Because the kind of compounfds that you try to determine using paper chromatography (organic compounds) are usually not soluble in water. Furthermore, water could react chemically with some of this compounds, because it's a very reactive molecule. You need organic solvents that are mostly inert.

Changing from liquid to gas is a chemical change.<br> True<br> False
Korolek [52]

Answer:

This is False

Explanation:

A chemical change is when the matter is completely changed.

When you have water and boil it to be a gas, it is still the same matter, just in a different form.

I hope this helps :)

When you count up the electrons in a Lewis Structure, do double and triple bonds count as 4 or 6 electrons?
natima [27]

Answer:

Double=4 and triple=6

Explanation:

This is because double bonds are two pairs of electrons are shared between atoms and triple bonds are three pairs, and one pair of electrons is 2, so 2 x 2=4 and 2 x 3=6.

Which of the following statements is true?
Anna007 [38]

Answer:

C. Lithium is most easily oxidized of the metals listed on the activity series and therefore it will most easily give electrons to metal cations

Explanation:

"Lithium" is a type of alkali metal that has a "single valence electron." Since it is a reactive element, it easily gives up an electron when it is combined with other elements. Such giving up of electron is meant to create compounds or bonds.

Among the common metals listed, "lithium" is the most easily oxidized. This means that it donates its electrons immediately. Such combination makes it exist as a<em> "cation"</em> or <em>"positively-charged."</em>

So, this explains the answer.

If you have A 6-g sugar cube (C12H22011) and dissolved in a cup of hot tea. The
Iteru [2.4K]

The percentage of sugar in the solution is 1%

To solve this question, we need to find the percentage of 6 out of 600.

Data given;

  • mass of sugar = 6g
  • mass of solution = 600g
<h3 /><h3>What is Percentage</h3>

This is the rate or proportion of a substance in the total value and multiplied by 100.

The percentage of sugar in the solution is calculated by

\frac{6}{600} * 100 = 1 %

The percentage of sugar in the solution is 1%
