Multiply the magnification or power of the objective lens times the power of the eyepiece and it equals the total magnification
The rule of zero charge states that in an ionic compound, the total positive charge from cations must equal the total negative charge from anions for the compound to be neutral. This rule allows you to determine the ratio of cations to anions in the compound, aiding in predicting the formula of the ion compound.
Oculars are generally 10x, so I assume you're talking of the 40x objective (10x40=400, how total magnification is derived). The most important rule is NEVER touch the coarse focus adjustment, only the fine; you run the risk of breaking the specimen or the objective if you mash the two together. Other things to consider- high light level, make sure koehler illumination is established and adjust your field aperture to eliminate refringence.
If a compound contains an even number of nitrogen atoms (or no nitrogen atoms), its molecular ion will appear at an even mass number. If, however, a compound contains an odd number of nitrogen atoms, then its molecular ion will appear at an odd mass value. This rule is very useful for determining the nitrogen content of an unknown compound.
This is an assymetric alkene.
Because as a rule only a chemical compound has a chemical formula; a mixture contain two or many componds and each compound has a different chemical formula.

The sum of oxidation numbers in a compound is zero for a neutral compound and equal to the charge of the ion for an ionic compound. This rule stems from the fact that the total charge of a compound must be zero for a neutral compound and must balance out for an ionic compound.
One rule is while looking through the scope move the microscope UP only. If you don't then you risk bumping into your sample or slide.Use the large or gross focuser first then your small or microfocuser.

As a very general rule, the higher the magnification the better.
A rough rule-of-thumb magnification level is ten times normal vision, written as 10x. This is the general magnification standard for jewelery. Some diamond merchants, however, may use a stronger magnification by personal choice.

When discovering a new compound, you are presenting it as a scientific finding rather than a rule. It becomes part of the body of knowledge in science and must be rigorously tested and verified by other researchers before it can be considered a rule or theory.
The rule of zero helps you predict the formula of an ionic compound because the anion will always want to bond with a action to get zero net charge on the compound.
Yes. As a basic rule of thumb, a compound that is comprised of a metal and non-metal is an ionic compound.
