it is defined as the ratio of moles of one substance to the moles of another substance in a balanced equation. To determine the mole ratio between two substances, all you need to do is look at the balanced equation for the coefficients in front of the substances you are interested in.
The balanced equation is
2SO
2
+
O
2
→
2SO
3
The statement about the formation of the solar system that
are true and in a correct order are Gravitational force held the newly formed
planets around the sun; small planetary objects formed; hydrogen and helium
became concentrated in the outer solar system to form the outer planets. The answer
is letter D.
These are known as adaptions which causes evolution
Answer:
C. 101.5°C
Explanation:
The computation of the boiling point of a solution is shown below:
As we know that
where,
i = Factor of Van’t Hoff i.e 2KBr
K_b = Boiling point i.e 0.512° C
m = molality 
Now place the values to the above formula
So, the boiling point is
After solving this, the t is
= 100° C + 1.536° C
= 101.536° C
Hence, the correct option is C.
