Answer:
the HOMO-LUMO energy difference in ethylene is greater than that of cis,trans−1,3−cyclooctadiene
Explanation:
The λmax is the wavelength of maximum absorption. We could use it to calculate the HOMO-LUMO energy difference as follows:
For ethylene
E= hc/λ= 6.63×10^-34×3×10^8/170×10^-9= 1.17×10^-18J
For cis,trans−1,3−cyclooctadiene
E= hc/λ=6.63×10^-34×3×10^8/230×10^-9=8.6×10^-19J
Therefore, the HOMO-LUMO energy difference in ethylene is greater than that of cis,trans−1,3−cyclooctadiene
Answer:
Explanation:
According to Kinetic Molecular Theory, an increase in temperature will increase the average kinetic energy of the molecules. As the particles move faster, they will likely hit the edge of the container more often.
Answer:
2) HClO3 is stronger because chlorine is more electronegative than iodine.
Explanation:
The more electronegative the element is the more strong or acidic it becomes.
Chlorine being more electronegative than Iodine makes it easier for it to pull the electron of hydrogen more strongly and hence has a higher tendency to release a H+ unit. Hence that makes it stronger.
Answer:
the answer is 7 which is the atomic number of nitrogen
Explanation:
Al+Na=24
24/Oxygen (8) =3
3x rounded atomic mass of Ne (3x20) = 60
60+ 20 (# of neutrons in K)=80
80-30 (# of electrons in zinc)= 50
50/25 (the atomic number of Mn)=2
2x9 (number of protons in F)= 18
18+24 (atomic mass of Mg)=42
42/6 (number of neutrons in boron)=7
7 is the atomic number of Nitrogen (N)
The cycle is called carbon cycle :)
