A scientist studying the reaction between decaborane (B10H18) and oxygen mixed 1.00 x 10^2 grams fo oxygen. Compute the masses of all substances present after the reaction went to completion, generating B2O3 and water as the only products.

Answer 1

Silicon carbide, SiC, is prepared by hearing silicon dioxide in the presence of graphite. Carbon dioxide is the by-product of the reaction. How many grams of silicon carbide can be formed from the reaction of 50.0 grams of graphite with 50.0 grams of silicone dioxide?

Here is what I have so far

SiO2 + 3C > SiC + CO2
