Analyze the reaction to determine whether the reaction is exothermic or endothermic. explain your reasoning.

The reaction is exothermic.

A net release of energy from the reacting  

substances into the surroundings makes  

this an exothermic reaction.

The equation shows that 891 kJ of energy  

are released as a product.

The graph shows that the reactants have  

greater potential energy than the products.  

This means the difference in energy is  

released to the surroundings.

The reaction is exothermic.  Meaning a net release of energy from the reacting  substances into the surroundings Then the equation shows that 891 kJ of energy  are released as a product.

The graph shows that the reactants have  greater potential energy than the products, this means the difference in energy is  released to the surroundings.

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.
