Question

Need help figuring out these questions did I do them right

Answer 1

Answer:

The answer to your question is: more less

Explanation:

I suggest you these answers:

a)     PCl₅ (s)     ⇒    PCl₃ (s)  + Cl₂ (g)

b)  ZnBr₂ (aq) + Li₃CO₃ (aq)  ⇒  ZnCO₃ (s)  + LiBr (aq)

c) C₂H₄  + O₂   ⇒    CO₂ (g) + H₂O (l)

Do you have to balance them?
