Answer:

1328 K or 1055 °C

Explanation:

To find the new temperature, you need to use the Combined Gas Law:

P₁V₁ / T₁ = P₂V₂ / T₂

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. After converting the temperature (T₁) from Celsius to Kelvin, you can plug the values into the equation and simplify.

P₁ = 1.0 atm                                                P₂ = 0.90 atm

V₁ = 200 L                                                  V₂ = 1000 L

T₁ = 22 °C + 273.15 = 295.15 K                 T₂ = ? K

P₁V₁ / T₁ = P₂V₂ / T₂

(1.0 atm)(200 L) / 295.15 K = (0.90 atm)(1000 L) / T₂

0.6776 = (0.90 atm)(1000 L) / T₂

(0.6776) x T₂ = (0.90 atm)(1000 L)

(0.6776) x T₂ = 900

T₂ = 1328 K

T₂ = 1055 °C

Mn(s) metal will spontaneously react with Zn²⁺(aq), but will not

spontaneously react with Mg²⁺ (aq)

The Eo value of an electrochemical cell determines its spontaneity. Positive Eo electrochemical cells are spontaneous, and vice versa.

The relevant Eo of the half-cell in this instance are as follows for Mn(s) metal

Zn2+/Zn = -0.763v for Eo

2.37v for Eo Mg2+/Mg.

Mn2+/Mn = -1.18v for Eo.

Consequently, the equation for an Eo cell (with Zn as one of the half-cells) is: Eo Zn2+/Zn - Eo Mn2+/Mn = -0.763 - (-1.18) = 0.417v.

On the other hand, the equation for an Eo cell (with Mg as one of the half-cells) is: Eo Mg2+/Zn - Eo Mn2+/Mn = -2.37 - (-1.18) = -1.19v.

As a result, Mn(s) metal will spontaneously react with Zn2+(aq), but not with Mg2+ (aq)

One way to describe an acid's potency is by its pKa value. The acid dissociation constant, or pKa, is the negative log of the pKa value. A stronger acid is indicated by a lower pKa value. In other words, a lower value means that the acid dissociates in water more completely.

The logarithm of Ka's negative value is denoted as pKa. The logarithmic inverse of the H+ concentration is pH. Acidity indication. An acid's pKa value tells you if it's a strong acid or a weak acid. The pH scale shows how acidic or alkaline a system is.

No, the mass does not change.

Freezing is a change in physical state, not a chemical reaction. No matter is added or taken away.

As water transitions to ice, no molecules are lost; it is boiling so it is not turning into a gas. There is a very, very small amount of mass lost in the form of energy as the water loses it's heat, but this amount of mass is so insignificant it practically can't be measured. In other words, it's negligible.

The correct answer would be 0.034 g/L.

What we are trying to do here is to convert from milligram to gram and from deciliter to liter.

First, let's do the milligram to gram conversion.

1 mg = 0.001 g

Therefore,

3.4 mg = 3.4 x 0.001 = 0.0034 g

In order to convert from deciliter to liter.

1 deciliter = 0.1 L

Thus, 3.4 mg/dL = 0.0034g/0.1 L = 0.034 g/L

From the calculation, the equilibrium constant is obtained as 3. Option A

The term equilibrium constant shows the extent to which we could see the conversion of the reactants to products in a reaction system. Now we know that the equilibrium constant can be obtained by the use of the formula;

K = [H2] [I2]/[HI]^2

Now we have that at equilibrium;

[H2]  = 0.5 M

[I2] = 1.5 M

[HI] = 0.5M

It then follows that;

K = 1.5 * 0.5/( 0.5)^2

K = 3

Answer:

44.8 grams

Explanation:

The density exists as a ratio comparing the mass of a piece of copper per 1 cm³. Since you have been given a new volume, you can set up a proportion to find the new mass.

[tex]\frac{8.96 grams}{1.00 cm^3} =\frac{?grams}{5.00cm^3}[/tex]                                         <----- Proportion

[tex]44.8 = (1.00cm^3)(?grams)[/tex]                              <----- Cross-multiply

[tex]44.8= ?grams[/tex]                                                 <----- Divide both sides by 1.00

The enthalpy change of the reaction is -44.79 kJ/mol.

