If 50.0 g of silicon dioxide is heated with an excess of carbon, 27.9 g of silicon carbide is produced. What is the percent yield of the reaction

The percent yield of the reaction is 83.5 %

Explanation:

The given balanced equation is

is the limiting reagent as it limits the formation of product and is the excess reagent.

According to stoichiometry :

60.08 g of produce = 40.11 of

Thus 50.0 of will produce=  of

 Experimental yield of SiC = 27.9 g

Percent yield =

Thus  percent yield of the reaction is 83.5 %
