Question

Water is seen here on earth in all three states of matter. write the balanced chemical equation that shows:

a. liquid water freezing
b. boiling
c. ice melting
d. snowflakes forming from water vapor in the clouds

Answer 1

Water can exist in all three states of matter: solid, liquid, and gas. The balanced chemical equations for the state changes are as follows: a. H2O(l) → H2O(s) for liquid water freezing, b. H2O(l) → H2O(g) for boiling, c. H2O(s) → H2O(l) for ice melting, and d. H2O(g) → H2O(s) for the formation of snowflakes from water vapor.

Step-by-step explanation:

a. The balanced chemical equation for the freezing of water (liquid to solid) is: H2O(l) → H2O(s). In this reaction, the water molecules lose energy and arrange themselves into a solid structure, forming ice.

b. The balanced chemical equation for boiling water (liquid to gas) is: H2O(l) → H2O(g). In this reaction, the water molecules gain enough energy to overcome the intermolecular forces and escape into the gas phase.

c. The balanced chemical equation for melting ice (solid to liquid) is: H2O(s) → H2O(l). In this reaction, the solid ice absorbs heat energy and breaks apart into individual water molecules, forming liquid water.

d. The formation of snowflakes from water vapor in the clouds involves the process of deposition, where water vapor directly changes into solid ice without going through the liquid state. The balanced chemical equation for this process can be represented as: H2O(g) → H2O(s).
