Answer:
<h3>Right answer is: ( a) chalk powder remains suspended in water.</h3>
Explanation:
Filtration is the technique used to separate suspended solute particles from a solution . The chalk powder remains suspended in the solution and can easily be filtered through a filter paper , the chalk powder can be collected on the filter paper and clear solvent is collected as the filtrate.
True, because the large covalent molecules would combine with the others
The answer is (A).
Hope this helps :).
Answer:
pH = 11, The solution is Basic.
Explanation:
We know that;
[OH-] [H+] = 1 × 10^-14
we are given; [OH-] as 1 x 10^ -3 M
Therefore, we can get the [H+] by;
[H+] = 1 × 10^-14/[OH-]
= 1 × 10^-14 M/1 x 10^ -3 M
= 1 × 10^-11 M
But; pH = - log [H+]
Thus,
pH = - log (1 ×10^-11 M)
= 11
pH = 11, which means the solution is basic.
