The hypothesis can’t be a opinion or something that has nothing to do with your work
For example;if you want to see if your toilet paper is sturdy and you say “i think it will cause the commercial says it does” (wrong) answer would have to be “i infer that the toilet paper will be sturdy because it looks more resistant than other paper I’ve seen”
Answer: D.) 25.9%
Explanation:
Dinitrogen pentoxide chemical formular : N2O5
Calculating the molar mass of N2O5
Atomic mass of nitrogen(N) = 14
Atomic mass of oxygen(O) = 16
Therefore molar mass :
N2O5 = (2 × 14) + (5 × 16) = 28 + 80 = 108g/mol
Percentage amount of elements in N205:
NITROGEN (N) :
(Mass of nitrogen / molar mass of N2O5) × 100%
MASS OF NITROGEN = (N2) = 2 × 14 = 28
PERCENT OF NITROGEN : (28/108) × 100%
0.259259 × 100%
= 25.925%
= 25.9%
This is a chemical reaction because a precipitate (solid) was formed from 2 liquids, and there was a color change as well
