Answer: The net chemical reaction:
Explanation:
Step 1 : Propane reacts with water to form carbon monoxide and hydrogen gas
...[1]
Step 2 : carbon monoxide formed in above step reacts with water tio form hydrogen gas and carbon dioxide.
...[2]
On Adding [1] and 3 × [2] we get overall balanced chemical reaction for the production of hydrogen from propane and water:
1 mole of propane reacts with 6 moles of water vapor to gve 10 moles of hydrogen gas and 3 moles of carbon dioxide.
Start by balancing the hydrogen atoms. There are 9 on the reactants side and 2 on the products side. The least common multiple of 9 and 2 is 18, so the coefficient for C5H9O should be 2 and the coefficient for H2O should be 9.
Next, balance the carbon atoms. After giving C5H9O a coefficient of 2, there are 2*5, or 10 carbon atoms on the reactants side. There is only 1 carbon on the products side. The least common multiple of 1 and 10 is 10, so the coefficient of C5H9O remains as 2 and the coefficient for CO2 becomes 10.
Lastly, balance the oxygen atoms. With C5H9O having a coefficient of 2, there are 4 oxygen atoms on the reactants side. With CO2 having a coefficient of 10 and H2O having a coefficient of 9, there are 29 oxygen atoms on the products side. Here, you balance by changing only the coefficient of O2, which currently provides 2 oxygen atoms to the reactants side. 2 of the 29 oxygen atoms are covered by C5H9O, so the O2 needs to cover for the other 27. Every mole of O2 has 2 oxygen atoms, so the coefficient should be 27/2, or 13.5. We don't want decimals in the reaction, so multiply all of the coefficients by two. This gives the balance reaction:
4C5H9O + 27O2 --> 20CO2 + 18H2O
Answer:
Fossil fuels are hydrocarbons, primarily coal, fuel oil, or natural gas, formed from the remains of dead plants and animals. In common dialogue, the term fossil fuel also includes hydrocarbon-containing natural resources that are not derived from animal or plant sources.
Explanation:
fossil fuels are continually formed by natural processes, they are generally classified as non-renewable resources because they take millions of years to form, and known viable reserves are being depleted much faster than new ones are generated.
Answer:
a. NADH, FADH2
b O2
c. ATP, H2O
Explanation:
The reduced coenzyme that is generated in the citric acid cycles are NADH and FADH2. These coenzymes feed electrons in the electron transport chain which moves through electron acceptors present in the ETC.
The final electron acceptor in the electron transport chains is oxygen which converts into H2O. This movement of electron through ETS allows the movement of H+ ions from the mitochondrial matrix to intermembrane space.
These H+ ions when it comes back in the matrix through ATP synthase it generates ATP. So ATP and H2O are the final products of ETC and oxidative phosphorylation.
ΔS = 0.250 J·K^(-1)
<em>Step 1</em>. Calculate the <em>moles of CO</em>
From the<em> </em><em>Ideal Gas Law</em>,
<em>n</em> = (<em>pV</em>)/(<em>RT</em>) = (8.00 kPa × 3.00 L)/(8.314 kPa·L·K^(-1)·mol^(-1) × 298.15 K)
= <em>0.009 682 mo</em>l
Δ<em>S</em> = <em>nC</em>_Vln(<em>T</em>_2/<em>T</em>1)
= 0.0096 82 mol × 20.17 J·K^(-1)mol^(-1) ln(1073.15 K/298.15 K)
= 0.1953 J·K^(-1) × ln3.599 = 0.250 J·K^(-1)
