how would i name the following:?

Question

1. 2Cu=O2--->2CuO
2. 2 Fe(No3)3 +3Na2Co3---> 6NaNo3 +Fe2(Co3)3
3. Mg3N2---> 3 Mg +N2

Answer 1

1. 2 Cu + O2 ---> 2 CuO
Copper plus Oxygen yields Copper (II) Oxide
(You might have said metallic Copper and molecular Oxygen)

2. 2 Fe(NO3)3 + 3 Na2CO3 ---> 6 NaNO3 + Fe2(CO3)3
Iron (III) nitrate plus Sodium carbonate yields Sodium nitrate plus Iron (III) carbonate.

3. Mg3N2 ---> 3 Mg + N2
Magnesium nitride yields (or decomposes) into Magnesium plus Nitrogen (or Magnesium metal and molecular Nitrogen).
