Answer:
Sn2+ (aq) + 2e- → Sn(s) ℰ° = -0.14 V
Explanation:
A close look at all the options shows that the most feasible first reaction is the reduction of tin II ion to ordinary metallic tin.
Given the two half cells, nickel is oxidized in one half cell to Ni II while in the second half cell, tin II ion is reduced to metallic tin. The platinum electrodes simply act as electron conduits in the cell.
The coriolis force caused by the Earth's rotation is what gives winds within high-pressure systems their clockwise circulation in the northern hemisphere (as the wind moves outward and is deflected right from the center of high pressure) and counterclockwise circulation in the southern hemisphere (as the wind moves ...
There are four atoms of fluorine present
Answer:
5.85 gm.
Explanation:
We know that,
Normality =<u> Molarity × Molecular </u><u>weight</u>
Equivalent weight
Since molecular weight of NaCl= equivalent weight = 23+35.5 =58.5
Normality of NaCl= molarity=2
Now,
Normality= <u>weight</u><u> </u><u>in</u><u> </u><u>gram</u><u> </u><u>×</u><u>1000</u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u>
Volume ×equivalent weight
Weight in gram is given by,
<u>=</u><u>Normality × Volume × equivalent </u><u>weight</u>
1000
= <u>2× 50 × 58.</u><u>5</u>
1000
=5.85 gm.
