Mia mixes hydrochloric acid (hcl) and sodium hydroxide (naoh). she observes that the reaction mixture becomes warm. what could mia conclude?

The reaction is exothermic in nature.

Explanation:

Exothermic reactions are defined as the reactions in which energy of the product is lesser than the energy of the reactants. The total energy is released in the form of heat and for the reaction comes out to be negative. The reaction mixture becomes warm.

Endothermic reactions are defined as the reactions in which energy of the product is greater than the energy of the reactants. The total energy is absorbed in the form of heat and for the reaction comes out to be positive.The reaction mixture becomes cold.

When hydrochloric acid and sodium hydroxide are mixed, the mixture becomes warm and thus it can be concluded that the reaction is exothermic in nature.

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
