A rightward change in equilibrium.
The concentration of gases = [H2] will decrease, [N2] will increase, [NH3] will increase when the new equilibrium is reached.
Additional heat is produced.
The forward and backward reactions' rates quicken in the new equilibrium.
The equilibrium constant decreases as more heat is released.
the exothermic nature of the process.
The equilibrium constant would not have changed if the temperature had remained constant.

Explanation:
The property of a substance to resist the flow of motion is known as viscosity. And, more is the density of a substance more will be its viscosity.
Whereas, lesser is the density of a substance then it is easy for the substance to move.
This means that more is the viscosity of a substance least will be its flow and when a substance has lesser viscosity then it will readily flow from one point to another.
Thus, we can conclude that the viscosities of several liquids are being compared. All the liquids are poured down a slope with equal path lengths. The liquid with the highest viscosity will reach the bottom last.
The salt whose aqueous solubility will most likely to change the pH of the solution is CaF2(aq).
The pH of a salt solution depends on the nature of the acid and base that forms the salt.
- Salt of a weak acid and a strong base yields a basic solution
- Salt of a strong acid and a weak base yields an acidic solution
- Salt of a strong acid and a strong base yields a neutral solution.
Since HF is a weak acid, its salt CaF2 will be slightly basic when dissolved in water hence the pH of the solution is altered.

Answer:
2.67g Ni
Explanation:
To convert from moles to mass, use molar mass as a conversion factor.
Nickel has a molar mass of 58.69g/mol.
0.0455mol (
) = 2.67g Ni
Answer:
B
Explanation:
Iodine has a negative charge, so it will gain electrons.
