Answer 1

Answer:

1.By indicating 'physical state' of the reactants and products.

2.By balancing it.

Giving the name of the components which is added when reaction is takes place.

4.By indicating 'heat exchange' takes place in the reaction.

5.By indicating the 'conditions' under which the reaction takes place

Answer 2

Answer:

A chemical equation can be made more informative by:

1. Mentioning the physical states of the reactants and products. For eg. s for solid, l for liquid and aq for an aqueous solution. If a gas is evolved during the reaction, it is indicated by an arrow pointing upwards and if a precipitate is formed, an arrow pointing downwards.
2. Mentioning the molecular formulae of the reactants and products.
3. Mentioning special conditions like heat, pressure or presence of catalyst above or below the arrow joining the reactant and product sides.
