Question

Calcium bicarbonate produced in the chemical weathering process of carbonation ________.

A) is rare
B) eventually transforms into diamonds
C) is difficult to remove from the spot where it was formed
D) is very soluble
E) is very resistant to erosion

Answer 1

Calcium bicarbonate formed during the process of carbonation in chemical weathering is very soluble in water, easily carried away, and does not transform into diamonds nor remain fixed at its formation site.

Step-by-step explanation:

The student asked about the properties of calcium bicarbonate produced in the chemical weathering process of carbonation. The correct answer to this question is that calcium bicarbonate is very soluble in water. This solubility is due to the interactions with carbon dioxide in natural water, where rainwater saturated with CO₂ can dissolve limestones, leading to the formation of calcium bicarbonate. The dissolved calcium bicarbonate is then easily carried away with the water, indicating that it does not remain fixed at the site of its formation and is not resistant to erosion. It certainly does not transform into diamonds, which requires very different conditions of extreme pressure and temperature underground.
