How do freeze-thaw cycles cause weathering?

Chemistry
1 answer:
natta225 [31]3 years ago
8 0

Answer:

A. When water moves into a crack and freezes, it expands and forces the crack wider.

Explanation:

A crack in a rock can fill with water which then freezes as the temperature drops. As the ice expands, it pushes the crack apart, making the crack larger. When the temperature rises again, the ice melts, and the water fills the newer parts of the crack. Once the water freezes again when the temperature drops, the expansion of the ice causes further expansion to the crack.

Why does benzilic acid only precipitate in acidic solution.
Maksim231197 [3]

Benzilic acid will only precipitate in acidic solution to remove excess acid and restore equilibrium.

<h3 /><h3>What are is chemical equilibrium?</h3>

Chemical equilibrium refers to a state in which the rate at which reactant molecules combine to form products is equal to the rate at which products dissociate to form reactants.

For a reaction in equilibrium, any change to distort the equilibrium will cause equilibrium to shift to counter that change.

The components of Benzilic acid exist in equilibrium and will only precipitate in acidic solution because more acid has been added and equilibrium will shift to removal of excess acids.

Therefore, benzilic acid only precipitate in acidic solution in order to remove excess acid and restore equilibrium.

Which of the following scenarios depict an example of colligative properties at play: (A) Pure water freezes at a higher tempera
Veronika [31]

Answer:

(B)

Explanation:

The colligative properties of any given solution are properties that are dependent on the concentration of the molecules or ions of the solute in the solution, and not on the type or identity of that solute. Examples of colligative properties:

1. Lowering of vapour pressure  

2. Elevation of boiling point,

3. Depression of freezing point and

4. Osmotic pressure

(A) is not a colligative property because the scenario talks about the freezing point of a pure solvent and not a solution.

(C) is not a colligative property because the solutions being compared are completely different (the solutes are different).  

(B) is a colligative property because it talks about the freezing point of a solution
