C. seaborgium: atomic number 106, mass 266, neutrons 160
Explanation:
An atom is made up three fundamental particles:
- Protons are the positively charged particles in an atom
- Electrons are the negatively charged particles
- Neutrons carry no charges.
The mass number is the sum of protons and neutrons in an atom because they contribute to the mass of an atom.
The atomic number is the number of protons in an atom. For a neutral atom, it is the same as the number of electrons.
Number of neutrons = mass number - atomic number
For seaborgium,
Number of neutrons = 266 - 106 = 160
This is the only correct option given.

Answer: Remove the watch and watchband immediately, and rinse his wrist for at least 15 minutes to be sure all hazardous material has been washed away. Let the TA inspect his wrist to see if it is okay.
Explanation:
The question is incomplete, the choices are:
a. Take him to the safety shower, and make sure he stands under it for at least 15 minutes to be sure all hazardous material has been washed away. b. Remove the watch and watchband immediately, and rinse his wrist for at least 15 minutes to be sure all hazardous material has been washed away. c. Let the TA inspect his wrist to see if it is okay.
d. Rinse the watch band before allowing him to put it back on.
An acid is traditionally considered to be any chemical compound that, when dissolved in water, produces a solution with greater hydronium cation activity than pure water, i.e., a pH less than 7. Both corrosive acids (and also corrosive bases) <u>are capable of destroying skin</u> by catalyzing the hydrolysis of fats, which are chemically esters. Also, when acids attack metals, hydrogen gas is often released.
This is why your lab partner should remove the watch and watchband immediately, and rinse his wrist for at least 15 minutes to be sure all hazardous material has been washed away. This ensures that the acid is can not damage the skin. And also the person should make sure that someone qualified checks it to see if it is okay.
Answer:
Electrons would easily move through the person if there was no rubber around the wire.
Explanation:
The black rubber material is an insulator and will not allow the conduction of heat or electrical current through it. Electrical currents are generated by the movement of electrons through materials.
<em>Hence, if there was no rubber covering around the power cord, the person that plugged-in the power cord would have experienced electric shock because electrons would easily move through him/her from the wire. </em>
