The ways in which ammonia can be identified is mentioned in below pointers.

<h3>What is Ammonia ?</h3>

Ammonia is a compound of nitrogen and hydrogen with the formula NH3.

A stable binary hydride, and the simplest pnictogen hydride.

Ammonia is a colourless gas with a distinct pungent smell.

Biologically, it is a common nitrogenous waste,

Three ways in which ammonia gas can be identified is:

  • It has a sharp characteristic odor.

  • When a glass rod dipped in HCl is brought in contact with the gas white color fumes of ammonium chloride are formed.

  • It turns moist red litmus blue, moist turmeric paper brown, and phenolphthalein solution pink.

3. At STP, how many liters of oxygen gas are required to react completely with 3.2 x 10^22
Mrrafil [7]

The volume of oxygen required to react with 3.2 * 10²² molecules of hydrogen is 0.56 L.

<h3>What is stoichiometric law?</h3>

The stoichiometric law has been given as the representation of the moles of product and reactant in a chemical reaction are represented by the stoichiometric coefficient.

It has been known that 1 mole of a compound has 6.023 * 10²³ molecules. Thus, the moles of hydrogen gas equivalent to 3.2 * 10²² molecules has been:

6.023 * 10²³ molecules = 1 mole

3.2 * 10²² molecules = 1/6.023 * 10²³ * 3.2 * 10²² moles

3.2 * 10²²  molecules = 0.05 moles

Thus, the moles of hydrogen gas available is 0.05 moles.

From the stoichiometric law, according to the balanced chemical equation,

2 moles of hydrogen requires = 1 moles of oxygen

0.05 moles of hydrogen requires = 1/2 * 0.05 moles oxygen

0.05 moles of hydrogen requires =  0.025 moles oxygen

Thus, the moles of oxygen required is 0.025 moles. At STP, a mole of gas been equivalent to 22.4 L . Thus, the volume of 0.025 moles oxygen has been:

1 mole = 22.4 L

0.025 moles = 22.4 * 0.025 L

0.025 mole = 0.56 L

Thus, the volume of oxygen required to react with 3.2 * 10²² molecules of hydrogen is 0.56 L.
