A solution containing 1.0 M NiCl2 and 1.0 M SnBr2 undergoes electrolysis by passing a current between two platinum electrodes. W
scoray [572]

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.

How many moles of calcium chloride are theoretically produced for the following reaction given we have 2.6 moles of HCl and 1.4
Georgia [21]

Answer : The number of moles of calcium chloride theoretically produced are, 1.3 moles.

Explanation : Given,

Moles of HCl = 2.6 moles

Moles of Ca(OH)_2 = 1.4 moles

Now we have to calculate the limiting and excess reagent.

The given balanced chemical reaction is:

2HCl+Ca(OH)_2\rightarrow 2H_2O+CaCl_2

From the balanced reaction we conclude that

As, 2 mole of HCl react with 1 mole of Ca(OH)_2

So, 2.6 moles of HCl react with \frac{2.6}{2}=1.3 moles of Ca(OH)_2

From this we conclude that, Ca(OH)_2 is an excess reagent because the given moles are greater than the required moles and HCl is a limiting reagent and it limits the formation of product.

Now we have to calculate the moles of CaCl_2

From the reaction, we conclude that

As, 2 mole of HCl react to give 1 mole of CaCl_2

So, 2.6 moles of HCl react to give \frac{2.6}{2}=1.3moles of CaCl_2

Therefore, the number of moles of calcium chloride theoretically produced are, 1.3 moles.

Write a balanced molecular equation for the reaction of<br> sodiummetal with water.
9966 [12]

Answer:

Na + H₂O → NaOH + 1/2 H₂

Explanation:

When sodium reacts with water, it forms sodium hydroxide and molecular hydrogen. The unbalanced equation is:

Na + H₂O → NaOH + H₂

We have to balance this equation so it obeys the law of conservation of mass. We have 1 atom of Na on each side and 1 atom of O on each side, so these elements are balanced. However, we have 2 atoms of H on the left side and 3 atoms of H on the right side. The easiest way to balance the H without modifying the other elements is by making 1/2 the stoichiometric coefficient of H₂.

Na + H₂O → NaOH + 1/2 H₂
