Answer:
Hello attached below is the data found in Aleks Data tab
answer :
i) N0
ii) N0
iii) YES , pH of highest solubility = 5
Explanation:
i) For CuBr
solubility does not change with pH hence answer = NO
ii) For MgCl2
solubility does not change with pH hence the answer = NO
iii) For Ba(OH) 2
Solubility does change with pH hence the answer = YES
and the pH at which the highest solubility will occur is = 5
attached below is the reason for the answers given
Answer: -
Organic compounds consisting of only carbon atoms and hydrogen atoms are known as hydrocarbons.
Hydrocarbons are used by us for mainly as a source of energy. Hydrocarbons make up gasoline which is used as fuel in automobiles.
Hydrocarbons depending on the type of unsaturation can be of three types - alkanes, alkenes and alkynes.
In a redox chemical reaction, one species gets reduced and another gets oxidized. Manganese element is reduced in this reaction.
<h3>What is oxidized and reduced?</h3>
In a redox reaction, the increase or decrease in the oxidation number and electrons results in the reduction and oxidation of the chemical species. The oxidation and reduction occur simultaneously in a reaction.
The oxidation number of Mn in permanganate ion was +8 on the left side and decreased to +4 on the right side of the equation. Potassium permanganate is an oxidizing agent that has reduced the manganese ion of the permanganate ion.
Therefore, manganese is reduced.
