I think it’s C lol sorry if I’m wrong :((
Explanation:
The amount of precipitate produced will be proportional to the amount of NH₃ reacted with water to produce NH₄OH.
<h3>What is precipitate?</h3>
Precipitates are the crystal type formation, when the solute is no more dissolving in the solvent.
Imagine mixing 1 tablespoon of Epsom salt with 2 cups of ammonia, the reaction is
2NH₃ + MgSO₄ + 2H₂O → Mg(OH)₂ + (NH₄)₂SO₄
The amount of precipitate produced will be proportional to the amount of NH₃ reacted with water to produce NH₄OH.

Answer:
Approximately , assuming that this gas is an ideal gas.
Explanation:
Look up the standard room temperature and pressure: and .
The question states that the volume of this gas is .
Convert the unit of all three measures to standard units:
.
.
.
Look up the ideal gas constant in the corresponding units: .
Let denote the number of moles of this gas in that . By the ideal gas law, if this gas is an ideal gas, then the following equation would hold:
.
Rearrange this equation and solve for :
.
In other words, there is approximately of this gas in that .
Polar covalent bonds are between atoms with different electronegativities, whereas nonpolar covalent bonds are between atoms with the same electronegativity.
This means that HCl is a polar covalent bond, whereas H2 is a nonpolar covalent bond.
