Frequency.
The equation to find the velocity of a wave length is:
v=fλ
V stands for velocity
F stands for frequency
λ stands for wavelength
The amount of kinetic energy that an object has depends on its mass or how heavy it is and how fast it is moving, or velocity
Not strong base and acid, not dissolved or not aqueous.
Equation: MgOH2 (s) --> MgO (s) + H2O (g)
And it's already balanced.
I had chemistry this semester too.
