Which of the following chemical equations depicts a balanced ionic equation?

Option C. 2OH¯ + Ca²⁺ —> Ca(OH)2

Explanation:

OH¯ + Ca²⁺ —> Ca(OH)2

The above equation can be balance as follow:

OH¯ + Ca²⁺ —> Ca(OH)2

There are 2 atoms of OH on the right side and 1 atom on the left side. It can be balance by putting 2 in front of OH¯ as shown below:

2OH¯ + Ca²⁺ —> Ca(OH)2

Next, we shall balanced the charge on both side. This can be obtained as follow:

Total charge on the left side = –2 + 2

Total charge on the left side = 0

Total charge on the right side = 0

Thus, the charge on both side are equal. Hence, the balance ionic equation is:

2OH¯ + Ca²⁺ —> Ca(OH)2

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.
