0.7 mol of H⁺ ions are present in 2.8 l of 0.25 m hydrobromic acid solution.

Hydrobromic acid is a strong acid, we can assume that all acid molecules dissociate completely to yield H+ ions and dissociated anion.

<h3>The equation for the dissociation of HBr :</h3>

Hbr <em>(s) → </em>H⁺ <em>(aq) </em>+ Br⁻<em> (aq)</em>

moles H⁺ = ( $2800ml$ ) ( $\frac{1L}{1000ML}$ ) ( $\frac{0.25 mol Hbr}{L}$ ) ( $\frac{1 mol H}{1 mol Hbr}$ )

= 0.7 mol

Therefore, 0.7 mol of H⁺ ions is present.

For the reaction: N2(g) + 2 O2(g) ⇌ 2 NO2(g), Kc = 8.3 × 10-10 at 25°C. What is the concentration of N2 gas at equilibrium when

KATRIN_1 [288]

Answer: Concentration of N₂ is 4.8. $10^{9}$ M.

Explanation: $K_{c}$ is a constant of equilibrium and it is dependent of the concentrations of the reactants and the products of a balanced reaction. For

N2(g) + 2 O2(g) ⇄ 2 NO2(g)

$K_{c}$ = $\frac{[NO2]^{2} }{[N2][O2]^{2} }$

From the question concentration of NO2 is twice of O2:

[NO2] = 2[O2]

Substituting this into $K_{c}$ :

$K_{c}$ = $\frac{[2O2]^{2} }{[N2][O2]^{2} }$

8.3. $10^{-10}$ = $\frac{4O2^{2} }{[N2].O2^{2} }$

[N2] = $\frac{4O2^{2} }{8.3.10^{-10}.O2^{2} }$

[N2] = $\frac{4}{8.3.10^{-10} }$

[N2] = 4.8. $10^{9}$

The concentration of N2 in the equilibrium is [N2] = 4.8. $10^{9}$ M.

A solution is prepared by dissolving 15.0 g of NH3 in 250.0 g of water. The density of the resulting solution is 0.974 g/mL. The

iVinArrow [24]

Answer:

[NH₃] → 3.24 M

Explanation:

Our solute: Ammonia

Our solvent: Water

Solution's mass = Mass of solute + Mass of solvent

Solution's mass = 15 g + 250 g = 265g

We use density to determine, the volume.

D = mass /volume → Volume = m / D → 265 g /0.974 g/mL = 272.07 mL.

We convert the mL to L → 272.07 mL . 1L /1000mL = 0.27207 L

To determine molarity we need the moles of solute in 1 L of solution.

Moles of solute are: 15g / 17g/mol = 0.882 moles

[NH₃] = 0.882mol /0.27207 L → 3.24 M
