Ethanol, C2H5OH, is manufactured on a large scale for a wide range of uses such as alcoholic drinks, as an industrial solvent and as a raw material for the synthesis of many organic compounds. Ethanol, C2H5OH, is manufactured on a large scale by two methods: • Fermentation, using yeast, of sugars, such as glucose, C6H12O6. C6H12O6(aq) 2C2H5OH(aq) + 2CO2(g) The ethanol is then distilled off. • Hydration of ethene, C2H4, with steam in the presence of an acid catalyst. C2H4(g) + H2O(g) C2H5OH(g) Compare the sustainability of these methods of manufacturing ethanol in terms of: • availability of starting materials and energy requirements; • atom economy. In your answer, you should make clear how the atom economy of the processes links with chemical theory.
Answer:
See explanation
Explanation:
In considering the sustainability of the two processes, we must remember that fermentation involves the use of sugars as raw materials. These sugars are grown naturally as plants from which sugars are extracted for the fermentation process. This is a sustainable process because sugar is a renewable resource.
On the other hand, ethene is produced from the cracking of fractions obtained from distillation of natural gas and oil. Natural gas and oil are not renewable resources hence the process is not sustainable. The cracking of ethene requires a lot of energy compared to the fermentation of sugar.
As regards atom economy, the cracking of ethene, C2H4(g) + H2O(g) ------> C2H5OH(g) has a better atom economy compared to the fermentation of sugar; C6H12O6(aq) -------> 2C2H5OH(aq) + 2CO2(g).
Atom economy has to do with the process of designing reactions in such a way that atoms which are in the starting materials end up in the final product and not as waste materials.
Fermentation produces a waste material which is CO2 while the cracking of ethene produces no waste material. All atoms of the reactants are converted into atoms of products.
Hence, the cracking of ethene displays 100% atom economy. This implies that all reactant atoms are found in the desired product.

A sample of CO2 gas has a volume of 2.7 L at 78.5 kPa. At what pressure would this sample of gas have a volume of 4.0L? Temperature is constant
Answer:
52.99 kPa
Explanation:
Initial volume V1 = 2.7 L
Initial Pressure P1 = 78.5 kPa
Final Volume V2 = 4.0L
Final Pressure P2 = ?
Temperature is constant
The relationship between these quantities is given by the mathematical expression of Boyles law. This is given as;
V1P1 = V2P2
P2 = V1P1 / V2
P2 = 2.7 * 78.5 / 4.0
P2 = 52.99 kPa

Determine how many moles of water (H2O) are formed from the combustion of 7.50 x 1023 molecules of propane (C3H8). 1 C3H8 (g) + 5 O2 (g) ⟶ 3 CO2 (g) + 4 H2O (g)
Answer:
4.98 moles of H₂O
Explanation:
The balanced chemical equation for the combustion of propane is:
C₃H₈ (g) + 5 O₂ (g) ⟶ 3 CO₂ (g) + 4 H₂O (g)
That means that 1 mol of propane (C₃H₈) produces 4 moles of water (H₂O).
We know that 1 mol is equal to 6.022 x 10²³ molecules. So, we convert the molecules of propane to moles as follows:
7.50 x 10²³ molecules C₃H₈ x 1 mol/6.022 x 10²³ molecules = 1.245 mol C₃H₈
Now, we use the stoichiometric ratio 4 mol H₂O/1 mol C₃H₈ derived from the chemical equation to calculate the moles of water produced:
1.245 mol C₃H₈ x 4 mol H₂O/1 mol C₃H₈ = 4.98 mol H₂O

