The enthalpy change when a strong acid is neutralized by strong base is -56.1 kj/mol. if 135 ml of 0.450 m hi at 23.15 c is mixed with 145 ml of 0.500 m naoh, also at 23.15 c, what will the maximum temperature reached by the resulting solution? [assume that there is no heat loss to the container, that the specific heat of the final solution is 4.18 j/g• c, and that the density of the final solution is that of water.]

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.

one negative thing it that it can kill water animals. another negative thing is it can cause the destruction of ecosystem. one way water pollution can be reduced is to conserve energy.
