Answer : Below are three ways described in brief for improving the quality of indigenous soap.
1) Add virgin coconut oil which serves as a softener and betel leaf extract. It is used to improve the quality of soap as an antimicrobial agent.
2) Add activated charcoal black granules or powder to the soap, it removes maximum dirt from the skin.
3) Adding a filler which will increase the shelf life of usage of the soap will also improve its quality.
On a Space shuttle, LiOH Is used to absorb CO2 to produce LiHCO3
LiOH + CO2 === LiHCO3
Now
58g of CO2 produces 79.3g of LiHCO3
This is the Actual Yield.
Recall
% Yield = Actual yield/Theoretical yield x100
NOW
We have to find the theoretical yield
From the equation of reaction
Now 58g of CO2 reacted
Converting to Moles
mole = Mass/Molar Mass
Molar mass of CO2=44g/mol
Mole = 58/44
=1.318moles of CO2
From the equation Of Reaction.
1 mole of CO2 reacts and Produces 1 mole of LiHCO3
Since their Mole ratio is 1:1
An Equal amount of LiHCO3 will be produced.
So 1.318moles of LiHCO3 will be produced.
Convert this mole to Mass
Mole =Mass/Molar Mass
Mass = Mole x Molar Mas
Molar Mass of LiHCO3 =68g/mol
Mass = 1.318 x 68
Mass = 89.62g.
This is the theoretical Yield.
% yield = 79.3/89.62 x 100
= 88.48%.
