Answer:

43.75 g of Nitrogen

Explanation:

We'll begin by calculating the mass of 1 mole of NH₄NO₃. This can be obtained as follow:

Mole of NH₄NO₃ = 1 mole

Molar mass of NH₄NO₃ = 14 + (4×1) + 14 + (3×16)

= 14 + 4 + 14 + 48

= 80 g/mol

Mass of NH₄NO₃ =?

Mass = mole × molar mass

Mass of NH₄NO₃ = 1 × 80 = 80 g

Next, we shall determine the mass of N in 1 mole of NH₄NO₃.

Mass of N in NH₄NO₃ = 2N

= 2 × 14

= 28 g

Thus,

80 g of NH₄NO₃ contains 28 g of N.

Finally, we shall determine the mass of N in 125 g of NH₄NO₃. This can be obtained as follow:

80 g of NH₄NO₃ contains 28 g of N.

Therefore, 125 g of NH₄NO₃ will contain = (125 × 28) / 80 = 43.75 g of N.

Thus, 125 g of NH₄NO₃ contains 43.75 g of Nitrogen

Answer: The heat of combustion per mole for acetylene is 227.7 kJ/mol.

Explanation:

The combustion equation of acetylene is as follows.

[tex]C_{2}H_{2} + \frac{5}{2}O_{2} \rightarrow 2CO_{2} + H_{2}O[/tex]

Formula to calculate enthalpy of formation for a reaction is as follows.

[tex]\Delta H^{o}_{rxn} = \sum \Delta H_{products} - \sum \Delta H_{reactants}\\\Delta H^{o}_{rxn} = [2\Delta H^{o}_{f}(CO_{2}) + \Delta H^{o}_{f} (H_{2}O)] - [\Delta H^{o}_{f}(C_{2}H_{2}) + \frac{5}{2} \Delta H^{o}_{f} O_{2}]\\-1299.5 = 2(-393.5) + (-285.8) - \Delta H^{o}_{f} (C_{2}H_{2})\\\Delta H^{o}_{f} (C_{2}H_{2}) = 227.7 kJ/mol[/tex]

Thus, we can conclude that heat of combustion per mole for acetylene is 227.7 kJ/mol.

Answer:

C. 13.65.

Explanation:

With the given hydroxide ion concentration [OH⁻] we can calculate the pOH of the solution, using the following formula:

Then, with the pOH we can proceed to calculate the pH of the solution, with the formula:

The correct answer is option C. 13.65.

Answer:

the answer is c

Explanation:

i did the test

The enthalpy of the formation of water is -285.8 kJ/mol. The information that can be made by the statement is heat is released during the process. The correct option is C.

Enthalpy is the volume times the pressure times the internal energy of the system. It is an entity of thermodynamics. It is the measurement of the energy in a thermodynamic system. The enthalpy totals the internal energy plus pressure and volume.

The statement that is given here is given that enthalpy is -285.8 kJ/mol. The value is negative, so the energy is released here. When energy is gained the energy will be positive and when the energy is released it is negative.

Thus, the correct option is C, heat is released during the process regarding the given statement of enthalpy.

A compound is a pure substance that is composed of elements chemically bonded in definite proportions. A compound can be broken down into simpler substances only by chemical reactions, such as electrolysis.

A solution is a homogeneous mixture, meaning that it is the same throughout. A solution is composed of one or more solutes dissolved in a solvent. The proportions of the solute(s) can vary, as the components of a solution are not chemically bonded. The components of a mixture can be separated by physical means, such as filtration and distillation

Answer:

The hypothetical van't Hoff factor of magnesium nitrate,[tex]Mg(NO_3)_2[/tex] is 3 .

Explanation:

Lets calculate -

[tex]Mg(NO_3)_2\rightarrow Mg^2^+ +2NO_3^-[/tex]

We know that ,

[tex]i=\alpha n+(1-\alpha )[/tex]

Dissociation should be 100% for the hypothetical vant hoff factor , that is

[tex]\alpha =1[/tex] and [tex]n=3[/tex] for  [tex]Mg(NO_3)_2[/tex]

Therefore , putting the given values ,

[tex]i=1\times3+(1-1 )[/tex]

[tex]i=3+0[/tex]

[tex]i=3[/tex]

Hence , the answer is 3.

The hypothetical van't Hoff factor of magnesium nitrate is 3.

Van't Hoff factor is a measure of the deviation of a solution from ideal behavior. It depends on the number of particles in the solution. The more the particles in solution, the greater the Van't Hoff factor and the greater the deviation from ideal behavior.

For Mg(NO3)2, the hypothetical van't Hoff factor is 3 since there are three particles in solution when magnesium nitrate is dissolved in water.

Answer:

Option B

Explanation:

The rate law is represented as

Rate of the reaction = [tex]k [A^x][B^y][/tex]

Here K is the rate constant

A is the concentration of substance A

B is the concentration of substance B

Hence, If  reactant A is in the rate law equation, then if its concentration varies then it will impact the rate of the reaction

Hence, option B is correct

Answer:

[tex]C_{alloy}=0.497\frac{J}{g\°C}[/tex]

Explanation:

Hello there!

In this case, according to this calorimetry problem on equilibrium temperature, it is possible for us to infer that the heat released by the metal allow is absorbed by the water for us to write:

[tex]Q_{allow}=-(Q_{water}+Q_{Al})[/tex]

Thus, by writing the aforementioned in terms of mass, specific heat and temperature, we have:

[tex]m_{alloy}C_{alloy}(T_{eq}-T_{alloy})=-(m_{water}C_{water}(T_{eq}-T_{water})+m_{Al}C_{Al}(T_{eq}-T_{Al})[/tex]

Then, we solve for specific heat of the metallic alloy to obtain:

[tex]C_{alloy}=\frac{-(m_{water}C_{water}(T_{eq}-T_{water})+m_{Al}C_{Al}(T_{eq}-T_{Al})}{m_{alloy}(T_{eq}-T_{alloy})}[/tex]

Thereby, we plug in the given data to obtain:

[tex]C_{alloy}=\frac{-(400g*4.184\frac{J}{g\°C} (30.5\°C-10.0\°C)+200g*0.900\frac{J}{g\°C}(30.5\°C-10.0\°C)}{150g(30.5\°C-540\°C)} \\\\C_{alloy}=0.497\frac{J}{g\°C}[/tex]
