<span>First:
46.7 g of N with 53.3 g of O,
=> mass ratio O to N = 53.3 / 46.7 = 1.1413
Second
17.9 g of N and 82.0 g of O.
mass ratio of O to N = 82.0 / 17.9 = 4.5810
Third
Ratio of the mass ratio of O to N in the second compound
to the mass ratio of O to N in the first compound =
= 4.5810 / 1.1413 = 4.013 ≈ 4

The answers are true, true, false, true, and false.
C is the answer because he wants to know if less force is needed to pull on a slippery surface which reduces friction
Answer: In equation of reaction nitrogen N2 is formed instead of O2
Formula of nitroglycerin is C3H5(NO3)3
Number for N2 is 12. Thus one mole nitroglycerin produces 3 moles N2
