Answer: There will be 131.3 tons of that will be generated.
Explanation : We have the data as 72 tons of ,
is 101 tons and
as 38 tons.
Conversion of 1 ton to kg will be approximately 907.2 Kg
We have to convert the given data of tons into kg for all;
So, moles of = (72 tons X 907.2 Kg/ton X 1000 g/Kg) / (34.082 g/ mol) = 1.916 X
moles
Now, moles of = (101 tons X 907.2 Kg/ton X 1000 g/Kg) / (32 g/mol) = 2.80 X
moles
And, = (38 tons X 907.2 Kg/ton X 1000 g/Kg) / (18.016 g/mol)
= 1.03 X moles
Now, we have to calculate the moles of
so, 1.916 X moles / 2 moles of
= 958 X
Now, for ;
So, 2.80 X moles / 3 moles of
= 933.3 X
moles
Here, we can see that is acting as a limiting reactant.
Now, moles of = 2.80 X
X (2 moles of
/ 3 moles of
) = 1.86 X
Now converting this into mass,
Mass = Moles X Molar Mass
Mass = 1.86 X X (64.066 g/mol X
kg/g) X (1 ton / 907.2 Kg)
= 131.3 tons of

Answer:
(4)KBr(aq)
Explanation:
A mixture is an impure substance made up of two or more substances that are joined together. Their composition is indefinite and not easily represented by a simple chemical formula.
KBr is a mixture because it made up of an aqueous solution of KBr. This suggests that the substance KBr is placed inside water.
Here, we have two states of matter which is the solid and the liquid coming together.
As with both mixtures, they can be separated by physical means, KBr aqueous solution can also be done this way.
