Explanation:
Answer:DNA (or deoxyribonucleic acid) is the molecule that carries the genetic information in all cellular forms of life and some viruses. It belongs to a class of molecules called the nucleic acids, which are polynucleotides - that is, long chains of nucleotides.hope it helps
Explanation:
9,353 - 1,095 - 5,217 = mN
3,041 = mN
H:C:N= 1,095/1 : 5,217/12 : 3,041/14
H:C:N = 1,095 : 0,43475 : 0,2172
H:C:N = 5,037 : 1,99985 : 0,99912 ≈ 5 : 2 : 1
H₅C₂N (C₂H₅N)
Mg(s)+2HCl(aq)→MgCl2(aq)+H2(g)
(since the molar mass of Mg is not given, assuming that it's mola mass is 24gmol¯1)
1st find the moles of Mg using the equation n=m/M where
n - moles
m - mass
M - molar mass
Therefore :
![n \: = 9.45 \:g\div 24g {mol}^{ - 1}](https://tex.z-dn.net/?f=n%20%5C%3A%20%20%3D%209.45%20%5C%3Ag%5Cdiv%2024g%20%7Bmol%7D%5E%7B%20-%201%7D%20)
n = 0.39375mol
n = 0.39mol
Then using the equation n=V/Vm where;
n = mol
V = volume
Vm = molar volume
Find the volume.
n = V/Vm
(n =0.39mol , Vm = 22.4dm³mol¯¹)
V = 0.39mol×22.4dm³mol¯¹
V = 8.736dm³
