When a mixture containing cations of Analytical Groups I–III is treated with H2S in acidic solution, which cations are expected

Fantom [35]

Answer:

Analytical Groups I and II

Explanation:

Precipitation reactions happen when anions and cations in aqueous solution mix together to form an insoluble ionic solid which is now referred to as a precipitate.

Whether or not a type of reaction like that takes place can be determined by utilizing the solubility principles for common ionic solids.

Write the equilibrium expression for N2 (g) + 3 H2 (g) ↔ 2 NH3 (g) + heat I have no idea where to even start, due to the corona

motikmotik

Answer:

The expression of an equilibrium constant will given as:

$K_c=\frac{[NH_3]^2}{[N_2][H_2]^3}$

Explanation:

Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios. It is expressed as $K_{eq}$

K is the constant of a certain reaction when it is in equilibrium

$N_2 (g) + 3 H_2 (g)\rightleftharpoons 2 NH_3 (g) + heat$

The expression of an equilibrium constant will given as:

$K_c=\frac{[NH_3]^2}{[N_2][H_2]^3}$
