We can't use the nitrogen present in the atmosphere although 80% of the atmosphere consists of nitrogen only.We get this from the plants called as leguminous plants which can convert or fix atmospheric nitrogen into usable ones..
Answer:3844 cm^2
Explanation:
62 squared since it is a square, and area is base times height
CH3 is the empirical formula for the compound.
A sample of a compound is determined to have 1.17g of Carbon and 0.287 g of hydrogen.
The number of atom or moles in the compound is
1.17 g C X 1 mol of C / 12.011 g C = 0.097411 mol of C.
0.287 g H x 1 mol of H / 1 g H = 0.28474 mol H.
This compound contains 0.097411 mol of carbon and 0.28474 mol of Hydrogen.
So we can represent the compound with the formula C0.974H0.284.
Subscripts in formulas can be made into whole numbers by multiplying the smaller subscript by the larger subscript.
we can divide 0.284 by 0.0974.
0.284 / 0.0974 = 3.
So here, Carbon is one and hydrogen is 3.
We can write the above formula as a CH3.
Hence the empirical formula for the sample compound is CH3.

Answer: Families of ions that contain NITROGEN, SULFUR, and CARBON follow a pattern similar to that of the polyatomic chlorine ions.
Explanation: Plato
0.035L
35.4mL
Explanation:
Given parameters:
Concentration of HCl = 12M
Number of moles = 0.425mol
Unknown:
volume of solution = ?
convert from L to mL = ?
Solution:
Molarity is the amount of solute in a volume of solvent
Molarity = 
since the volume is the unknown, we make the subject of formula;
Volume = 
Volume = 
= 0.035L
Converting to mL gives:
1L = 1000mL
0.035L = (0.035 x 1000)mL , 35.4mL
