I guess examples of solid and gas???? You have to be more descriptive.....
I believe the answer is 1,2, and answer 5 is correct.Hope this helps
An energy level of a certain atom is further divided into the orbitals. There are four (4) orbitals. These are the s orbitals, p orbitals, d orbitals, and f orbitals. They are already arranged above as to how they are to be filled. The number of electrons that each can hold are as follows:
s orbitals = 2 electrons
p orbitals = 6 electrons
d orbitals = 10 electrons
f orbitals = 14 electrons
Answer:
375.3KJ
Explanation:
The following data were obtained from the question:
Mass of water = 166g
Heat of Vaporisation (ΔHv) = 40.7kJ/mol
Heat (Q) =..?
Next, we shall determine the number of mole in 166g of water. This is illustrated below:
Mass of H2O = 166g
Molar mass of H2O = (2x1) + 16 = 18g/mol
Number of mole = Mass/Molar Mass
Number of mole of H2O = 166/18
Number of mole of H2O = 9.22 moles.
Now, we can obtain the heat required to vaporise the water as shown below:
Q = n·ΔHv
Q = 9.22 mol x 40.7kJ/mol
Q = 375.3KJ
Therefore, the heat required to vaporise the water is 375.3KJ.
