Isotopes of the same element differ only in the number of neutrons an atom has. Its still the same element because the number of protons define an element. Just their neutrons and mass number is different.
Question 5 is the second one.
Answer:
D has to be based on facts so d would be the answer and idea that can only be proven true those are facts not hypothesis or guesses
Explanation:
based on a body of facts that have been repeatedly confirmed through observation and experiment. Such fact-supported theories are not "guesses" but reliable accounts of the real world."
The bond between the N and 0 (double bond) transfers and gives a -ve charge on O and a +ve charge on N atom at the group . Thus the +vely charged nitrogen is electron-deficient pulling electrons towards itself!
The combination of the +vely charged nitrogen and the electronegative oxygen atom leads to delocalization causing the resonance effect.
Answer:
the temperature changes finally to 339k because of the increase in pressure of the gas
