Question

1. Consider the following reaction: 3 Si + 2 N2 → Si3N4 
2. What is the limiting reactant when 21.44 moles of Si reacts with 17.62 moles of N?
3. How many moles of Si3N4 are formed?

Answer 1

We have given the reaction,

$1.)3Si+2N_2 \rightarrow Si_3N_4$

2.) Si is the limiting reagent.

3.) $7.147$ moles $Si_3N_4$
