Answer:Pressure of NH3 increases at the rate of 160torr/hr
Explanation:
According to the equation below
N2H4 (g) + H2 (g) ==> 2 NH3 (g)
It shows that 1mol of N2H4 will gives 2mol of NH3
Therefore, if the partial pressure rate of N2H4 is 80torr/hr, the partial pressure of NH3 increases by 2×80=160torr/hr
Answer:
the answer is C
Explanation:

i is vant Hoff factor
For NaCl vant Hoff factor is 2( Actually 1.9)
Answer:
The movement of substances may occur across a semi‐permeable membrane (such as the plasma membrane). A semi‐permeable membrane allows some substances to pass through, but not others.
Explanation:
The standard state of the elements Nitrogen and Oxygen are N2 and O2, knowing that they are diatomic elements. With that piece of information, the unbalanced equation for the formulation of NO2(g) should be as follows -
N2 + O2 ---> NO2
And if you include their states -
N2 ( g ) + O2 ( g ) ---> NO2 ( g )
To balance this chemical equation consider the number of reactants and products on other side of the equation. If you were to include a coefficient of one - half with respect to N2 on the reactant side, it would balance the reactants and products -
