The theoretical yield of Cl2 from certain starting amounts of MnO2 and HCl was calculated as 60.25 g and 65.02 g, respectively.

user100 [1]

Answer:

c 43.38 g

Explanation:

The reaction between MnO2 and HCl can be represented by the following balanced equation:

MnO2 + HCl ---> Cl2 + MnCl2 + H2O

From the balanced equation, the theoretically required molar ratio of MnO2 to HCl is 1:1, therefore the yields would have been expected to be equal.

For the fact that HCl gives a higher yield (65.02g) than MnO2 (60.25g) according to the problem statement, HCl should be in excess, while the limiting reagent should be MnO2 .

Thus, the theoretical yield of Cl2 will be 60.25 g.

By definition, the percentage yield is given by

% Yield = (Actual Yield) / (Theoretical Yield),

This can be simplified to

Actual Yield = % Yield * Theoretical Yield

Plugging in the given values we have

Actual Yield = 72% * 60.25 = 43.38 g

How many different substituents are required on a carbon atom for it to be chiral?

zheka24 [161]

Four different substituents are required on a carbon atom for it to be chiral.

<h3>What is Chiral Carbons ?</h3>

The carbon atom which is attached with four different types of group of atoms or atoms is called Chiral carbon. Chiral molecules are non superimposable on their mirror images. Chiral carbon is also called asymmetric carbon.

Example:

$Br - \underset{H} {\underset{|} {\overset{CH_3} {\overset{|}{C}}}} - Cl$

In the above example we can see that carbon atom has 4 different group attached with it that is Br, Cl, H, CH₃.

Thus from the above conclusion we can say that Four different substituents are required on a carbon atom for it to be chiral.
