Answer:
Option (C) 1 × 10^−12
Explanation:
Step 1:
Data obtained from the question include:
[H+] = 1x10^−2
[OH−] =?
Step 2:
Determination of [OH−] . This is illustrated below:
[H+] x [OH−] = 1x10^-14
1x10^−2 x [OH−] = 1x10^-14
Divide both side by 1x10^−2
[OH−] = 1x10^-14 / 1x10^−2
[OH−] = 1x10^-12
Therefore, the [OH−] of the solution is 1x10^-12
Answer:
Magnesium and calcium belong to the second group i. e. alkaline earth metals. They are known as earth metals because they are extracted from the earth. They are very reactive elements. Their reactivity increases when we go from top to bottom because the outermost electrons goes farther from the nucleus i. e. atomic radius increases so less energy is needed for its removal.
