In the laboratory a "coffee cup" calorimeter, or constant pressure calorimeter, is frequently used to determine the specific heat of a solid, or to measure the energy of a solution phase reaction. A student heats 62.08 grams of magnesium to 97.96 °C and then drops it into a cup containing 77.81 grams of water at 23.19 °C. She measures the final temperature to be 35.60 °C. The heat capacity of the calorimeter (sometimes referred to as the calorimeter constant) was determined in a separate experiment to be 1.79 J/°C. Assuming that no heat is lost to the surroundings calculate the specific heat of magnesium.

What is the mass in grams of H₂ that can be formed from 54.6 grams of NH₃ in the following reaction?2 NH₃(g) → 3 H₂(g) + N₂(g)


9.6 grams of H₂ can be formed from 54.6 grams of NH₃ in the following reaction: 2NH₃(g) → 3H₂(g) + N₂(g).

  • According to this question, the following balanced equation is given: 2NH₃(g) → 3H₂(g) + N₂(g).

  • First, we convert the mass of ammonia (NH3) to moles as follows:

  • moles of NH3 = 54.6g ÷ 17g/mol

  • moles of NH3 = 3.2mol.

  1. If 2 moles of NH3 produces 3 moles of H2.
  2. 3.2 moles of NH3 will produce 4.8 moles of H2.

  • Next, we convert 4.8moles of H2 to mass as follows:

  • mass of H2 = 4.8 × 2

  • mass of H2 = 9.6g of H2.

  • Therefore, 9.6 grams of H₂ can be formed from 54.6 grams of NH₃ in the following reaction: 2NH₃(g) → 3H₂(g) + N₂(g).

Answer : The mass of H_2 is, 9.64 grams.

Explanation : Given,

Mass of NH_3 = 54.6 g

Molar mass of NH_3 = 17 g/mol

Molar mass of H_2 = 2 g/mol

First we have to calculate the moles of NH_3.

\text{Moles of }NH_3=\frac{\text{Given mass }NH_3}{\text{Molar mass }NH_3}

\text{Moles of }NH_3=(54.6g)/(17g/mol)=3.21mol

Now we have to calculate the moles of H_2

The balanced chemical equation is:

2NH_3(g)\rightarrow 3H_2(g)+N_2(g)

From the balanced reaction we conclude that

As, 2 mole of NH_3 react to give 3 moles of H_2

So, 3.21 mole of NH_3 react to give (3)/(2)* 3.21=4.82 mole of H_2

Now we have to calculate the mass of H_2

\text{ Mass of }H_2=\text{ Moles of }H_2* \text{ Molar mass of }H_2

\text{ Mass of }H_2=(4.82moles)* (2g/mole)=9.64g

Therefore, the mass of H_2 is, 9.64 grams.

Consider the following chemical equilibrium: C(s) + 2H2 (g) <------> CH4 (g)
Now write an equation below that shows how to calculate Kp from Kc for this reaction at an absolute temperature T. You can assume T is comfortably above room temperature. If you include any common physical constants in your equation be sure you use their standard symbols, found in the ALEKS Calculator.



Kp = [CH₄(g)]/[H₂(g)]²(RT)⁻¹


C(s) + 2H₂(g) => CH₄(g)

Kp = Kc(RT)ⁿ

n= change in molar volumes of gas = 1 - 2 = -1
