Answer:
Yes they have gotten better overtime
Explanation:
2. 0.05733 mol CuCl2 (1 mol Cu(OH)2 / 1 mol CuCl2) = 0.05733 mol Cu(OH)2 <-- It's the same because there's a 1:1 ratio between the reactant and the product.
Answer:
The actual yield from this reaction is 92.39 grams CaCl2
Explanation:
Step 1: Data given
% yield = 80.34 %
Expected amount of Calcium chloride (CaCl2) = 115 grams
Step 2: The balance equation
CaCO3 + 2HCl → CaCl2 + CO2 + H2O
Step 3: Calculate actual yield
% yield = 80.34 % = 0.8034 = actual yield / theoretical yield
actual yield = 0.8034 * 115.0 grams
actual yield = 92.39 grams
The actual yield from this reaction is 92.39 grams CaCl2
