Multiply the magnification or power of the objective lens times the power of the eyepiece and it equals the total magnification

Proper use of microscope in 400 magnification?
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.
Which compound obeys Markovnikov rule on reaction with HCl?
This is an assymetric alkene.
Is cyclohexanone an aromatic compound?
No, cyclohexanol is not an aromatic compound since it does not exhibit aromatic resonance stabilization (like benzene). Refer to Hückel's rule for clarification of the definition of an aromatic compound.
How does the rule of zero charge help you predict the formula of an ion compound?
The rule of zero charge helps you predict the formula of an ionic compound because you know that what anion is present, the action that bonds will make the net charge zero.
What is nitrogen rule?
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.

What kind of scopes do you use for varmint hunting?
As a very general rule, the higher the magnification the better.
Which lenses are used by diamond merchants?
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.
Is ZnH2 an ionic compound?
Yes. As a basic rule of thumb, a compound that is comprised of a metal and non-metal is an ionic compound.
What is the 18 electron rule?
The 18 electron rule (also known as the Effective Atomic Number Rule or EAN rule) was originally proposed by N.V. Sigwick when extending the octet rule proposed by G.N. Lewis in applying it to organometallic compounds. The idea behind both of these rules is that in a compound the sum total of all of the electrons would have the configuration of a noble gas. With the octet rule there is the basic assumption that the central atom in the compound is 8 (the maximum capacity of the s and p orbitals). The 18 electron rule is based on a similar idea as the octet rule, however it takes into consideration the d orbital too - 2 (s) + 6 (p) + 10 (d) = 18.
What things were invented between 1450 to 1750?
1519- Ball Bearing by Leonardo da Vinci 1551- Steam Turbine by Taqi al- Din 1590- Compound Microscope by Dutch Lens 1608- Telescope by Hans Lippershey 1620- Slide Rule- by William Outghtred
What compound is the octet rule expanded to include 12 electrons?
SF6
Which compound obeys Markovnikov rule on reaction with HCl?
This is an assymetric alkene.
What is optical bench model of microscope?
the principle of the microscope will be better understood by setting up such an instrument on the steel rule optical bench and using thin spectacle lenses in place of the more complicated objectives.
How does the rule of zero charge help ypu predict the formula of an ionic?
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.
What is the total number of bonds normally associated with a single carbon atom in a compound?
4. Carbon obeys the octet rule. In covalent conpounds it has 4 covalent bonds. It can also form ionic compounds (carbides).
How does the rule zero charge help you predict the formula of an ionic compound?
The rule of zero charge helps you predict the formula of an ionic compound because you know that what anion is present, the action that bonds will make the net charge zero.
