Could you further explain what you are asking
Answer:
D. number of neutrons
Explanation:
Isotopes of the same element must have the same number of neutrons. Neutrons of an atom are the uncharged particles within the nucleus.
Isotopy is the existence of two or more atoms of the same element having the same atomic number but having different mass number due to the differences in the number of neutrons in their various nuclei.
Therefore, isotopes differs based on the number of neutrons they contain.
Solid Magnesium is considered as active metal so it reacts with strong acids like HCl and H₂SO₄ liberating Hydrogen gas according to the following equations:
Mg(s) + 2 HCl(aq) → MgCl₂(aq) + H₂(g)
Mg(s) + H₂SO₄(aq) → MgSO₄(aq) + H₂(g)
so the amount of solid magnesium decrease by addition of strong acid to it.
The conversion factor between yards to inches is 1 yard is equal to 36 inches. In converting 16.7 inches to yards, one must simply multiply it with the conversion factor.
16.7 inches *(1 yard/36 inches) = <span>
<span>0.463888889 yards
The answer is 0.46 yards.</span></span>
