What happens to the energy released by an exothermic reaction
1) it increases the bond energy of the reactants
2) it raises the temperature of the products
3) it is released into the surroundings
it raises the temperature of the reactants

If the energy is released by exothermic reaction, 3) it is released into surroundings; and it raises the products temperature.

An exothermic reaction is that chemical reaction where the heat is produced and released to the surrounding during the chemical reaction. The products are warmer than the reactants due to the raise in temperature (due to heat). In this reaction, the heat produced is released to the surrounding to attain the thermal equilibrium condition.

The net enthalpy in endothermic is positive whereas in exothermic reaction it is negative. The change in energy is measured using calorimeter.  

away from the curb

explanation:

the wheels would then hit the curb if it started to rolling, decreasing the chance of an accident.

they all get energy from eating other animals, dead animals to be more precise.

hienas tends to steal pray from other animals. crows and vultures tend to eat dead animals and leftovers.

hope it ,
