Answer:

Mass of C₂H₄N₂ produced = 3.64 g

Explanation:

The balanced chemical equation for the reaction is given below:

3CH₄ (g) + 5CO₂ (g) + 8NH₃ (g) → 4C₂H₄N₂ (g) + 10H₂O (g)

From the equation, 3 moles of CH₄ reacts with 5 moles of CO₂ and 8 moles of NH₃ to produce 4 moles of C₂H₄N₂ and 10 moles of H₂O

Molar masses of the compounds are given below below:

CH₄ = 16 g/mol; CO₂ = 44 g/mol; NH3 = 17 g/mol; C₂H₄N₂ = 56 g/mol; H₂O g/mol

Comparing the mole ratios of the reacting masses;

CH₄ = 1.65/16 = 0.103

CO₂ = 13.5/44 = 0.307

NH₃ = 2.21/17 = 0.130

converting to whole number ratios by dividing with the smallest ratio

CH₄ = 0.103/0.103 = 1

CO₂ = 0.307/0.103 = 3

NH₃ = 0.130/0.103 = 1.3

Multiplying through with 5

CH₄ = 1 × 5 = 5

CO₂ = 3 × 5 = 15

NH₃ = 1.3 × 5 = 6.5

Therefore, the limiting reactant is NH₃

8 × 17 g (136 g) of NH₃ reacts to produce 4 × 56 g (224 g) of C₂H₄N₂

Therefore, 2.21 g of NH₃ will produce (2.21 × 224)/136 g of C₂H₄N₂ = 3.64 g of C₂H₄N₂

Mass of C₂H₄N₂ produced = 3.64 g

kondaur [170]

Explanation:

(a) Dry ice is solid carbon dioxide and its chemical formula is solid CO_{2}.

(b) Sodium chloride is commonly known as salt in daily life. Hence, chemical formula of salt is NaCl.

(c) Laughing gas is also known as dinitrogen monoxide. Hence, its chemical formula is N_{2}O.

(d) Marble (chalk limestone) is chemically known as calcium carbonate. Hence, its chemical formula is CaCO_{3}.

(e) Baking soda is chemically known as sodium bicarbonate. Hence, its chemical formula is NaHCO_{3}.

(f) Ammonia has a chemical formula as NH_{3}.

(g) Water has a chemical formula as H_{2}O.

(h) Milk of magnesia is a base and it is chemically known as magnesium hydroxide. Its chemical formula is Mg(OH)_{2}.

(i) Epsom salt is most often found as heptahydrate of sulfate mineral epsomite. Its chemical formula is usually MgSO_{4}.7H_{2}O. If not present as a heptahydrate then its chemical formula is MgSO_{4}.(H_{2}O)_{x}where, value of x can be equal to 0 to 7.
