De Broglie's equation is basically used to describe the wave-like properties of matter. It suggests that particles with extremely small masses like electrons exhibit properties of waves that can be detected.

I would say when you are working on intermediate calculations, then have more numbers and at the end round to correct number because if you round to close in the intermediate calculations that can affect your final answer by a lot.

Sometimes if I am working with molar mass and Molarity I just write down the units rather than M

My answers also have been of because depending on which periodic table you use the masses are a little different and also how you round and when you round affects your answer as well.

114=114.
They both mean the same thing and they both have 3 sig figs

The problem refers to a heptahydrate and you have to account for its mass and moles when doing problems regarding it.

Most often Ionic bonds are stronger than covalent bonds; however, there are some covalent bonds stronger than ionic. Ionic bonds are formed as a result of a mutual attraction between ions that have opposite charges. Covalent bonds are formed as a result of the sharing of electrons. Ionic bonds are s...

Any acid that ends in -ic means it is made up of a nitrate ion. AN easy way to remember it would be I ATE something ICky.
Thus Nitric Acid=HNO3
