Answer:
Explanation:
The reaction we need to calculate:
1) 
We need the ClO in the products side, so we use the inverse of this reaction:
2) 
Now we need to combine this two:
The enthalpy of reaction:
Answer: 100kPa
Explanation:
P1 = 3.00 x 10² kPa , P2 =?
T1 = 30°C = 30 +273 = 303k
T2 = —172°C = —172 + 273 = 101k
P1/T1 = P2/T2
3 x 10² / 303 = P2 / 101
P2 = (3 x 10² / 303) x 101
P2 = 100kPa
I don't know your mc choices so I am going to go with "the number of valence electrons"
Oxidation number: the amount of electrons an atom gains, loses or shares when it forms chemical bonds. As for the valence electrons, those are the electrons that are responsible for bonds/ reactions.
Answer:
Orbitals
Explanation:
An orbital is a region in space where there is a high probability of finding an electron. An orbital is a probability function put forward by the wave mechanical model of the atom.
The wave mechanical model derives its principles from the Heisenberg uncertainty principle and the principle of wave particle duality.
Since we can not describe the momentum or position of the electron at any time with certainty, an orbital is a probability function that describes the region in space where the electron may be found around the nucleus.