The half-life of a strontium isotope is 25 years. How much of this particular isotope will remain after 100 years if the starting mass is 16 grams?
Answer:
1 gram
Explanation:
Half life = 25 years
Starting mass = 16 grams
Time = 100 years
Number of half lives = Time / Duration of Half life = 100 / 25 = 4
After first Half life;
Remaining mass = 16 / 2 = 8 g
After Second Half life;
Remaining mass = 8 / 2 = 4 g
After Third Half life;
Remaining mass = 4 / 2 = 2 g
After Fourth Half life;
Remaining mass = 2 / 2 = 1 g
3. You believe that water boils at 212 degrees Fahrenheit (100 degrees Celsius). Write the numberon the scale from best to worst.
1. Your cousin said that he tested the temperature of water boiling and found that it was 100°C.
2. Most people you know believe that water boils at 100°C.
3. You used a thermometer to measure the temperature at which water boiled. You repeated the experiment 3 times. Each time the thermometer read 100°C.
4. You read an article in a science journal from 50 different labs around the world that have tested the temperature of water and found that it boils at 100°C in every location.
You come across an article in a scientific journal from 50 different laboratories around the globe that measured the boiling point of water and discovered that it is 100°C everywhere.
What transpires when water is heated to 100 C (This is 212 F)?Water turns into gas around 212°F (100°C), which is the temperature at which it begins to boil (water vapor). Pressure affects the melting/freezing and boiling points. Water's boiling point changes when air pressure changes. The boiling point decreases with increasing altitude or decreasing pressure.
At 212 degrees Fahrenheit, does water boil, or at 100 degrees?Water has a freezing point of 32 degrees Fahrenheit and a boiling point of 212 degrees Fahrenheit on the Fahrenheit scale.

balance the following formula equation Al(s) + CuCl2 (aq) = AICI3 (aq) + Cu(s) Coloress
Answer:
[tex]2Al (s) + 3CuCl2( aq) --> 2AlCl3 (aq) + 3Cu(s)[/tex]
Explanation:
The main thing for this equation is to follow the amount on each side. Count each element on each side. Then by looking at the numbers figure out what numerical digit would make them equal.
For example:
On the left we have
Cu=1 and Cl=2.
But on the right we have
Cu=1 and Cl=3.
In order for them to be the same, we must add a coefficient of 3 to CuCl2 (aq0 on the left and a coefficient of 3 to Cu(s) on the right.

17. 50% chances of round offspring
18. 25% chances two copies of dominant allele in the genotype of offspring
Explanation:
17. In this question it is stated that the Spongebob is heterozygous and has a square body which means the square body is dominant over the round that is present in sponge Susie that means she has two copies of the recessive allele.
S for square trait and s for a round trait then
S s
s Ss ss
s Ss ss
Thus, the correct answer is 50 percent as there are only two copies of ss.
18. in this question Patric and Patti both have heterozygous for the pink (P) body-color dominant over yellow (p). The chances for the true-breeding dominant genotype would be -

D Add a catalyst
Answer:
d.) add a catalyst
Explanation:
ae per I know this is Ur , but I am not sure so u check it
B. Reduce the concentration of a reactant
A chemical reaction is a process that leads to the chemical transformation of one set of chemical substances to another.When the surface area of reactants is more the sites available for the collisions increase. More collisions between the reactants increases the rate of a chemical reaction. Decreasing the surface area of reactants decreases available site for collision. This eventually decreases the rate of a chemical reaction.To decrease the rate of a chemical reaction, B. Reduce the concentration of a reactantFor more information:

Answer:
Oxygen is relatively insoluble in water
Explanation:
Answer: Yes
Explanation:
Oxygen is relatively insoluble in water, its solubility being only 264 µM at 25 °C. That explains in part why you (and fish) require dedicated oxygen carriers in your blood to transfer sufficient oxygen around your body.

How are the atoms of carbon different from the atoms of nitrogen
Per my research, it was said that each of the atoms of the carbon has over 6 protons, six neutrons, and 6 protons. Each atom of nitrogen has 7 protons, 7 electrons, and 7 neutrons. The atomic mass of carbon and nitrogen is 12 and 14 respectively. As the number of electrons in the atoms of the two elements is different they have different chemical properties.
Explanation:As you may know, I did my research and this is what it gave me. I would suppose it is correct since it explains that the carob has over 6 protons and so on. Correct me if I am incorrect and I hope this helped. Have a good one!
