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.

<span>They have similar or common ancestor. The similarities inherited from the common ancestor as in the case of homologous organs. In evolutionary biology a group of organisms share a common descent if they have a common ancestor. There are many other examples like in the case of hemoglobin to prove the theory of common ancestor</span>
This is what I found!!! I hope this helps!!!!
Answer:
0.5
Explanation:
2NaCl(s) + 2H2SO4(l) + MnO2(s) → Na2SO4(s) + MnSO4(s) + 2H2O(g) + Cl2(g)
Using ideal gas equation,
PV = nRT
28.7torr
Converting torr to atm,
= 0.0378atm
V = 0.597L
T = 27 °C
= 300 K
a) PV = nRT
(0.0378atm) * (0.597L) = n(0.0821) * (300k)
= 0.000915 mol
moles of water and chlorine = 0.000915 mol
From the above equation, the ratio of water to chlorine = 1 : 2
Therefore, mole of chlorine = 0.000915/2
= 0.000458 mol
mole fraction = moles of specie/moles of all the species present
= 0.000458/0.000915
= 0.5
It would be C. Hope this was helpful! ;)
