Write balanced equations for each of the following nuclear reactions: (a) 23892U + 10n → g + 23992U. (b) 168O + 11p → a + 179N. (c) 188O + 10n → b- + 199F.
Verified step by step guidance1
Step 1: Identify the type of nuclear reaction for each equation. For example, determine if it's a neutron capture, alpha decay, beta decay, or another type.
Step 2: For each reaction, apply the law of conservation of mass and atomic numbers. This means the sum of mass numbers (top numbers) and atomic numbers (bottom numbers) on the left side must equal the sum on the right side.
Step 3: For reaction (a), identify the missing particle 'g'. Use the conservation laws to find the mass number and atomic number of 'g'.
Step 4: For reaction (b), identify the missing particle 'a'. Again, use the conservation laws to determine the mass number and atomic number of 'a'.
Step 5: For reaction (c), identify the missing particle 'b'. Use the conservation laws to find the mass number and atomic number of 'b', considering that a beta particle (b^-) is an electron with a mass number of 0 and an atomic number of -1.

Open Question
It has been suggested that strontium-90 (generated by nuclear testing) deposited in the hot desert will undergo radioactive decay more rapidly because it will be exposed to much higher average temperatures. (a) Is this a reasonable suggestion? (Section 14.5) (b) Does the process of radioactive decay have an activation energy, like the Arrhenius behavior of many chemical reactions (Section 14.5)?
Textbook Question
Some watch dials are coated with a phosphor, like ZnS, and a polymer in which some of the 1H atoms have been replaced by 3H atoms, tritium. The phosphor emits light when struck by the beta particle from the tritium decay, causing the dials to glow in the dark. The half-life of tritium is 12.3 yr. If the light given off is assumed to be directly proportional to the amount of tritium, by how much will a dial be dimmed in a watch that is 50 yr old?
