two different liquids are mixed together. which observation indicates that an exothermic chemical reaction has taken place?\no an increase in volume\no a decrease in volume\no a rise in temperature\no a drop in temperature

Answer

Brief Explanations:

Exothermic reactions release heat. When heat is released during a chemical - reaction between two liquids, it causes the temperature of the surroundings (including the liquid mixture) to rise. Volume changes are not characteristic indicators of exothermic chemical reactions.

Answer:

C. a rise in temperature
