Answer 1

Answer 2

I thinks its A or C

Answer 3

yup u are right its both A and C b coz,
A and C. Lead is more toward the bottom of the periodic table therefore it is heavier than all other elements. Also .5 molar is more that 25 atoms. The answer to the other question is process of elimination. At the atomic level there is no color nor light. Structure of atoms and molecules is determinded through reasoning of how they react.

Answer 4

so which one should I pick

Answer 9

Wording of the question is so funny:
"Which of the following has the greatest mass, IN GRAMS? (2 points)"

Would it be different with a mass in kilograms, in ounces, or in uznkchviuhgfq?
;-)

Answer 10

Yep, coz in uznkchviuhgfq, 100 uz is lighter than 1 uz. We use reciprocals in uznkchviuhgfq :)
