There are two possibilities

First, they may want you to say that NaCl is bound in a crystal with the Na+’s attracting all the cl-s. Then water comes along and hydrates the ions enabling them to leave one another and enter the solution.

Second, you may be talking about a so called born haver diagram which considers melting and boiling NaCl so that you have a gas of Na+’s and Cl-‘s then you calculate the amount of energy you get when putting the gas ions in water.

λmax for the π → π* transition in ethylene is 170 nm. Is the HOMO-LUMO energy difference in ethylene greater than or less than t
-Dominant- [34]

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

What is the relationship between the motion of molecules and the kinetic energy of the particles?
Lorico [155]

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.

Between HClO3 and HIO3, which is stronger and why? Question 16 options: 1) HClO3 is stronger because chlorine is in a higher oxi
natima [27]

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.

I need help on this fast plz
algol [13]

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)
