C is the answer it’s not d because mackerel does not eat tuna I’m not sure tho
The standard enthalpy of formation for chlorine is zero but the standard entropy is larger than 0 because it is the elemental state of chlorine.
The standard enthalpy of formation for chlorine is zero because cl2 is the elemental state of chlorine and it does not require any energy for the formation of the standard state of chlorine.
The entropy of any system cannot be negative. It can only be positive or zero.
The entropy of a system will become zero only at a absolute zero temperature.
That's why the entropy of chlorine in elemental state is more than zero because absolutely zero temperature can't be obtained.

Answer: The mass number of an oxygen isotope that has nine neutrons is 17 and isotope is called as Oxygen-17.
Explanation:
Atomic number is defined as the number of protons or number of electrons that are present in an atom.
For a neutral atom:
Atomic number = Number of electrons = Number of proton
Atomic number= Number of protons = 8
Mass number is defined as the sum of number of protons and neutrons that are present in an atom.
Mass number = Number of protons + Number of neutrons
Given: Number of neutrons = 9
Thus mass number = Number of protons + Number of neutrons = 8 + 9 = 17.
Isotopes are elements which have same atomic number but different mass number.
Thus the mass number of an oxygen isotope that has nine neutrons is 17 and isotope is called as Oxygen-17.
Answer:
d orbital
Explanation:
Given that:-
The principal quantum number, n = 3
The acceptable values of azimuthal quantum number, l are:-
l = 0 , 1 , 2
l = 0 corresponds to s orbital which can accomodate 2 electrons.
l = 1 corresponds to p orbital which can accomodate 6 electrons.
l = 2 corresponds to d orbital which can accomodate 10 electrons.
<u>Thus, the highest energy orbital is: - d orbital</u>
Answer:
100 and 1 atm
