mol C (MW=12 g/mol)
![\tt \dfrac{18.24}{12}=1.52](https://tex.z-dn.net/?f=%5Ctt%20%5Cdfrac%7B18.24%7D%7B12%7D%3D1.52)
mol H(MW=1 g/mol) :
![\tt \dfrac{0.51}{1}=0.51](https://tex.z-dn.net/?f=%5Ctt%20%5Cdfrac%7B0.51%7D%7B1%7D%3D0.51)
mol F(MW=19 g/mol)
![\tt \dfrac{16.91}{19}=0.89](https://tex.z-dn.net/?f=%5Ctt%20%5Cdfrac%7B16.91%7D%7B19%7D%3D0.89)
mol ratio of C : H : O =1.52 : 0.51 : 0.89=3 : 1 : 1.75=12 : 4 : 7
Empirical formula : C₁₂H₄F₇
(Empirical formula)n=molecular formula
( C₁₂H₄F₇)n=562 g/mol
(12.12+4.1+7.19)n=562
(281)n=562⇒ n =2
Molecular formula : C₂₄H₈F₁₄
Answer:
The same element that contain equal number if protons but different number of neurons in their nuclei and hence differ in relative atomic mass
Answer:
radio waves
Explanation:
On the far left of the diagram are radio waves, which include microwaves. They have the longest wavelengths and lowest frequencies of all electromagnetic waves. They also have the least amount of energy.
<span>The polar molecules possess the permanent dipole moments caused by slight charge separation in the molecule. In the case of non-polar molecules, the induced electric dipoles are created by an applied electric field causing the slight separation of positive and negative charges in the molecules. The induced electric dipoles are much weaker than permanent electric dipoles.</span>
