Balance the following reaction. choose "blank" if no coefficient is needed. mgcl2 + agno3 → agcl + mg(no3)2 really need guys

Explanation: According to law of conservation of mass, the mass can neither be created nor be destroyed. Thus the mass of products must be equal to the mass of reactants.

In order to have same mass on both sides of the chemical equation, the number of atoms of each element must be same in reactants as well as products. Thus the equation is balanced.

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 .
