Answer:
1. highest is 25.7c° and lowest is 20.0c°
2.Is Exothermic. An Endothermic Reaction is a chemical reaction that absorbs energy in the form of light or heat. In it, the energy or enthalpy of the reactants is less than that of the products. An Exothermic Reaction is a chemical reaction that gives off energy in the form of light or heat.
3. Reactans.
4. The substance(s) to the left of the arrow in a chemical equation are called reactants. A reactant is a substance that is present at the start of a chemical reaction. The substance(s) to the right of the arrow are called products . A product is a substance that is present at the end of a chemical reaction.
