To calculate the amount of glucose needed to form 124 grams of ethanol, you need to use stoichiometry. The molecular weight of glucose is 180.16 g/mol and the molecular weight of ethanol is 46.07 g/mol. From the balanced equation for fermentation, 1 mole of glucose produces 2 moles of ethanol. Therefore, you would need 248 grams of glucose to form 124 grams of ethanol.
What else can I help you with?
Is glucose soluble?
Glucose is sparingly soluble in ethanol. This is because the organic molecules of the ethanol are too large to separate the glucose, unlike water where the water molecules are easily able to dissolve the crystalline structure to react with the -OH groups.
How many grams of oxygen will react with 2 mole of ethanol?
The balanced chemical equation for the reaction of ethanol with oxygen to form carbon dioxide and water is C2H5OH + 3O2 -> 2CO2 + 3H2O. From this equation, we can see that 3 moles of oxygen are needed to react with 1 mole of ethanol. Therefore, 2 moles of ethanol will require 6 moles of oxygen to react. To find the grams of oxygen, you can multiply the moles of oxygen by its molar mass (32 g/mol).
What is a dilute form for ethanol?
A dilute form of ethanol is a solution of ethanol in water. It is commonly referred to as alcohol or ethyl alcohol and is commonly used in various applications such as disinfectants, cleaning solutions, and beverages. The concentration of ethanol in a dilute form can vary, with common percentages like 70% or 90% ethanol.
Is dextrose conductive?
No, dextrose is not conductive as it is a type of sugar, specifically a form of glucose. It does not possess the properties required to conduct electricity.
How do you separate ethanol from aqueous ethanol?
Ethanol can be separated from aqueous ethanol through a process called distillation. In distillation, the mixture is heated to evaporate the ethanol, which is then condensed back into liquid form. The condensed ethanol can then be collected as a separate product.
How many moles of glucose are required to form 127g of ethanol?
To form ethanol, the chemical equation shows that one mole of glucose is converted to two moles of ethanol. The molar mass of glucose is around 180 g/mol and that of ethanol is around 46 g/mol. Therefore, to produce 127g of ethanol, you would need 127g/(46g/mol) = 2.76 moles of ethanol. Since glucose to ethanol is a 1:2 ratio, you would need half as many moles of glucose, which would be 1.38 moles of glucose.
What is the heat of reaction for ethanol fermentation from glucose?
The heat of reaction for ethanol fermentation from glucose is exothermic, meaning it releases heat. This is because the process of fermentation involves breaking down glucose to produce ethanol and carbon dioxide, which releases energy in the form of heat.
What are formed when glucose is fermented?
When glucose is fermented, it can form products such as ethanol (alcohol) and carbon dioxide. This process is commonly used in the production of alcoholic beverages and in baking to help bread rise.
Can ethanol C6H12O6 dissolves in water?
Yes, ethanol (C6H12O6) can dissolve in water since it is a polar molecule with a hydroxyl (-OH) group that allows it to form hydrogen bonds with water molecules. This makes ethanol miscible in water, meaning they can mix and form a homogeneous solution.
Is glucose soluble?
Glucose is sparingly soluble in ethanol. This is because the organic molecules of the ethanol are too large to separate the glucose, unlike water where the water molecules are easily able to dissolve the crystalline structure to react with the -OH groups.
What is the most abundant form of carbohydrate?
Glucose is the simplest carbohydrate and so probably the most abundant. It is required by every living cell for energy.
How many grams of oxygen will react with 2 mole of ethanol?
The balanced chemical equation for the reaction of ethanol with oxygen to form carbon dioxide and water is C2H5OH + 3O2 -> 2CO2 + 3H2O. From this equation, we can see that 3 moles of oxygen are needed to react with 1 mole of ethanol. Therefore, 2 moles of ethanol will require 6 moles of oxygen to react. To find the grams of oxygen, you can multiply the moles of oxygen by its molar mass (32 g/mol).
How many molecules of hydrogen are required to form one molecule of glucose?
In the process of photosynthesis, 6 molecules of carbon dioxide react with 6 molecules of water to form one molecule of glucose and 6 molecules of oxygen. Thus, 12 molecules of hydrogen are required to form one molecule of glucose (from the 6 molecules of water).
How does fermantation different from respiration?
Fermentation occurs when there is not enough oxygen available to perform respiration. In respiration, glucose is combined with oxygen to form CO2, H2O, and energy. In fermentation, glucose is broken down into CO2 and ethanol, which releases less energy.
What is a dilute form for ethanol?
A dilute form of ethanol is a solution of ethanol in water. It is commonly referred to as alcohol or ethyl alcohol and is commonly used in various applications such as disinfectants, cleaning solutions, and beverages. The concentration of ethanol in a dilute form can vary, with common percentages like 70% or 90% ethanol.
The body can absorb up to 120 grams of carbohydrate per hour from the small intestine. If we assume this is all in the form of glucose how many moles of glucose have been absorbed?
0.67 moles of C6H12O6
Why does the starch need to be converted into sugar before it is used to make ethanol?
Starch is the storage form of glucose in plants. Glucose is compounded into chians called starch and stored for later use. During times when there is a deficiency of glucose in plant cells, this stored starch can be broken down back into glucose and used in various metabolic processes
