True

when a substance is impure, it boils over a range of temperature rather than a specific temperature

I believe the correct answer is true. <span>A substance which melts/boils at a fixed temperature is a pure substance. This is because the substance is homogeneous throughout that the properties as well would be uniform. Hope this answers the question. Have a nice day.</span>

28 Which compound yields H + ions as the only positive ions in an aqueous solution?

MrMuchimi

Answer: (4) $CH_3COOH$

Explanation:-

According to Arrhenius concept, a base is defined as a substance which donates hydroxide ions $(OH^-)$ when dissolved in water and an acid is defined as a substance which donates hydronium ions $(H_3O^+)$ in water.

1. $KOH$ is a strong electrolyte and thus dissociate in water. $KOH\rightarrow K^++OH^-$

2. $CH_3OH$ is a non electrolyte and thus do no dissociate in water.

$CH_3COOH\rightarrow no reaction$

3. $NaOH$ is a strong electrolyte and thus dissociate in water.

$NaOH\rightarrow Na^++OH^-$

4. $CH_3COOH$ is a weak electrolyte and thus partially dissociate in water.

$CH_3COOH\rightleftharpoons CH_3COO^-+H^+$

Explanation:

We have the following chemical reaction:

MnO₂ + HCl → MnCl₂ + H₂O + Cl₂

To balance the chemical equation the number of atoms of each element entering the reaction have to be equal to the number of atoms of each element leaving the reaction, in order to conserve the mass.

So the balanced chemical equation is:

MnO₂ + 4 HCl → MnCl₂ + 2 H₂O + Cl₂
