to use volatilization gravimetry
What is the specific heat of a substance if 1500 J are required to raise the temperature of a 300.0 g sample from 25°C to 40°C?
Group of answer choices
A. 33 J/g°C
B. 333 J/g°C
C. 4.18 J/g°C
D. .33 J/g°C
Answer:
D.) 0.33 J/g°C
Explanation:
To find the specific heat, you need to use the following equation:
Q = mcΔT
In this equation,
-----> Q = energy (J)
-----> m = mass (g)
-----> c = specific heat (J/g°C)
-----> ΔT = change in temperature (°C)
You can plug the given values into the equation and simplify to isolate "c".
Q = mcΔT <----- Equation
1500 J = (300.0 g)c(40 °C - 25°C) <----- Insert values
1500 J = (300.0 g)c(15) <----- Subtract
1500 J = (4500)c <----- Multiply 300.0 and 15
0.33 = c <----- Divide both sides by 4500
