Answer:

Ba(NO₃)₂ (aq) + H₂SO₄ (aq) → BaSO₄ (s) + 2HNO₃ (aq)

Explanation:

The equation bellow can be explained by the dissociation of each specie:

Ba(NO₃)₂ (aq) → Ba²⁺ (aq) + 2NO₃⁻ (aq)

H₂SO₄ (aq) → 2H⁺ (aq) + SO₄²⁻ (aq)

The reaction will lead to the formation of solid barium sulfate and nitric acid.

If 2.0×10−4 moles of S2O2−8 in 170 mL of solution is consumed in 170 seconds , what is the rate of consumption of S2O2−8?

Ostrovityanka [42]

Answer : The rate of consumption of $S_2O_2^{-8}$ is, $7.0\times 10^{-6}M/s$

Explanation : Given,

Moles of $S_2O_2^{-8}$ = $2.0\times 10^{-4}mol$

Volume of solution = 170 mL = 0.170 L (1 L = 1000 mL)

Time = 170 s

First we have to calculate the concentration.

$\text{Concentration}=\frac{\text{Moles}}{\text{Volume of solution}}$

$\text{Concentration}=\frac{2.0\times 10^{-4}mol}{0.170L}$

$\text{Concentration}=1.2\times 10^{-3}M$

Now we have to calculate the rate of consumption.

$\text{Rate of consumption}=\frac{\text{Concentration}}{\text{Time}}$

$\text{Rate of consumption}=\frac{1.2\times 10^{-3}M}{170s}$

$\text{Rate of consumption}=7.0\times 10^{-6}M/s$

Thus, the rate of consumption of $S_2O_2^{-8}$ is, $7.0\times 10^{-6}M/s$

Answer:

The least similar to a real gas found in the environment would be B.

Explanation:

Standard Ambient Temperature/Pressure (SATP) is at 298.15K and 101.3kPa. It describes standard conditions and is often used for measuring gas density and volume using the Ideal Gas Law. The values least similar to theses ones would be the least similar in the gases in the environment.
