Which statement below is not true of decomposition reactions? they usually require the addition of energy for the reaction to occur. they produce more than one product at the end of the reaction. they begin with more active reactants and end with less active products. they have one compound as the reactant at the beginning of the reaction.

They begin with more active reactants and end with less active products.

Explanation: Decomposition reactions are type of chemical reactions in which one reactant breaks to give two or more than two products.

In order to break the reactant molecules, energy has to be supplied in the form of heat , light or electricity and thus all decomposition reactions are endothermic reactions.

For example:

the only liquid elements at standard temperature and pressure are bromine (br) and mercury (hg). although, elements caesium (cs), rubidium (rb), francium (fr) and gallium (ga) become liquid at or just above room temperature.
