B) land cools off much faster than water (creating a air region of high density above land and lower density above sea)
Answer:
Oxygen
Explanation:
Oxygen has 6 valence electrons and it wants to have 8 to obtain a stable octet. So Oxygen gains two electrons in the bond, developing an anion.
It is also a non-metal, and they tend to gain anions.
2C₃H₇OH + 9O₂ = 6CO₂ + 8H₂O
V(O₂)=12.0 dm³
n(C₃H₇OH)=0.1 mol
n(O₂)=12.0 dm³/22.4 dm³/mol=0.5357 mol
C₃H₇OH : O₂ 2:9 1:4.5
0.1:0.5357
oxygen in excess
V(CO₂)=3Vm*n(C₃H₇OH)
V(CO₂)=3*22.4*0.1=6.72 dm³
