Ammonia is made industrially by reacting nitrogen and hydrogen under pressure, at high temperature, and in the presence of a cat
nordsb [41]

Answer:

From 4.0 moles of hydrogen 2.67 moles of ammonia are produced.

Explanation:

Given data:

Number of moles of hydrogen react = 4.0 mol

Number of moles of ammonia produced = ?

Solution:

Chemical equation:

N₂ + 3H₂     →       2NH₃

Now we will compare the moles of hydrogen and ammonia from balance chemical equation.

                          H₂               :              NH₃

                           3                :                2

                           4                :              2/3×4 = 2.67 mol

From 4.0 moles of hydrogen 2.67 moles of ammonia are produced.

What is the molarity of NaOH, if 15g of NaOH is mixed with 600mL?
inn [45]
M(NaOH)=15 g

v=600 ml=0.6 l

n(NaOH)=m(NaOH)/M(NaOH)

C=n(NaOH)/v=m(NaOH)/[M(NaOH)v]

C=15g/[40g/mol*0.6 l]=0.625 mol/l

0.625M



[H⁺]=7.5*10⁻²
pOH=14-pH=14+lg[H⁺]
pOH=14+lg(7.5*10⁻²)=14-1.125=12.875
