Nitrogen and hydrogen atoms that make up ammonia (NH3) are held together by polar covalent bonds, where electrons are shared unequally. Nitrogen is significantly more electronegative than hydrogen, so shared electrons spend more of their time orbiting the nitrogen atom.

Answer:
N=35%. so 35/100*7 =2.45%
H=5.0 so 5/100*1=0.05%
o=60% so 60/100*8=4.8%

Answer:
The correct answer is = 31.04
Explanation:
The relation between volume, temperature and pressure of a fix amount of a gas can be expressed by the combined gas law:
PV/T = k
It can be written as well as
P1V1/T1 = P2V2/T2
Given:
V1 = 217.6
P1 = 9.011 atm
T1 = 127.8°C = 400.95 K
P2 = 44.9
T2 = 11.9 °C = 285.05
Solution:
Putting value in the formula
V2 = P1V1T2/P2T1
= (217.6*285.05*9.011)/44.9*400.95
V2 = 31.04
