What role does the sun play in the formation of rain

valkas [14]

Not my best subject, but I believe that the heat of the sun evaporates the water from other rain storms that had happened before. Once the water evaporates it gets formed into clouds (rain clouds) and after a while it get heavy or a bit cold so the cloud releases the water it held and the water being dropped is rain. I'm sorry if this is wrong this is all I can remember, but I believe it should be enough for elementary school.

Write a balanced half-reaction for the reduction of dichromate ion to chromium ion in acidic aqueous solution. Be sure to add ph

Serhud [2]

Answer:

The balanced half-reaction for the reduction of dichromate ion to chromium ion in acidic aqueous solution:

$Cr_2O_7^{2-}(aq)+14H^+(aq)+6e^-\rightarrow 2Cr^{3+}(aq)+7H_2O(l)$

Explanation:

The reaction :

$Cr_2O_7^{2-}\rightarrow Cr^{3+}$

Balancing of reaction in an acidic medium:

Step 1: Balance the atoms in the reaction:

$Cr_2O_7^{2-}(aq)\rightarrow 2Cr^{3+}(aq)$

Step 2: Balance oxygen atom by adding water on the side where no oxygen or less oxygen atom is present;

$Cr_2O_7^{2-}(aq)\rightarrow 2Cr^{3+}(aq)+7H_2O(l)$

Step 3: Balance the hydrogen atom by adding hydrogen ions on the side where water is absent:

$Cr_2O_7^{2-}(aq)+14H^+(aq)\rightarrow 2Cr^{3+}(aq)+7H_2O(l)$

Step 4: Now balance charge by adding electrons on the side where more positive charge is present

$Cr_2O_7^{2-}(aq)+14H^+(aq)+6e^-\rightarrow 2Cr^{3+}(aq)+7H_2O(l)$

The balanced half-reaction for the reduction of dichromate ion to chromium ion in acidic aqueous solution:

$Cr_2O_7^{2-}(aq)+14H^+(aq)+6e^-\rightarrow 2Cr^{3+}(aq)+7H_2O(l)$
