For the answer to the question above,
1∙5µm² = ? m²
1m * 1m = 1m² But 1m = 1,000,000µm = 1x 10^6µm 1x10^6µm * 1x10^6µm = 1m² 1x 10^12µm² = 1m² (Now, try dividing both sides by 1x10^12). 1x10^12µm² /(1x10^12) = 1m² /(1x10^12) 1µm² = 0∙000 000 000 001 m² (multiply both sides by by 1∙5). 1∙5µm² = 0∙000 000 000 0015 m²

1∙5µm² = 1∙5x 10^-12 m²
I hope this helps

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.
