Answer:

68 grams is the maximum amount of KCl that can be dissolve in 200 g of water.

Explanation:

Let the maximum amount of KCl dissolved in water be x

Solubility of KCl in water = 34g /100 g

This means that 34 g of KCl can be dissolved in 100 g of water at 20°C

Maximum amount of KCl dissolved in 1 g of water = $\frac{34}{100} g$

Maximum amount of KCl dessolbved in 200 g of water :

$\frac{34}{100}\times 200=68 g$

68 grams is the maximum amount of KCl that can be dissolve in 200 g of water.

Which best describes an oxidizing agent?

stellarik [79]

Answer:B) a reactant that undergoes reduction

Explanation:

Oxidation reaction is defined as the reaction in which a substance looses electrons. The oxidation state of the substance increases during oxidation.

$M\rightarrow M^++e^-$

Reduction reaction is defined as the reaction in which a substance gains electrons. The oxidation state of the substance gets reduced during reduction.

$N^++e^-\rightarrow N$

Overall reaction: $M+N^+\rightarrow M^++N$

The substance M which itself gets oxidized, reduces other and is called as reducing agent. The substance N which itself gets reduced, oxidizes other and is called as oxidizing agent.
