Question

Ammonia is an important compound used in the production of frertilizer. Below is the chemical equation for producing ammonia from nitrogen and hydrogen

N2+3H2->2NH2

Fill in the blanks with the appropriate numbers for this equation:
___molecule(s) of nitrogen and ___ molecule(s) of hydrogen react with each other to form __ molecule(s) of ammonia.

Answer 1

`6.022 * 10^(23)` molecule(s) of nitrogen and
`1.8066 * 10^(24)` molecules of hydrogen react with each other to form
`1.2044 * 10^(24)` molecules of ammonia.

Step-by-step explanation:

Given:

The chemical equation for producing ammonia from nitrogen and hydrogen

`N_(2)+3 H_(2) \rightarrow 2 N H_(2)`

1 mole of nitrogen gets reacted with 3 moles of hydrogen in order to form 2 moles of ammonia.

One mole =
`6.022 * 10^(23)` (Applicable to the substances like ions, molecules, or atoms). This specified number is called as Avogadro's constant or number. This idea helps us to convert between the number of particle and mass.

Therefore, when dealing this with the given chemical equation,

1 mole of nitrogen =
`1 * 6.022 * 10^(23)=6.022 * 10^(23) \text { molecule }`

2 moles of ammonia =
`2 * 6.022 * 10^(23)=12.044 * 10^(23)=1.2044 * 10^(24) \text { motecules }`

3 moles of hydrogen =
`3 * 6.022 * 10^(23)=18.066 * 10^(23)=1.8066 * 10^(24) \text { molecules }`
