If 19.7 g of AlI3 is actually produced, what is the percentage yield? 2 Al + 3 I2 → 2 AlI3

1 answer:

8 0

The formula actual yield / theoretical yield is used to calculate the percent yield of a reaction. This value is a measure of how much product is produced relative to the what is supposed to be produced. It seems that the given in the problem is incomplete so we cannot really give a specific value.

Using the redox reaction below determine which element is oxidized and which is reduced. 4nh3 + 3ca(clo)2 → 2n2 + 6h2o + 3cacl2

lys-0071 [83]

The oxidation number of elements in equation below are,

4NH₃ + 3Ca(ClO)₂ → 2N₂ + 6H₂O + 3CaCl₂

O.N of N in NH₃ = -3
O.N of Ca in Ca(ClO)₂ and CaCl₂ = +2
O.N of N in N₂ = 0
O.N of Cl in Ca(ClO)₂ = +1
O.N of Cl in CaCl₂ = -1

Oxidation:
Oxidation number of Nitrogen is increasing from -3 (NH₃) to 0 (N₂).

Reduction:
Oxidation number of Cl is decreasing from +1 [Ca(ClO)₂] to -1 (CaCl₂).

Result:
N is oxidized and Cl is reduced.
