Answer:
0.2208 is the equilibrium constant,.
Explanation:
Equilibrium constant is defined as ratio of concentration of products to the concentration of reactants raised to the power equal to their stoichiometric coefficients in balanced chemical equation. It is expressed as
If the equilibrium is in gaseous phase then instead of concentration take partial pressure of each compound.The It is expressed as .
Partial pressure of the
Partial pressure of the
Partial pressure of the
The expression of an equilibrium constant is given as:
I used a graphing calculator to do perform this calculation. The answer is 3.92
Answer : The correct option is, (E) 6 moles.
Explanation : Given,
Moles of nitrogen = 2 moles
The given balanced chemical reaction is:
From the balanced chemical reaction we conclude that,
As, 1 mole of nitrogen gas react with 3 moles of hydrogen gas
So, 2 mole of nitrogen gas react with moles of hydrogen gas
Therefore, the number of moles of hydrogen gas needed to react with 2 moles of nitrogen gas is, 6 moles.
Answer:
C
Explanation:
Because together all of the electrons create a negative charge.That balances the positive charge of the protons in the atomic nucleus.
