Calculate what volume of acetylene C2H2 is formed as a result of interaction
Calculate what volume of acetylene C2H2 is formed as a result of interaction with water of 100 grams of technical calcium carbide (CAC2) containing 4% impurities.
The reaction for the synthesis of acetylene from calcium carbide is described by the following chemical reaction equation:
CaC2 + 2H2O = C2H2 + Ca (OH) 2;
From 1 mole of calcium carbide, 1 mole of acetylene is synthesized.
Let’s calculate the available chemical amount of silicon carbide substance.
M CaC2 = 40 + 12 x 2 = 64 grams / mol;
N CaC2 = 100 x 0.96 / 64 = 1.5 mol;
The same amount of acetylene will be synthesized.
Let’s calculate its volume. To do this, multiply the amount of the substance and the standard volume of 1 mole of the gaseous substance. 1 mole of ideal gas fills a volume of 22.4 liters under normal conditions.
V C2H2 = 1.5 x 22.4 = 33.6 liters;
