I think the answer is, Thermal? I hope u get it right
Answer: There are 
atoms in 24 moles of Fe.
Explanation:
According to the mole concept, 1 mole of a substance contains 
atoms.
Therefore, atoms present in 24 moles of Fe are calculated as follows.
Thus, we can conclude that there are atoms in 24 moles of Fe.
Answer: 0.0106 mol of N in 0.233g of N2O
Explanation:
To solve this you find out how many mol of N2O you can multiply that by 2 to find the mol of N. There are 2 N for every one molecule of N2O.
To do this, you can use the Atomic Mass Unit of the atoms to find the mol. 1 mol of hydrogen has weights 1 gram, hydrogen has a atomic mass unit of 1. Atomic mass unit short hand is amu.
For molecules if you take the total of amu for each atom in the molecule and add them together you will have the weight of the molecule in amu.
The amu can be converted into how many grams are in one mole.
N is nitrogen which has an amu of 14.
O is oxygen which has an amu 16
2 * 14 + 16 = 44 amu
1 mol of N2O is 44 grams.
0.233g / 44 g / mol = .00530 mol of N2O
There is 2 N in each mol of N2O which means that .00530 mol * 2 = 0.0106 mol of N
There are 0.0106 mol of N in 0.233g of N2O

The method that can be used to separate the mixture is chromatography.
<h3>
What is chromatography?</h3>
"Chromatography" is obtained form a Greek word which literarily means, color writing. It is a method of separation which is common in separating a mixture of pigments.
To obtain the colors used, two solvents are mixed and the sample ink is dissolved in the solvents then spotted on a thin layer and put into a TLC chamber then the chromatogram is allowed to develop.
The various components of the pigment will appear on the chromatogram and can be identified using spectrophotometry. The Rf values of each component can also be used to identify it.'

Answer:
Look at the periodic table of elements
Explanation:
Group 1 is the most reactive and to the right
Group 18 is least reactive and all the way to the left. The rest are in between. The groups go vertical.
