The mass number of an atom is the sum of its protons and neutrons. the most common isotope of argon is ar-40 (40 ar), with a natural abundance of 99.6 %. the mass number for ar-40 is 40 . It is having 18 protons and 22 neutrons. So its mass number is 40 that is equal to sum of total number of protons and neutrons.
Mass number=total number of protons and neutrons
=18+22
=40
The answer is Nicotine.
Hope that helps!
Answer:
B
Explanation:
I believe it is compound B, because ionic compounds can form crystals, and they can conduct electricity when dissolved in water.

Sulfur is characterized as a non-metal because it is consistent with the 3 physical properties listed for nonmetals. It is a poor conductor of heat and electricity because the electrons are not free to move. An element that becomes an ion must have free room for its electrons to move and to create an electrical charge.
Answer:
97.44 K
Explanation:
to answer this one you should use the ideal gas law PV=nRT where P=pressure, V=volume, n=number of moles of gas, R=universal gas constant (0.0821), and T=temperature in Kelvin. All you have to do is substitute the givens into the equation.
(3.10)(16)=(6.20)(0.0821)(T)
then simplify
49.6=(.50902)(T)
divide to get T alone and you get about 97.44 K as your answer
