Chemical equation balance

1)What information do you get from a balanced chemical equation?

 

2) Why should we balance a chemical equation?

Solutions

Expert Solution

1.From the balanced chemical equation we get the information about the reactants and the product of that reaction and also the type of chemical reaction it is like exothermic or endothermic etc.

 

2. The chemical reaction always be balanced as we know that from the conservation of mass that masses always be same after any reaction. And for that any chemical reaction must be balanced.
