I hope this helps. If you’d like further explanation please let me know.
CO₂, will have the lowest boiling point among the following ,therefore option (d) is correct.
<h3>What do you mean by the boiling point?</h3>
The temperature at which liquid vapor pressure equals atmospheric pressure is referred to as boiling point.
The boiling point is defined as the temperature at which a liquid’s saturated vapor pressure equals the atmospheric pressure surrounding it.
The boiling point for any material is the temperature point at which the material transforms into its form.
The one with the lowest boiling point has the weakest intermolecular forces.
CO₂, will have the lowest boiling point among the following ,therefore option (d) is correct.

Answer:
[NaCl(aq)] = 0.25M
Explanation:
Molarity = moles solute / volume of solution in liters
moles NaCl in 29.25 grams = 29.25g/58g·mol⁻¹ = 0.5043 mole
Molarity = 0.5043 mole NaCl / 2 Liters = 0.2555M ≅ 0.25M (2 sig-figs)
Answer:
16.8128 grams of sodium azide is needed
Explanation:
2NaN3 = 2Na + 3N2
molar mass of NaN3 =
molar mass of N2
moles of N2 =
moles=mass/R.F.M
16.55÷42 = 0.3940
mole ratio=
2NaN3 : 3N2
3 = 0.3940
2=?
Mass of sodium azide =64×0.2627
=16.8126
The statement would be considered a law.
