SO42- + 2Cr(OH)3 + 4OH- → + 2CrO42- + 3SO32- + 5H2O In the above redox reaction. Use oxidation numbers to identify the element oxidized, the element reduced, the oxidizing agent and the reducing agent.

Reduced species and oxidizing agent: sulfur in the form of sulfate.

Oxidized species and reducing agent: chromium in the form of chromous hydroxide.

Explanation:

Hello!

In this case, for the reaction:

We can see that the oxidation states of sulfur and chromium change from +6 to +4 and +3 to +6 respectively; in such a way, since the oxidized species is the same reducing agent because it undergoes an increase in the oxidation state, we infer that chromium is it as it goes from +3 to +6.

Moreover, since the reduced species is the same oxidizing agent because it undergoes a decrease in the oxidation state, we infer that sulfur is it as it goes from +6 to +4.

Best regards!

hi,

the answer is d.indefinite shape but definite volume, let go oogle u out

hope this !

its first and third is your answer i did the qustion the fourth isnt right
