Question

Fill in the blanks with terms given below.

Answer 1

Answer:

• 1.     d. hydrolysis    chemical reaction involving ions in water (OH⁻ and H⁺ )

• 2.    e. oxidation    chemical reaction in which minerals are weakened by oxygen

• 3.    b. abrasion     away or grinding by friction

• 4.     a. weathering      breakdown and change of rocks and minerals over time

• 5.      c. dissolution     process of dissolving

Explanation:

a. Weathering is due to the reaction of rocks and minerals with the air, water and organisms, which cause the rocks and minerals to breakdown and change. This, normally, is a slow process that involves chemical and physical changes.

b. Abrasion is the wear caused by the friction of the materials.

c. Dissolution is the process of dissolving a solute in a solvent. For instance, salt in water.

d. Hydrolisys is the chemical reaction of a substance with water, being the ions H⁺ or OH⁻ from water the agents responsible for the reaction.

e. Oxidation is the chemical reaction of an element with oxygen. In such reactions, the element transform into a compound that, commonly is weaker than the element. For instance, oxygen oxidates iron producing iron oxide (rust) which is weaker than iron.
