The correct answer is NH₄Cl.
With the increase in temperature, endothermic reactions are favored. The dissolution of NH₄Cl in water is an example of an endothermic reaction. When the temperature is increased more dissolution of the salt takes place, thus, the solubility of the salt increases.
Hence, it can be said that NH₄Cl will exhibit the greatest change in the solubility per 100 g solvent with an elevation in temperature.
Tin and Hydrofluoric Acid reacts as shown,
<span> Sn + 2 HF </span>→ SnF₂<span> + H</span>₂
According to Equation,
40.02 g (2 Moles) HF Required = <span>1 Mole of Sn for complete Reaction
So,
40 g of HF will require = X Moles of Sn
Solving for X,
X = (40 g </span>× 1 Mole) ÷ 40.02 g
X = 0.999 Moles ≈ 1 Mole
Result:
40 g of HF requires 1 Mole of Tin (Sn) for complete Reaction to produce SnF₂ and H₂.

Everything has 1 except for the Nitrate ion in D, which has 2
Marble has the same mass but a different volume so its less dense
Answer: The value of equilibrium constant for the given reaction is,
Explanation:
The given chemical equation is:
;
We need to calculate the equilibrium constant for the chemical equation, which is:
;
If the equation is revered then the equilibrium constant will be the reciprocal of the reaction.
If the equation is half then the equilibrium constant will be square-root of the reaction.
The value of equilibrium constant for the given reaction is:
Hence, the value of equilibrium constant for the given reaction is,
