Question

matching: match the type of reaction to what it does.

endothermic reactions
endothermic reactions
exothermic reactions
very fast, very energetic exothermic reaction

choose...
explosion
require energy to be added continuously (heat/light/electricity)
require heat from the environment to keep going
release energy as heat and can be dangerous

Explanation:

Analyze endothermic reactions

Endothermic reactions absorb energy from their surroundings. One type requires continuous energy input like heat, light, or electricity to proceed. Another description is that they require heat from the environment to keep going.

Analyze exothermic reactions

Exothermic reactions release energy to their surroundings. They release energy as heat and can be dangerous if uncontrolled.

Analyze very fast exothermic reactions

A very fast, highly energetic exothermic reaction is characterized as an explosion.

Match the terms to descriptions

• "Endothermic reactions" matches "Require energy to be added continuously (heat/light/electricity)".
• "Endothermic reactions" (second instance) matches "Require heat from the environment to keep going".
• "Exothermic reactions" matches "Release energy as heat and can be dangerous".
• "Very fast, very energetic exothermic reaction" matches "Explosion".

Answer:

Left Column (Reaction Type)	Right Column (Description)
Endothermic reactions	Require heat from the environment to keep going
Exothermic reactions	Release energy as heat and can be dangerous
Very fast, very energetic exothermic reaction	Explosion
