Magnesium oxide forms from magnesium metal and oxygen gas O2. Write a word equation and an unbalanced formula including physical states.

See explanation

Explanation:

The word equation is just a statement of the reaction in words as follows;

Magnesium oxide > Magnesium metal + oxygen gas

An unbalanced stoichiometric equation doesn't have equal number of atoms of each element on both sides.

Hence the unbalanced stoichiometric equation is as follows;

MgO(s) > Mg(s) + O2(g)

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.
