Sagot :
Answer:
190g
Explanation:
Pre-Solving
We are given the following equation:
2C₂H₂ + 5O₂ → 4CO₂ + 2H₂O
We want to know how much carbon dioxide (in grams) is produced if 38 grams of water are produced in the equation.
Solving
We can use dimensional analysis to solve this equation:
[tex]38 g H_2O * \frac{1 mol H_2O}{18 g H_2O} * \frac{4 mol CO_2}{2 mol H_2O} * \frac{44 g CO_2}{1 mol CO_2} = 190 g CO_2[/tex] (rounded to two sig figs).
