If you use rate laws then your answer will be more supported. Laws can not change, so if you use rate laws then the student will get a more accurate answer then if they don’t use rate laws.
The empirical and molecular formula : C₂₁H₂₂N₂O₂
<h3>Further explanation</h3>
Given
The percent composition of an unknown substance is 75.42% Carbon, 6.63 % Hydrogen,
8.38 % Nitrogen, and 9.57 % Oxygen
Required
The empirical and molecular formula
Solution
C : 75.42 : 12 = 6.285
H : 6.63 : 1 = 6.63
N : 8.38 : 14 = 0.599
O : 9.57 : 16 = 0.598
Divide by 0.598
C : H : N : O = 10.5 : 11 : 1 : 1 = 21 : 22 : 2 : 2
The empirical formula : C₂₁H₂₂N₂O₂
(C₂₁H₂₂N₂O₂)n = 334
(334)n=334
n = 1
Answer: capsaicin C18 H27 NO3
Explanation: I just know the last one sorry G
Answer:
0.40 L
Explanation:
Calculation of the moles of 
as:-
Mass = 51.24 g
Molar mass of = 171.34 g/mol
The formula for the calculation of moles is shown below:
Thus,
Volume = 1.20 L
The expression for the molarity is:
Thus,
Considering
Given that:
So,
<u>The volume of 0.24925M stock solution added = 0.40 L

Sodium want to give up an electron and "will always want to give up an electron* because less energy is needed to remove the one valence electron of sodium in order to have an octet configuration. This is the reason why sodium and other alkali metals form positive ions so easily.
<h2>Case study</h2>
For instance: In forming an ionic bond, the sodium atom, which is electropositive, loses its valence electron to chlorine. The resulting sodium ion has the same electron configuration as neon (1s2 2s22p6). It has a +1 charge, because there are 11 protons in the nucleus, but only 10 electrons around the nucleus of the ion
