Interpretation:
The benefits of radioactive sources of energy and the precautions for using them are to be mentioned.
Concept introduction:
The elements or compounds that emit radioactive energy can be used for various purposes.

Answer to Problem 106A
The uses of radioactive sources are:
- As radiotracers in chemical and biological reactions
- In nuclear power plants as fuel
- Sterilization of food products and medical instruments
The safeguards for using radioactive sources are:
- Wearing a personal protective equipment kit while handling the source
- Seating up a radioactive materials workplace
- Handling of materials in buildings with thick concrete walls
- Do not handle materials with excessive radiation without special containers
Explanation of Solution
Radioactivity is necessary in the above uses as:
- Radiotracers are traced by their radiation
- The radiation produced from the sources can be used to initiate chain fission reactions
- Radioactive radiations easily kill germs and bacteria
The radiations emitted by these sources are very harmful to humans which is why the above-mentioned precautions are necessary while handling radioactive materials.

Fuming H2SO4arrow_forwardConsider the following two acid-base reactions: OH OHI Based on what you know about the compounds and their acidity, which direction would you expect both of these reactions to proceed? Show your reasoning. A pKa table has been provided in case you need it.

Cl Cl (1) (2) (3) They find one will react quickly, one slowly, and one will not react at all. Which is which, and why? HINT: What is the reaction they're trying to do? Does that mechanism tell you anything about why something would be favored?arrow_forwardNH3 decomposes through an equilibrium reaction between NH3, H2, and N2. Only one of the options is correct:(A). The mechanism of the NH3 decomposition reaction must necessarily involve the collision of two NH3 molecules to induce a rearrangement of the atoms in this molecule.(B). The molecular weight of the NH3 decomposition reaction is 2 since two NH3 molecules must collide.(C). The rate of the NH3 decomposition reaction must be greater than that of NH3 synthesis, since the former requires two molecules to collide and the latter, four.(D). The NH3 decomposition reaction cannot occur in a single step.arrow_forward
- Given the equilibrium A2 + B2 ⇌ 2 AB where k1 is the rate coefficient of the forward reaction and k-1 is the rate coefficient of the reverse reaction, with the forward reaction being first-order in A2 and B2, and the reverse reaction being second-order in AB. Equilibrium will be reached later if the relative values of the constants are:(A) k1 high and k-1 high(B) k1 high and k-1 low(C) k1 low and k-1 high(D) k1 low and k-1 lowarrow_forwardA 2-step reaction has the following mechanism: | 1.
