In the equation "you = mgh", divide both sides of the equation by mg, or you/mg = mgh/mg. The answer then is h = you/mg.
An example of a wrong function equation is f(x) = sqrt(x) for all non-negative x.
Basically, if you check the dimensions of an equation and get different dimensions on the left and on the right, the equation is definitely wrong. If you get the same dimensions, it MAY be right.

A dimensional check in an equation can provide a quick check about the possible correctness of the equation. For example, if you are supposed to calculate a speed, the dimensions of the result MUST be of the form [distance] / [time] (or something that you can simplify to distance/time). If it doesn't, the formula is wrong. If it does, it MIGHT be correct.
The reaction is:2 Mg + O2 = 2 MgO
In the equation "you = mgh", divide both sides of the equation by mg, or you/mg = mgh/mg. The answer then is h = you/mg.
If you express your answer as a chemical equation with all forms given, you would get: Mg+(g) + e- -> Mg (g)
HCl + Mg -----> MgCl2 + H2
Mg+O2----->MgO
The word for which "mg" is an abbreviation is "milligram". The element for which Mg is the symbol is magnesium.
word equation : magnesium + water --> magnesium hydroxide + hydrogen chemical equation : Mg + 2H2O → Mg(OH)2 + H2
i am not sure but it seems that magnesium or mg + HCl = magnesium cloride MgCl. how would you account for the hydrogen ions? well you would have to balance the equation by 2Mg + 2HCl = 2MgCl + H2. so my answer would by hydocloric acid (HCl) No, that equation is WRONG! The correct equation is: Mg + 2HCl --> MgCl2 + H2. The H2 bubbles away as gas. The valency of Mg is 2+ and that of Cl is 1-.
Mg + 2HCl ------> MgCl2 + H2
mg+ 2e
MgO2
The equation is H2SO4 + Mg(OH)2 --> MgSO4 + 2H2O
