Question

1. For the following reaction, 4.68 grams of butane (C₄H₁₀) are allowed to react with 20.3 grams of oxygen gas .

butane (C₄H₁₀)(g) + oxygen(g) ---> carbon dioxide(g) + water(g)

What is the maximum amount of carbon dioxide that can be formed?

What is the FORMULA for the limiting reagent?

What amount of the excess reagent remains after the reaction is complete?

2. For the following reaction, 24.8 grams of diphosphorus pentoxide are allowed to react with 12.6 grams of water .

diphosphorus pentoxide(s) + water(l) ---> phosphoric acid(aq)

What is the maximum mass of phosphoric acid that can be formed?

What is the FORMULA for the limiting reagent?

What mass of the excess reagent remains after the reaction is complete?

3. For the following reaction, 46.0 grams of iron are allowed to react with 18.4 grams of oxygen gas .

iron(s) + oxygen(g) ---> iron(III) oxide(s)

What is the maximum mass of iron(III) oxide that can be formed?

What is the FORMULA for the limiting reagent?

What mass of the excess reagent remains after the reaction is complete?

Answer 1

first check the limiting Reagents.

then using limiting Reagent find the mass of product produced.
