Synthesis and decomposition reactions can be identified based on some typical characteristics,Which statements best describe the characteristics of synthesis and decomposition reactions? Select all that opply. A Synthesis reactions are typically exothermic and the reactants consist of two different elements. B Decomposition resctions are :ypically endothernic and the reactant is a compound with two or more elements. C Synthesis reactions are typically endothermic and the reactant is a compound with two or more elements. Decomposition reactions are typically exothermic and reactants are single elements.

## Step 1<br />A synthesis reaction is a type of chemical reaction where two or more simple substances combine to form a more complex product. This process is typically exothermic, meaning it releases energy in the form of heat. The reactants in a synthesis reaction are usually two different elements.<br /><br />## Step 2<br />A decomposition reaction is a type of chemical reaction where a compound breaks down into two or more simpler substances. This process is typically endothermic, meaning it absorbs energy in the form of heat. The reactant in a decomposition reaction is usually a compound with two or more elements.
