Answer to Problem 20.101QP
The balanced equation for decay of Bromine-82 is,
The balanced equation for decomposition of
Explanation of Solution
When Bromine-82 undergoes beta (
Already given that Hydrogen bromide made with Bromine-82 isotope. Above equation shows that
(b)
Interpretation:
Bromine-82 decays by emission of beta particle. The half-life of Bromine-82 is 1.471d.
The quantity of
(b)
Answer to Problem 20.101QP
The quantity of
At
Explanation of Solution
Use the rate law to identify the fraction after 10.0h. The half-life is 1.471d.
Taking antilog on both sides gives,
So, the number of moles of
The reaction can be summarized as follows,
To determine the pressure in the flask, we required the total moles of gas. This is,
Therefore, the pressure in the flask is,

- Write a balanced equation for each of the following nuclear reactions: (a) bismuth-212 decays into polonium-212. (b) beryllium-8 and a positron are produced by the decay of an unstable nucleus. (c) neptunium-239 forms from the reaction of uranium-238 with a neutron and then spontaneously converts into plutonium-239. (d) strontium-90 decays into yttrium-90arrow_forwardA radioactive metal atom decays (goes to another kind of atom) by emitting an alpha particle (He2+ ion). The alpha particles are collected as helium gas. A sample of helium with a volume of 9.050 mL was obtained at 765 mmHg and 23C. How many atoms decayed during the period of the experiment?arrow_forward
