Answer:
the enthalpy of the bond between chlorine and ozone is the 122,8 kj
Explanation:
Review Hess's Law
Inverse equation (1): Cl (g) + 2O2 (g) ==> Cl) (g) + O3 (g) ∆H = +122.8 kJ / mol (note change in sign of ∆H)
Copy equation (2): 2O3 (g) ===> 3O2 (g) ∆H = -285.3 kJ / mol
Add the 2 equations: 2O3 (g) + Cl (g) + 2O2 (g) ===> Cl)) g) + O3 (g) + 3O2 (g) and cancel common species
When you do this, you end up with the desired equation

Answer:
The kinetic order in HI is x= 2
Explanation:
Generally the slow step in a reaction mechanism is the rate determining step
Now with this knowledge at the back of our minds we can see that the number of moles of HI i s 2 which implies that the order of HI is 2m
So we can represent the rate law as
hence
x = 2
Answer:
g. red, orange, yellow, blue
Explanation:
red is the hottest color and blue is the coolest. :)
The answer is "A". Hope this helps.
The atomic number of an atom (Z) is equal to the number of protons.
The mass number of an atom (A) is equal to the number of protons plus the number of neutrons (N), i.e. A = Z + N
Therefore, N = A - Z = 7 - 3 = 4.
So, this neutral lithium atom has 4 neutrons.
Answer: 4.
