Question

Decomposition Reactions

1. sodium iodide →
2. magnesium nitride→
3. manganese (II) chloride >
4. potassium silicide>

Predict the reactants
Write out and solve the chemical equation

Answer 1

NaI = Na + I2 (diatomic)

Mg3N2 = Mg + N2

MnCl2 = Mn + Cl2

K4Si = K + Si

Step-by-step explanation:

First convert these written equations into chemical symbols.

Sodium iodide = NaI

Magnesium Nitride = Mg3N2

Manganese II Chloride = MnCl2

Potassium Silicide = K4Si

Then we predict the products by separating the elements.

NaI = Na + I2 (diatomic)

Mg3N2 = Mg + N2

MnCl2 = Mn + Cl2

K4Si = K + Si

However, notice that these are not balanced. If you want you can balance these.
