Energy is involved in some way in all chemical reactions. Which type of reaction involves the absorption of energy from the surroundings?
Which type of reaction involves the release of energy into the surroundings?
If you mix two reactants together that produce a new product as the result of chemical reaction, and the
reaction flask feels warm to the touch, which type of reaction is it?
If a reaction taking place in a flask shows a drop in temperature, which type of reaction is it?
DONE

1. endothermic reactions involve absorption oof energy from the surroundings

2. exothermic reactions release energy to its surroundings

3. If the reaction flask feels warm, that is the result of an exothermic reaction because there was energy produced from the reaction that caused the reaction flask to gain thermal energy. This thermal energy would cause the flask to feel warm.

4. If the reaction shows a drop in temperature, it is the result of an endothermic reaction because energy was absorbed from the surroundings. Temperature is the measure of average kinetic energy, meaning when the amount of energy decreases, the temperature will also decrease.

oh it is true if thats what you are asking

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )
