Chapter 2: Q24.75P (page 40)

AH nucleus decays with an energy ofMeV. Convert this energy into (a) electron volts; (b) joules.

Short Answer

Expert verified

a)1.861×104eVb)2.981×10-15J

Step by step solution

01

Step 1:To convert (a) electron volts (b) joules.

(a)

We have to convert 0.01861MeVinto electron volts.

1MeV=106eV

0.01861MeV=0.01861MeV×106eV1MeV=1.861×104eV

(b)

We have to convert 0.01861MeVinto joules.

1MeV=1.602×10- 13J

0.01861MeV=0.01861MeV×1.602×10- 13J1MeV=2.981×10- 15J

The radii of the lithium and magnesium ions are 76 pm and 72 pm, respectively. Which compound has stronger ionic attractions, lithium oxide or magnesium oxide?

State the mass law(s) demonstrated by the following experimental results, and explain your reasoning:

Experiment 1: A student heats 1.27 g of copper and 3.50 g of iodine to produce 3.81 g of a white compound; 0.96 g of iodine remains.

Experiment 2: A second student heats 2.55 g of copper and 3.50 g of iodine to form 5.25 g of a white compound, and 0.80 g of copper remains.

Magnesium oxide (MgO) forms when the metal burns in the air.How many grams of Mg are in534 g of MgO?

Choose the correct answer. The difference between the mass number of an isotope and its atomic number is (a)directly related to the identity of the element; (b) the number of electrons; (c) the number of neutrons; (d) the number of isotopes.

An ionic compound forms when calcium (Z = 20) reacts with iodide (Z = 53). If a sample of the compound contains 7.4×1021calcium ions, how many iodide ions does it contain?
