D. All of the above. Developing medicine, analyzing compounds and producing new product such as plastic all have to deal with chemistry.
Molarity = moles of solution/ liter of solution
4.32x10^2/20
432/20=
21.6 M
Answer:
B. An ionized atom has a number of protons that is unequal to the number of electrons.
Explanation:
For a neutral atom , the number of proton and electron is equal. An ionized atom has either loss or gain electron, thereby making the number of proton and electron unequal. The answer B is true because an ionized atom has either loss or gain electron to make the number of electron and proton unequal.
Option A is incorrect because a cations holds a positive charge when it loss one or more electron not when it gains one or more electron(s). Anions possess negative charge for gaining electron(s).
Option C is not true because ions can also carry negative charges and they are called anions.
Option D is false because losing one or more electron will turn an atom to a cations.
The blank is atoms. Structural formulas show the atomic arrangement in a molecule.
