Question

1. when burning 180 g of glucose in the presence of 192 g of oxygen, water and carbon dioxide are produced. if 108 g of water is produced, how many grams of carbon dioxide are produced? (1 point) 264 g 17. after two elements react to completion in a closed container, the ratio of their masses in the container will be the same as before the reaction. which law describes this principle? (0.5 points) enter your answer

Explanation:

Step1: Sum reactant masses

$180\ \text{g} + 192\ \text{g} = 372\ \text{g}$

Step2: Solve for CO₂ mass

$372\ \text{g} - 108\ \text{g} = 264\ \text{g}$

The principle that mass is conserved in a closed system, so the mass ratio remains unchanged.

Answer:

264 g
