Question
Chapter 1, Problem 59SA
Summary Introduction
To review:
Amongst carbon dioxide (CO2) or ethanol (CH3CH2OH), the molecule that contains more energy is to be explained.
Introduction:
The stability of a molecule depends upon the number of electrons share within the covalent bond. Energy is released by the molecule depends upon the number of electrons it can dissociate and release as free ions.

Hydrocarbons with 5 carbons (pentane) and 19 carbons (nonadecane) are liquids
at room temperature. The molecules with 8, 9, and 10-carbons are "octane",
"nonane", and "decane" and are common components of gasoline. The image
below shows chemical equations for the combustion of the simplest
hydrocarbon methane, 3-carbon propane, and 10-carbon decane. As you can
see, the products are always carbon dioxide and water, just in larger amounts for
larger hydrocarbons. Question: how many carbon dioxide molecules are formed
from combustion of one molecule of decane?
Methane
CH4 + 202 → CO2 + 2H2O
Propane
C3H3 +502 –
→ 3CO2+4H2O
C10 H22 + 15.502
10CO2 + 11H20
Decane

Another fossil-fuel gas used in cooking appliances is "propane", used commonly
in backyard grills and RV/camping stoves. Propane is a bigger hydrocarbon: 3
carbons single-bonded in a chain, and the remaining bonds are taken by
hydrogen. Its formula is C3H8 and its structure is shown below. KEY POINT: the
products are the same as the combustion of methane, but more is produced.
The graphic below shows that one propane molecule reacts with 5 oxygen
molecules to form
molecules of carbon dioxide.

- In H2O how many hydrogen (h) atoms are presentarrow_forwardWhich of the following correctly explains why the vapor pressure of water has to be included in the calculations? Some of the liquid water evaporates into the gas, and increases the total pressure generated by the trapped gas. As the H2(g) is bubbled up the reaction solution, some of the H2(g) molecules are solubilized by water in the aqueous solution, effectively decreasing the measured pressure above. The pressure contributed by the H2(g) is greater than the measured total pressure because of the contribution of partial pressure of water vapor. The pressure exerted by the evolved H2(g) is reduced because of the co-presence of water vapor, thus Pwater vapor has to be added to Pdry gas.