We can define the enthalpy change as the energy that is given out or taken in in a reaction. it can be calculated from the enthalpies of formation of species by the use of the relation;

ΔH = ∑Enthalpy of formation of products -  ∑Enthalpy of formation of reactants

ΔHfC2H4(g) = +52kJ/mol

ΔHf H2O(g) = - 241.82 kJ/mol

ΔHf CH3CH2OH(g)= -234.61 kJ/mol

ΔHrxn  = (-234.61) - [52 + (- 241.82 )]

ΔHrxn  = (-234.61) - (-189.82)

The specific heat of the metal, given the data from the question is 0.60 J/gºC

The following data were obtained from the question:

The specific heat capacity of the sample of gold can be obtained as follow:

According to the law of conservation of energy, we have:

Heat loss = Heat gain

MC(T –Tₑ) = MᵥᵥC(Tₑ – Tᵥᵥ)

74 × C(94 – 32) = 120 × 4.184 (32 – 26.5)

C × 4588 = 2761.44

Answer:doesn't  one more. chlorine.  one fewer.   hydrogen

Explanation:

Jon's equation does support his claim that matter is conserved during the chemical reaction because the reactants contain the same number of atoms compared to the products.

In a balanced chemical equation, the total number of atoms of each element in the reactants must be equal to the total number of atoms of the same element in the products.

This is known as the law of conservation of mass, which states that matter cannot be created or destroyed during a chemical reaction.

As long as the equation is balanced, showing the same number of atoms on both sides, it confirms that matter is conserved throughout the reaction, supporting Jon's claim.

Considering the definition of empirical and molecular formula, the pair C₆H₆ and C₃H₃ shares the same empirical formula.

The empirical formula is the simplest expression to represent a chemical compound, and indicates the elements that are present and the minimum proportion in whole numbers between its atoms. This formula is also known as the “minimum formula”.

That is, the empirical formula is the expression of the simplest ratio between the atoms of a chemical compound and indicates the different elements that make up the molecule and the relationship between them. But it does not indicate the actual formula of the compound.

The molecular formula is the actual formula of the molecule, it tells us the types of atoms and the number of each type that participate in the formation of the molecule.

In this case, the pair C₆H₆ and C₃H₃ shares the same empirical formula. In the first case, the ratio of carbon atoms to hydrogen atoms is 6:6 or 1:1, while in the second case said ratio is 3:3 or 1:1. Therefore, the relationship is the same, so they have the same empirical formula.

In summary, the pair C₆H₆ and C₃H₃ shares the same empirical formula.

Answer:

103 mmHg

Explanation:

To find the new pressure, you need to use the Combined Gas Law:

P₁V₁ / T₁ = P₂V₂ / T₂

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. You can find the new pressure (P₂) after converting the temperatures from Celsius to Kelvin.

P₁ = 365.7 mmHg                                        P₂ = ? mmHg

V₁ = 75.1 L                                                    V₂ = 242.9 L

T₁ = 33.2 °C + 273.15 = 306.35 K              T₂ = 6.5 °C + 273.15 = 279.65 K

P₁V₁ / T₁ = P₂V₂ / T₂                                           <----- Combined Gas Law

(365.7 mmHg)(75.1 L) / 306.35 K = P₂(242.9 L) / 279.65 K    <----- Insert values

89.649 = P₂(242.9 L) / 279.65 K                     <----- Simplify left side

25070.433 = P₂(242.9 L)                                 <----- Multiply both sides by 279.65

103 = P₂                                                            <----- Divide both sides by 242.9

From the stoichiometry of the reaction, the volume of the steam produced is 82.9 L

The term combustion is the term that is used to describe the kind of reaction that occurs when a substance is being burnt in oxygen. It is an oxidation reaction and the octane is burnt to produce carbon dioxide and steam.

We can try to write down the equation of the reaction as follows;

2C8H18(g) + 25O2(g) ------> 16CO2(g) + 18H2O(g)

Now 1 mole of octane gas occupies 22.4 L

x moles of octane gas occupies 9.1 L

x = 9.1 L  *  1 mole /22.4 L

x = 0.41 moles

Now;

2 mole of octane gas produces 18 moles of steam

0.41 moles of octane gas produces  0.41 moles  * 18 moles/2 mole

= 3.7 moles

1 mole of steam occupies 22.4 L

3.7 moles of steam occupies 3.7 moles *  22.4 L/1 mole

Answer:

0.116 M

Explanation:

(Step 1)

Calculate the amount of moles using the molarity ratio.

100.0 mL / 1,000 = 0.1000 L

Molarity = moles / volume

0.695 M = moles / 0.1000 L

0.0695 = moles

(Step 2)

Calculate the new molarity using the moles and new volume.

500.0 mL / 1,000 = 0.5000 L

Molarity = moles / volume

Molarity = 0.0695 moles / (0.1000 L + 0.5000 L)

Molarity = 0.0695 moles / (0.6000 L)

Molarity = 0.116 M
