Select the correct answer. Based on the reactivities of the elements involved, which reaction will form products that are more stable than the reactants?

A. 2AlBr3 + 3Zn → 3ZnBr2 + 2Al

B. CaBr2 + 2Na → 2NaBr + Ca

C. MgBr2 + H2 → 2HBr + Mg

D. BaBr2 + Ca → CaBr2 + Ba

E. 2LiBr + Ba → BaBr2 + 2Li

answer

i think the answer is a) as air pressure in an area increases, the density of the gas particles in that area decreases.

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.
