The characteristic of water that is responsible for frost wedging is that it expands as it freezes and is denoted as option A.
<h3>What is Frost wedging?</h3>
This is referred to a type of physical weathering which is characterized by rocks being broken down into smaller particles through the freezing and thawing process.
This is possible because water is known to expand as it freezes thereby resulting in the expansion of the rocks which forms cracks as a result of frequent freezing and thawing processes.
This is therefore the most appropriate characteristic of water which makes it possible for frost wedging to take place.

Answer:
its made up of both but I would probably say kinetic
Explanation:
Answer:
pH = 12.2
Explanation:
Given data:
Mass of lime = 0.69 g
Volume = 1535 mL (1535 / 1000 = 1.535 L)
pH of solution = ?
Solution:
First of all we will determine the molarity.
Molarity = moles of solute / volume in litter
Number of moles = mass / molar mass
Number of moles = 0.69 g / 56.1 g/mol
Number of moles = 0.0123 mol
Molarity = moles of solute / volume in litter
Molarity = 0.0123 mol / 1.535 L
Molarity = 0.008 M
One mole of CaO neutralize two mole of OH⁻.
0.008 M×2 = 0.016 M
[OH⁻] = 0.016 M
pOH = -log [OH⁻]
pOH = [0.016]
pOH = 1.8
14 = pH +pOH
pH = 14 - pOH
pH = 14-1.8
pH = 12.2
I might be wrong but I think its 2 then 4 then 8

Explanation:
The following are the answers
(1) if the solution is colourless : The answer is B Cr207
(2) If the solution gives no apparent reaction with dilute hydrochloric acid, : The answer is A CO3
(3) if No odour can be detected when a sample of the solution is added drop by drop to a warm solution of sodium hydroxide : The answer is C NH4
(4) If No precipitate is formed when a dilute solution of H2SO4 is added to a sample of the solution : The answer is D ba
