step 1 Okay. So to answer question 85, they give us, they provide us that we start with 30 grams of car

When 30.0 g of carbon is heated with silicon dioxide, 28.2...

When $30.0 \mathrm{~g}$ of carbon is heated with silicon dioxide, $28.2 \mathrm{~g}$ of carbon monoxide is produced. What is the percent yield of carbon monoxide for this reaction?
$$\mathrm{SiO}_{2}(s)+3 \mathrm{C}(s) \longrightarrow \mathrm{SiC}(s)+2 \mathrm{CO}(g)$$

Key Concepts

Limiting Reactant

The limiting reactant is the substance that is completely consumed first in a chemical reaction, thereby limiting the quantity of products formed. Identifying the limiting reactant is crucial because it is used to calculate the theoretical yield of the reaction.

Theoretical Yield

The theoretical yield is the maximum amount of product that could be formed from the given amounts of reactants, as predicted by stoichiometry assuming complete reaction with no side reactions. It is determined by using the stoichiometric ratios from the balanced chemical equation in combination with the amount of the limiting reactant.

Stoichiometry

Stoichiometry is the branch of chemistry that deals with the quantitative relationships between reactants and products in a chemical reaction. It relies on the balanced chemical equation to provide ratios which allow for the conversion of masses to moles and vice versa, determining how much of each substance is involved in the reaction.

Percent Yield

Percent yield is a measure of the efficiency of a chemical reaction, calculated by dividing the actual yield by the theoretical yield and multiplying by 100%. This percentage indicates how close the experimental outcomes come to the stoichiometric predictions.
