1. a student performs a reaction in a beaker by reaction silver nitrate with one long copper wire. the student’s thermometer changes from 27°c to 35°c. based on this, is this reaction endothermic, exothermic, or neither? explain your reasoning.
2. list three ways that the student could speed up the reaction in question 1

1.The reaction is exothermic .

2.

Explanation:

1.

As we observed , the reading in the thermometer changes from 27°C to 35°C.

Which means, heat is released when the reaction(displacement reaction) proceeds in the forward direction. - as in to raise the temperature .

Thus it is an exothermic reaction.

2.

According to Le-Chatelier's principle ,

In a reaction , as we increase the temperature or heat , the reaction moves in the direction that consumes or uses the heat.

the molecules move in straight line until they collide with each other or with the walls of the container. collisions are perfectly elastic; when two molecules collide, they change their directions and kinetic energies, but the total kinetic energy is conserved.
