I mean this is pretty obvious it's D. life expectancy is sort of close but not really. B is close too but it's not it bc that's not what health is. you could be over weight and not be sick and it still isn't healthy. and C isn't close at all. hope this helps, have an amazing day :)
Answer:
0.6364 g/cm^3
Explanation:
Density = mass/volume
Where mass = 5.6g and...
Volume = (33.9 - 25.1) = 8.8ml
Where 1ml = 1 cm^3
Density = 5.6/8.8 = 0.6364 g/cm^3
Looking for the atom which has the smallest valence p atomic orbital among the choices (carbon, nitrogen, sulfur) requires one to look at a periodic table with electron configurations. The answer is carbon. It's p orbital only has 2 electrons. (Full configuration of carbon: 1s2 2s2 2p2) (Nitrogen has 2p3 while sulfur has 2p4.)
The reaction between sodium hydroxide and ammonium sulfate generates ammonia gas along with water and aqueous sodium sulfate. The reaction can be shown as follows:
2NaOH(aq) + (NH4)2SO4(aq) → 2NH3(g) + Na2SO4(aq) + 2H2O(l)
The reaction can be further simplified to give a net ionic equation as:
2Na+(aq) + 2OH-(aq) + 2NH4+(aq) + SO42-(aq) →
2NH3(g) + 2Na+(aq) + SO42-(aq) + 2H2O(l)
Net ionic:
OH-(aq) + NH4+(aq) ↔ NH3(g) + H2O(l)
