Chapter 1: Problem 15

Examining data obtained from mass spectrometry supports which of the following? (A) The common oxidation states of elements (B) Atomic size trends within the periodic table (C) Ionization energy trends within the periodic table (D) The existence of isotopes

Short Answer

Expert verified
The correct answer is (D) The existence of isotopes. Mass spectrometry gives information about the mass of particles, hence supporting the existence of isotopes which are atoms of the same element but with different numbers of neutrons (varying masses).

Step by step solution

01

Understanding the Options

Let's examine each option individually. (A) The common oxidation states of elements - mass spectrometry does not give direct information about the oxidation state of an element. (B) Atomic size trends within the periodic table - this technique does not provide information about the size of atoms. (C) Ionization energy trends within the periodic table - ionization energy defines the energy required to remove an electron from an atom or ion. Mass spectrometry does not give direct information about this. (D) The existence of isotopes - isotopes are atoms of the same element that have different numbers of neutrons, hence differing in mass. Considering what mass spectrometry does, determining the mass of particles, it is plausible that it gives information about isotopes of elements.
02

Choosing the Correct Option

From the analysis above, it is clear that mass spectrometry gives information about the mass of particles. This is consistent with Option (D) - The existence of isotopes, as isotopes of the same element have different masses. Therefore, the correct option that is supported by data obtained from mass spectrometry is (D) The existence of isotopes.

Most popular questions from this chapter

Which substance would have the highest boiling point? (A) Ethanol, because it is the most asymmetrical (B) Acetone, because of the double bond (C) Ethylene glycol, because it has the most hydrogen bonding (D) All three substances would have very similar boiling points because their molar masses are similar.

Use the following information to answer questions 29-31. Pennies are made primarily of zinc, which is coated with a thin layer of copper through electroplating, using a setup like the one above. The solution in the beaker is a strong acid (which produces H' ions), and the cell is wired so that the copper electrode is the anode and zinc penny is the cathode. Use the following reduction potentials to answer questions \(29-31 .\) $$\begin{array}{|l|l|}\hline \text { Half-Reaction } & {\text { Standard Reduction Potential }} \\ \hline \mathrm{Cu}^{2++2 e^{-} \rightarrow \mathrm{Cu}(s)} & {+0.34 \mathrm{V}} \\ \hline 2 \mathrm{H}^{++2 e^{-} \rightarrow \mathrm{H}_{2}(g)} & {0.00 \mathrm{V}} \\ \hline \mathrm{Ni}^{2++2 e^{-} \rightarrow \mathrm{Ni}(s)} & {-0.25 \mathrm{V}} \\\ \hline \mathrm{Zn}^{2++2 e^{-} \rightarrow \mathrm{Zn}(s)} & {-0.76 \mathrm{V}} \\ \hline\end{array}$$ What is the required voltage to make this cell function? (A) 0.34 V (B) 0.42 V (C) 0.76 V (D) 1.10 V

\(\mathrm{CaCO}_{3}(s)+2 \mathrm{H}^{+}(a q) \rightarrow \mathrm{Ca}^{2+}(a q)+\mathrm{H}_{2} \mathrm{O}(l)+\mathrm{CO}_{2}(g)\) If the reaction above took place at standard temperature and pressure and 150 grams of \(\mathrm{CaCO}_{3}(\mathrm{s})\) were consumed, what was the volume of \(\mathrm{CO}_{2}(g)\) produced at STP? (A) 11 L (B) 22 L (C) 34 L (D) 45 L

$$\mathrm{N}_{2}(g)+\mathrm{O}_{2}(g)+\mathrm{Cl}_{2}(g) \mapsto 2 \mathrm{NOCl}(g) \Delta G^{\circ}=132.6 \mathrm{kJ} / \mathrm{mol}$$ For the equilibrium above, what would happen to the value of \(\Delta G^{\circ}\) if the concentration of \(\mathrm{N}_{2}\) were to increase and why? (A) It would increase because the reaction would become more themodynamically favored. (B) It would increase because the reaction would shift right and create more products. (C) It would decrease because there are more reactants present. (D) It would stay the same because the value of \(K_{e q}\) would not change.

A 0.1-molar solution of which of the following acids will be the best conductor of electricity? (A) \(\mathrm{H}_{2} \mathrm{CO}_{3}\) (B) \(\mathrm{H}_{2} \mathrm{S}\) (C) \(\mathrm{HF}\) (D) \(\mathrm{HNO}_{3}\)
