Answer 1

`B;\text{ Exothermic Reactions}`

Step-by-step explanation:

Here, we want to get the kind of chemical reaction that releases energy

These kind of chemical reactions for example might be hot to the touch or in large cases like combustion of organic compounds gives out large amount of heat

These kinds of chemical reactions are called exothermic reactions. They are called that as they release heat into the surrounding

Their direct opposites are the endothermic ones that absorb heat from the environment
