<span>So to make it clear let's break the equation down species by species and assess the number of each species on bothe sides of the equation:
2C</span>₈H₈ + 25O₂ → 8CO₂ + 18H₂<span>O
LHS: C - 16 RHS: C - 8
H - 16 H - 36
O - 50 O - 34
Thus based on that it is evident that the equation is not quite balanced. This therefore means a "</span><span>No, because the number of carbon, hydrogen & oxygen atoms on both sides of the equation are not equal."
</span>The actual balance equation would be C₈H₈ + 10O₂ → 8CO₂ + 4H₂O
A, true is the answer and cluke u help me please
Molar mass H₂O = 18.0 g/mol
number of moles :
1.0 / 18.0 => 0.055 moles
1 mole -------------- 6.02 x 10²³ molecules
0.055 moles -------- ? molecules
molecules = 0.055 x ( 6.02 x 10²³) / 1
molecules = 3.311x10²² / 1
= 3.311 x 10²² molecules
hope this helps!
Vapor pressure is the pressure which is exerted by the vapors of a liquid in equilibrium with the liquid. Vapor pressure depends on the boiling point; lower the boiling point higher will be the vapor pressure.
Based on the given compounds:
rubbing alcohol is polar and has the strongest intermolecular force of attraction followed by relatively polar ether and finally the non-polar propane.
The increasing order of boiling point will be:
propane < diethyl ether < rubbing alcohol
Thus, the increasing order of vapor pressure will be:
rubbing alcohol < diethyl ether < propane
