Furkat [3]

Answer:

HNO₃ (aq) —> H⁺ (aq) + NO₃¯ (aq)

Explanation:

From the question given above

HNO₃ + H₂O —> ?

Nitric acid, HNO₃ reacts with water, H₂O to form aqueous solution of nitric acid as illustrated below:

HNO₃ + H₂O —> HNO₃ (aq)

Nitric acid is a strong acid and, so will ionised completely when dissolved in water. This is illustrated below:

HNO₃ (aq) —> H⁺ (aq) + NO₃¯ (aq)

Arrange the following alkyl bromides in order from most reactive to least reactive in an SN2 reaction: 1-bromo-2-methylbutane, 1
xxMikexx [17]
Primary alkyl halides tend to undergo the SN2 reaction mechanism in nucleophilic substitution since there is less steric hindrance for nucleophilic attack and the carbocations that they form are not as stable as those formed from tertiary alkyl halides.

A sample of seawater contains 1.3 g of calcium ions in 3,100 kg of solution. what is the calcium ion concentration of this solut
IrinaVladis [17]

A unit of ppm has an acronym of parts per million. The equivalent units of ppm is therefore mg/L and mg/kg. So the ppm is:

mass Ca+ = 1.3 g = 1300 mg

 

ppm = 1300 mg / 3100 kg

<span>ppm = 0.42 ppm</span>

Answer:

2.1 × 10⁻¹ M

2.0 × 10⁻¹ m

Explanation:

Molarity

The molar mass of aniline (solute) is 93.13 g/mol. The moles corresponding to 3.9 g are:

3.9 g × (1 mol/93.13 g) = 0.042 mol

The volume of the solution is 200 mL (0.200 L). The molarity of aniline is:

M = 0.042 mol/0.200 L = 0.21 M = 2.1 × 10⁻¹ M

Molality

The moles of solute are 0.042 mol.

The density of the solvent is 1.05 g/mL. The mass corresponding to 200 mL is:

200 mL × 1.05 g/mL = 210 g = 0.210 kg

The molality of aniline is:

m = 0.042 mol/0.210 kg = 0.20 m = 2.0 × 10⁻¹ m
