Stoichiometry Problems Answer each of the following questions using the equation provided. be SURE to BALANCE EACH EQUATION BEFORE SOLVING ANY PROBLEMS. SHOW YOUR SOLUTION. 2. Acetylene gas (c2h2) is produced as a result of the following reaction. cac2 + H2O —> C2H2 + ca (oh)2 a. How many grams of ca (0h) 2 would be formed with 4.25 moles of CaC2?
Accepted Answer
Here's how to solve the stoichiometry problem:
1. Balance the Equation:
The balanced equation is:
CaC2 + 2H2O → C2H2 + Ca(OH)2
2. Calculate the Mole Ratio:
The balanced equation shows that 1 mole of CaC2 reacts to produce 1 mole of Ca(OH)2.
3. Convert Moles of CaC2 to Moles of Ca(OH)2:
Since the mole ratio is 1:1, 4.25 moles of CaC2 will produce 4.25 moles of Ca(OH)2.
4. Convert Moles of Ca(OH)2 to Grams:
Find the molar mass of Ca(OH)2: Ca (40.08 g/mol) + 2
O (16.00 g/mol) + 2
H (1.01 g/mol) = 74.10 g/mol
Multiply the moles of Ca(OH)2 by its molar mass:
4.25 moles
74.10 g/mol = 315.43 g
Answer: 315.43 grams of Ca(OH)2 would be formed with 4.25 moles of CaC2.
