Decreasing is the opposite of increasing. When you increase something, you have more of it; when you decrease something, you have less of it. For example: we want to increase the number of students who graduate from college. We want to decrease the number of students who drop out.

Yes, that's the way spirits such as whiskey and brandy are made, by evaporating lower strength mixtures and condensing out the alcohol

If you actually burn it, you don't get any element. Water is driven off and the remainder oxidizes into carbon dioxide. You're probably asking about charring it, which is slightly different. In charring, the sugar never actually catches on fire, it just turns brown and then black. In this case, the element produced is carbon.

Because Chloropropane is an alkane but tert-butyl alcohol is an alcohol. The O-H bond is much more difficult to break than the C-H bonds in the hydrocarbons that make up chloropropane. O-H bonds need more energy to break them; therefore the tert-butyl alcohol has a higher boiling point than chloropropane.

The melting point of magnetite(Fe3O4) is 1538 Celsius, but does anyone know the boiling point?

The mole

a molecular solid...

Probably after 1910, for luminescent paints.

Today radium has only limited applications in research laboratories, for example for the preparation of radon standard solutions, in neutron sources of the type Ra-Be, etc.

Possible use in radiotherapy of some cancers.

Radium was used in the past for luminescent painting of watches and other instruments, was used in toothpaste, cosmetics, etc. These applications are not permitted now because radium is strongly radioactive and dangerous.

their not your just fat and adopted

the solvent the solute is the substance being dissolved and the solvent is the substance (liquid) the solute dissolves in ie: adding sweet 'n' low to iced tea, the solute is the sweet 'n' low and the solvent is the iced tea

Since blood is already liquid the particles would just mix together. Technically that would be dissolving.

Alkynes always form a triple bond. This being so, essentially, all you have are the two carbon molecules and the triple bond! No matter what way your turn it, or how you look at it, even if in a mirror (ie. optical isomerism) you will always have the same looking molecule while to have a geometrical isomer cis or trans form should be there.

gen equation for a compound to be a geometrica isomer:

1.YXC = CXY

2.YXC = CXZ
