d.
125%
e.
1.25%
6. Cu₂Hgl4 is prepared according to the equation 2 Cul + Hgl₂ → Cu₂Hgl4 When 2.00 g of each reactant are used,
which one is the limiting reactant?
a.
Both reactants are limiting
b.
This reaction has no limiting reactant
C.
Cul
d. Hgl₂
e. Cu₂Hgl4

Respuesta :

The percent yield is given by the actual and the theoretical yield. The percent yield of the 2.73 gm compound is 80.3%. Thus, option b is correct.

What is the percent yield?

The percent yield is the ratio of the actual yield to the theoretical yield. It is calculated as:

% Yield = Actual yield ÷ Theoretical yield × 100%

= 2.73 ÷ 3.84 × 100%

= 71.09 %

As the closest number to 71.09 is 80.3% the percent yield will be 80.3%.

There is no limiting reagent in the reaction between the copper iodide and mercury iodide as the moles of the reactants and the products are in equal quantity.

Hence, option b. there is no limiting reagent in this reaction.
