Use the reaction N2(g) + 3H2(g) 2NH3(g) to answer the following questions
kumpel [21]

Answer:

Explanation:

a ) If N₂(g) and 3H₂(g) is added to the system , 2 moles of additional  ammonia will be produced .

b ) If pressure is decreased , less amount of ammonia will be formed, because forward reaction reduces the pressure. So, reaction will take place in reverse direction.

c ) Keq = [ NH₃ ] ² / [ N₂ ] [ H₂]³

d ) Substituting the given values in the equation ,

Keq = [ 6M ] ² / [ 3M] [ 4M]³

= 36 / 3 x 64 M⁻²

= 18.75 x 10⁻² M⁻² .

If the pH of the solution is 10, what is the [OH-] concentration?
swat32

Answer:

1×10^{-4}M

Explanation:

To solve this, you will need to do multiple steps.

Firstly, you will have to convert to pOH from pH, which is done by simply subtracting 14-10 to get a pOH of 4.

Then, use the following formula to calculate the [OH-} concentration:

[OH-]= 10^{-pOH}

When converted to Scientific Notation<u>,</u> you get a resulting answer of

<u>1×</u>10^{-4}M<u>.</u>
