Achange in means that a chemical reaction has occurred. a) the energy and mass b) the kinds of atoms involved c) the properties and identity of the reacting substances d) the energy and kinds of atoms of the reacting substances

 c) the properties and identity of the reacting substances

Explanation: A chemical change is one in which the chemical composition of the atoms change. Every change follows law of conservation of mass and energy i.e. the mass and energy of the system remains conserved.

The above equation represents a chemical change in which hydrogen  and oxygen in gaseous form react to form water in liquid state. In this reaction, Oxygen is a supporter of combustion, hydrogen does not support combustion, whereas water is used to prevent combustion.

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.
