Answer:
see calculations in explanation
Explanation:
percent = part/total x 100%
part = ∑ atomic mass of element
- hydrogen = 1.008 amu (atomic mass units)
- carbon = 12.011 amu
- nitrogen = 14.007 amu
total = ∑ molecular mass of compound
= H amu + C amu + Namu
= 1.008 amu + 12.011 amu + 14.007 amu
= 27.026 amu
%H = (1.008amu/27.026amu)100% = 3.730%
%C = (12.011amu/27.026amu)100% = 44.442%
%N = (14.007amu/27.026amu)100% = 51.827%
Check results ∑%values = 100%
3.730% + 44.442% + 51.827% = 99.999% ≅ 100%
distillation, magnetic attraction, filtration
Answer:
The answer is absolutely D!
Jellyfish do have a digestive system because they eat a ton so A is not true
Jellyfish CAN survive in fresh water because they can be kept in fresh water aquariums so B is not true
Jellyfish ARE made of cells because it is a living creature and that is all the proof you need XD so C is also not true
That leaves you with your answer: D
Please Mark Brainiest
10.034 mJ = 1.0034 cJ
0.05 cm = 0.5 mm
0.0325 kJ = 3250 cJ
0.42101 Gg = 421.01 Mg
0.12907 cm = 1.2907 mm
5600.4 Ms = 5.6004 Gs
Hope this helps!
