2An [blank_start]exothermic[blank_end] reaction is a chemical reaction that [blank_start]releases[blank_end] energy by light or heat. It is the opposite of an [blank_start]endothermic[blank_end] reaction.. Expressed in a chemical equation: reactants → products + energy!
- AEndothermic
- BExothermic
- Creleases
- Dtakes in
- Eendothermic
- Fexothermic
- GLight
- HHeat
- IReversible
3Because exothermic reactions give out heat, it may result in a change of amount of energy in the surrounding areas.
- AVerdadeiro
- BFalso
4Combustion is an example of an exothermic reaction!
- AVerdadeiro
- BFalso
5What makes this image an exothermic reaction?
- AIt gives out heat
- BIt gives out light
- CIt gives out energy
- DIt gives out sound
- EIt gives out free sweets
6As exothermic reactions release [blank_start]heat[blank_end] energy, the product of the [blank_start]reaction[blank_end] is the heat, with whatever the heat is caused by being the reactant.
- AChemical
- BHeat
- CElectrical
- DNuclear
- EGravitational Potential
- FEquation
- GSum
- HReaction
- IExperiment
- JRecipe
7Exothermic reactions are the main type of reactions that happen.
