Answer:
If the tilt of the Earth's axis is changed there would be a change in the season because the season is caused by the Earth's tilt (23.5 degrees) and the revolution or orbit.
Explanation: c= 1.2 mol/l (concentration ) and V = volume.
Amount of substance n= cV. Also n = mass/ molar mass m/M.
You need further information to solve the problem.
Either mass or amount of substance of HNO3 Is missing
Answer:
Explanation:
Hello,
In this case, since the dissociation of aluminum hydroxide is:
The equilibrium expression is:
Thus, given the concentration of hydroxyl ions in the solution, and the 3:1 mole ratio with the aluminum ions, the concentration of those turn out:
Therefore, the solubility product, Ksp turns out:
