In chemistry, a solution is a homogeneous mixture composed of two or more substances. In such a mixture, a solute is a substance dissolved in another substance, known as a solvent.
Answer:
Plants need energy from the sun, water from the soil, and carbon from the air to grow. Air is mostly made of nitrogen, oxygen, and carbon dioxide. So how do plants get the carbon they need to grow? They absorb carbon dioxide from the air.

I believe the correct answer from the choices listed above is the last option. Lactase and carbonic anhydrase are examples of enzymes. Lactase is an enzyme produced by a lot of organisms. Carbonic anhydrases, on the other hand, is a family of enzymes that catalyze the rapid interconversion of CO2 and H2O to bicarbonate.
Answer:
Conc of Q at Equilibrium 2.1 × 10⁻³ mol/dm³
Ksp = 1.57 × 10⁻¹² mol/dm³
Explanation:
The Solubility of the Ionic compound is given by s
where s = 7 × 10⁻⁴ mol/dm³
solubility equation is given as follows
XQ₃(s) ⇄ X³⁺(aq) + 3Q⁻(aq)
s s 3s
let the concentration of each be s
The concentration of Q = 3s
⇒ [Q] = 3 × 7 × 10⁻⁴ mol/dm³
⇒ [Q] = 2.1 × 10⁻³ mol/dm³
hence,
Ksp = [X³⁺][Q⁻]³
Ksp = [s][3s]³
Ksp = [7 × 10⁻⁴ ][2.1 × 10⁻³]³
Ksp = 1.57 × 10⁻¹² mol/dm³
