Question

ZnSo4(s) ➡️ ZnO(s) + SO3(g) - Identify the reactants and products? - identify an easily observable sign that a chemical reaction has taken place?

Answer 1

Consider,

`ZnSO_4(s) to ZnO(s) + SO_3(g)`

Chemical reactions with forward arrows are always read like this sentence. Reactants form products.

Moreover, it's easy to observe some chemical reactions, because they produce changes in color or emit light.
