During a chemical reaction, 25.0 g of propane burns with 90.7 g of oxygen to form carbon dioxide and water. what mass of carbon dioxide and water is formed? during a chemical reaction, 25.0 g of propane burns with 90.7 g of oxygen to form carbon dioxide and water. what mass of carbon dioxide and water is formed? 115.7 g 90.7 g 65.7 g 25.0 g

The chemical equation for the combustion of propane can be represented as,

1 mol propane requires 5 mol oxygen for complete reaction to produce 3 mol carbon dioxide and 4 mol water.

Mass of propane = 25.0 g

Mass of oxygen = 90.7 g

The total mass of reactants = 25.0 g + 90.7 g = 115.7 g

According to Law of conservation of mass, the total mass of reactants will be equal to the total mass of products formed in a chemical reaction.

Therefore, here the mass of water and carbon dioxide will be 115.7 g

Correct a. 115.7 g

they it depends on if one believes about radioactivity, they make a geiger counter beep but maybe it was going to beep anyway electronics do wierd things all the time or it was programmed to beep near certain metals.
