Mass and volume are two units used to measure objects. Mass- the amount of matter an object contains and volume- how much space it takes up
<u>The correct answers are </u>
- An atom of oxygen and the ion of oxygen both have 8 protons.
- As you add or remove neutrons from the nucleus, isotopes are formed.
Answer: Options A and D
<u>Explanation:</u>
An isotope of an element is formed by varying their number of neutrons and not on changing the number of electrons or protons. Similarly, an atom can be converted into an ion by adding or removing one or more electrons.
So the number of protons will not be changed for becoming an ion. Thus, the correct answers are that an atom of oxygen and ion of oxygen will be having 8 protons. Similarly, an isotope formation is possible on addition or removal of neutrons from the nucleus. All other options are not true as there will be no change in the number of electrons for isotope formation.
Write a balance equation for the reaction between the analyte and the titrant.
Calculate the # of moles of titrant using the volume of titrant required and the concentration of titrant.
Calculate the # of moles of analyte using the stoichiometric coefficients of the equation.
Calculate the concentration of the analyte using the number or moles of analyte and the volume of analyte titrated.

Answer:
The correct answer is - C) a different number of neutrons per atom.
Explanation:
Isotopes of an element are the same element and same atomic number but with different atomic mass and physical properties. The difference in their atomic mass occurs due to isotopes of an element have a different number of neutrons per atom.
The number of protons and the numbers of electrons are the same in the isotopes but only change occurs in the numbers of the neutrons. In isotopes of uranium U-233, U-235, and U-238 have the same number of protons but a different number of neutrons per atom.
