"m" is not a formula, it's a letter. The most common usage of it that I can think of is as the symbol for "mass", though in chemistry it's sometimes used to mean "molal".
Assuming the questioner means M+2 and X-3, the formula must be M3X2, so that the total charge will be zero.
it is a chemical formula. H2 means there are 2 hydrogen atoms, and O2 means there are 2 oxygen atoms. and yes it is a compound, Hydrogen Peroxide.
It is a formula, e, m and c can represent an infinite amount of numbers, and are meant to be substitued by the number, as you need to know at least 2 of them to figure out the entire formula.
It means that there are 2 carbon atoms, 6 hydrogen atoms and one oxygen atom present, because of the -OH group on the end of the formula you know that it is an alcohol and because it has two carbons it is named ethanol.

Significant figures. Basically, 0.5 m means "between 0.4 and 0.6 m" and 0.50 m means "between 0.49 and 0.51 m."
they both start with the letter m and in science that means they can breed.
There is no element symbolized as "M". If you find M in a chemical formula or equation, it most likely means any metal element (i.e., iron, silver, etc). There are three metals which begin with M: magnesium (Mg), manganese (Mn) and molybdenum (Mo).
The formula for D m v would be D=M/V. This is the formula for density.
a = F/m is Newton's 2nd Law. It means that an object's acceleration ' a ' is the samevalue as dividing the force applied to the object ... ' F ' ... by the object's mass ' m '.
This is Lithium Chlorate! be very careful with this substance! dont get it on ANY part of your body!
1,000,000 L = 1 ML, in science the prefix M means 10^6
P= M/No
Assuming the questioner means M+2 and X-3, the formula must be M3X2, so that the total charge will be zero.
m = k/ln
it is a chemical formula. H2 means there are 2 hydrogen atoms, and O2 means there are 2 oxygen atoms. and yes it is a compound, Hydrogen Peroxide.
A hypotheses in science means it is an educated guess.
