Answer:
5.64
Explanation:
We are given;
- The concentration of H+ ions as 2.3 x 10^-6 M
We are required to get the pH
- pH is given by getting the negative logarithm of hydrogen ion concentration.
- That is; pH = -log [H+]
Therefore;
pH = - log [2.3 x 10^-6 M]
= 5.638
= 5.64
Hence the pH of the solution is 5.64
Answer:
1.0798 × 10^2kg
Explanation:
1 mg = 1 × 10-6 kg therefore we can multiply 10798 by 1 × 10-6 we will get the amount of kg.
10798 × (1 × 10-6) = 1.0798 × 10^2kg
Boiling-point<span> elevation describes the phenomenon that the </span>boiling point<span> of a liquid (a </span>solvent<span>) will be higher when another compound is added, meaning that a </span>solution has<span> a higher </span>boiling point<span> than </span>a pure solvent<span>. This happens whenever a non-volatile solute, such as a salt, is added to </span>a pure solvent<span>, such as water.
So the correct answer is C.</span>
