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

Construct the hypothetical phase diagram for metals a and b between room temperature (20c) and 700c, given the following information: * the melting temperature of metal a is 480c. • the maximum solubility of b in a is 4 wt% b, which occurs at 420c. • the solubility of b in a at room temperature is 0 wt% b. • one eutectic occurs at 420c and 18 wt% b–82 wt% a. • a second eutectic occurs at 475c and 42 wt% b–58 wt% a. • the intermetallic compound ab exists at a composition of 30 wt% b–70 wt% a, and melts congruently at 525c.• the melting temperature of metal b is 600c. • the maximum solubility of a in b is 13 wt% a, which occurs at 475c. • the solubility of a in b at room temperature is 3 wt% a.
