You are conducting a calorimetry experiment using a calorimeter with 500mL of water in its outer chamber to determine the enthalpy of reaction of a chemical reaction. The initial temperature of the water is 25°C. After the reaction, the temperature of the water is 32.5°C. Disregarding any heat loss to the walls of the container, calculate the ΔHr0. The specific heat of water is 4.18 J/(g•K). Answer choices

A.)ΔHr0= 25.7 kJ

B.)ΔHr0= 45.3 kJ

C.)ΔHr0= 105.8 kJ

D.)ΔHr0= 15.7 kJ

E.)ΔHr0= -140.0 kJ

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.

hope this .

you need to have a picture of the atom that way we can answer it
