sin theta equals to cos theta then the value of sin 2 theta
Here we have to get the effect of addition of 0.25 moles of gas C on the mole fraction of gas A in a mixture of gas having constant pressure.
On addition of 0.25 moles of C gas, the mole fraction of gas A will be
.
The partial pressure of gas A can be written as
=
×P (where
is the mole fraction of gas A present in the mixture and P is the total pressure of the mixture.
The mole fraction of gas A in a mixture of gas A and C is =
and
respectively.
Thus on addition of 0.25 moles of C gas, the mole fraction of gas A will be
.
Which is different from the initial state.
Answer:
A.
Explanation:
A change of position over time.
B is a vector and C is a distance.
The answer is A through transferring or sharing electrons
