**When acetylene is passed through an ammoniacal solution of silver oxide, an explosive that does not contain hydrogen is formed. What is the structural formula of the compound? How many liters of acetylene will be required to obtain 24 g of the reaction product if its yield is 80% of the theoretical?**

C2H2 + Ag2O = C2Ag2 + H2O

Let’s find the amount of substance C2Ag2.

n = m: M.

M (C2Ag2) = 240 g / mol.

n = 24 g: 240 g / mol = 0.1 mol.

Let’s find the quantitative ratios of substances.

For 1 mol of C2Ag2) there is 1 mol of C2H2.

Substances are in quantitative ratios 1: 1.

The amount of C2H2 substance and the amount of C2Ag2 substance are equal.

n (C2H2) = n (= C2Ag2) = 0.1 mol.

Find the volume C2 H2.

V = n Vn, where Vn is the molar volume of the gas equal to 22.4 l / mol.

V = 0.1 mol × 22.4 L / mol = 2.24 L.

– 100%,

X – 80%,

X = (2.24 × 80%): 100% = 1.792 HP.

Ag – C ≡ C- Ag.

Answer: 1,792 l.
