I chose them balanced chem equation Mg+N2–> Mg3N2 I have to use that in these:

1. If 12.0 moles of a reactant (you choose which reactant if there is more than one) react how many moles of product (you choose which product if there is more than one) forms? Pls show work

2. If 100.0 g of a reactant (you choose which reactant if there is more than one) reacts, how many grams of product forms? Pls show work

3. How many atoms of reactant (you choose which reactant if there is more than one) would have to react to form 6.0x10^23 Atoms of product (you choose which product if there is more than one) pls show work
