In order for a nonmetal to obey the octet rule, a. gains protons b. loses electrons c. gains electrons d. loses protons

C. gains electrons.

Explanation:

Octet rule states that "it is the tendency of the atom to have eight electrons in its outermost valence electron shell".Nonmetals obey octet rule by gaining electrons to its outermost valence electron shell.For example: Cl which has 17 electron and its electronic configuration is 2,8,7 and it gain electron to have 8 electrons in its outermost electron shell to form Cl⁻ with electronic configuration of 2,8,8.

answer: mole of the gas

answer: mole of the gasexplanation:

answer: mole of the gasexplanation: this is because 1 mole of a gas is 22.4dm³, which is use in ideal gas
