Question

How to predict the states of matter of reactants and products in chemical reactions?

Answer 1

Predicting the states of matter of reactants and products in chemical reactions

• If the melting point and boiling points of the compounds are below room temperature then the compound is a solid.
• If the melting point and boiling points of the compounds are above room temperature then the compound is a gas.
• If the boiling point of the compound is above room temperature and the melting point is below the room temperature the compound is a liquid.
• States of matter of reactants and products are represented by (s) for solid, (l) for liquid, (g) for gas, or (aq) for aqueous solution.
• The amount of energy in molecules of matter determines the state of matter.

Hence, by melting and boiling point of a substance, the states of matter of reactants and products in chemical reactions can be predicted.
