Answer:
Oxidation can be defined in many ways:
In terms of electron, <em>Oxidation</em> can be defined as loss of electrons by an atom or ion or a molecule during a reaction.
In terms of oxygen transfer, <em>oxidation</em> maybe defined as a substance that gains oxygen or loses hydrogen.
It can also be defined as a process in which a carbon atom gains bond to more electronegative atom such as oxygen.
It will double

P = pressure of the gas
n= number of moles of the gas
V= volume of the gas
R = the gas constant
T= absolute temperature of the gas
If V is halved when n and T remain the same
Answer:
Decreases
Explanation:
The temperature decreases when latitude increases.
Answer: option C) II < III < I
i.e [OH−] < [H3O+] < I
Explanation:
First, obtain the pH value of I and II, then compare both with III.
For I
Recall that pH = -log (H+)
So pH3O = -log (H3O+)
= - log (1x10−5)
= 4
For II
pOH = - log(OH-)
= - log(1x10−10)
= 9
For III
pH = 6
Since, pH range from 1 to 14, with values below 7 to be acidic, 7 to be neutral, above 7 to be alkaline: then, 9 < 6 < 4
Thus, the following solutions from least acidic to most acidic is II < III < I
