Which statement correctly describes how hydrolysis causes chemical weathering?

Question

Water reacts with carbon dioxide to produce carbonic acid, weakening the rock.
Water reacts with minerals in rocks to produce carbonic acid, weakening the rock.
Water reacts with minerals in rocks to produce clay, weakening the rock.
Water reacts with carbon dioxide to produce clay, weakening the rock.

Answer 1

The correct statement that describes how hydrolysis causes chemical weathering is:

Water reacts with minerals in rocks to produce clay, weakening the rock.

In hydrolysis, the water interacts with certain minerals, often silicate minerals, leading to chemical reactions that can yield clay minerals and other soluble products, thus weakening the structural integrity of the rock.

Answer 2

Which is responsible for the formation of rust on metals?
oxidation
carbonic acid
acid rain
hydrolysis

Answer 3

The formation of rust on metals is primarily due to oxidation.

When iron reacts with oxygen in the presence of moisture (water), it undergoes an oxidation reaction, leading to the formation of iron oxide, commonly known as rust.

Answer 4

How does air pollution impact chemical weathering?
Pollutants react with minerals inside rocks and weaken them.
Pollutants cover rocks with a toxic layer that weakens them.
Pollutants mix with air and water to make acid rain.
Pollutants prevent carbon from mixing with water.

Answer 5

The correct statement regarding how air pollution impacts chemical weathering is:

Pollutants mix with air and water to make acid rain.

Air pollutants, such as sulfur dioxide and nitrogen oxides, can dissolve in rainwater and form acids, leading to acid rain. This acidic precipitation enhances the chemical weathering process by reacting with minerals in rocks and weakening them.

Answer 6

What products are produced when water reacts with sodium in rocks?
salt solution and clay minerals
salt solution and iron oxide
clay minerals and calcium carbonate
clay minerals and iron oxide clay minerals and iron oxide

Answer 7

The correct answer to the question about the products produced when water reacts with sodium in rocks is:

salt solution and clay minerals.

When water reacts with sodium-containing minerals (such as feldspar), it can lead to the formation of clay minerals (like kaolinite) and soluble sodium salts, resulting in a salt solution.
