Explanation:

Equation of reaction

BaSO₄ + H₂SO₄ → Ba(HSO₄)₂

From the above equation of reaction, it is evident that there are 2 atoms in the product side of the reaction which is only logical because every chemical reaction obey the law of conservation of mass which states that matter can neither be created nor destroyed but can changed from one form to another.

In the reactant side, we have 2 atoms of S from the two reactants coming together.

One sulfur atom from BaSO₄ and the other from H₂SO₄. So therefore, only 2 sulfur can be produced since the reaction has to observe law of conservation of matter

For fish to survive in your aquarium, you need to have a saturated solution of oxygen in the water. Suppose your aquarium holds

solmaris [256]

Answer:

The mass of oxygen needed to be pumped in the aquarium is 10 g

Explanation:

Here the value of the degree of solubility of oxygen in water is sought

The solubility of oxygen in fresh water is approximately 1.22 × 10⁻³ mol·dm⁻³ which is equivalent to approximately 40 mg/L

The volume of water the aquarium holds = 250 L

The mass of oxygen required = The solubility of oxygen in water × (The volume of water in the aquarium)

Therefore, the mass of oxygen needed to be pumped in the aquarium = 40 mg/L × 250 L = 10,000 mg

1,000 mg = 1 g

∴ 10,000 mg = 10 g

The mass of oxygen needed to be pumped in the aquarium = 10,000 mg = 10 g.

Igoryamba

Answer:

The reaction will proceed to the left to attain equilibrium.

Explanation:

The question is missing but I guess it must be about <em>how the reaction will proceed to attain equilibrium.</em>

First, we have to calculate the partial pressures using the ideal gas equation.

$pP_{4}=\frac{2.50mol\times (0.08206atm.L/mol.K)\times 673K}{25.0L} =5.52atm$

$pP_{2}=\frac{1.50mol\times (0.08206atm.L/mol.K)\times 673K}{25.0L}=3.31atm$

Now, we have to calculate the reaction quotient (Qp).

$Qp=\frac{pP_{2}^{2}}{pP_{4}} =\frac{3.31^{2} }{5.52} =1.98$

Since Qp > Kp, the reaction will proceed to the left to attain equilibrium.
