What else can I help you with?
How does one prepare 500ml of 70 percent ethanol?
150 ml ethanol to 350 ml distilled water
Is distance ratio or interval?
It is ratio.
What is the product of the numerator of one ratio and the denominator of the other ratio called in a proportion?
The numerator of the second ratio and the denominator of the first ratio are called the means, and the numerator of the first ratio and the denominator of the second ratio are called the extremes. The product of the means equals the product of the extremes.
There are two rectangles what are the ratio of the first to the second?
I guess you mean the ratio of the areas; it depends if the 2 rectangles are "similar figures"; that is their matching sides are in the same ratio. If they are similar then the ratio of their areas is the square of the ratio of the sides.
How do you express ratio?
You express ratio as a fraction. For instance, the ratio of 3 to 4 is 3/4, or .75
What is the Ratio of carbon in ethanol?
2/9 in terms of atoms.
How do you make nitrocellulose thinner what are the solvents and the ratio?
Nitrocellulose is soluble in a mixture of ethanol and ethylether.
Is ethyl alcohol soluble in water?
Yes, ethanol (ethyl alcohol), as being a fluid by itself, is in any ratio miscible with ('soluble in') water.At 96% ethanol the mixture has the lowest boiling point, so destillation of a water-ethanol will never give a higher ethanol content.
How is ethanol made for cars?
Ethanol is alcohol made from corn/sugar cane, etc. it is the same alcohol you drink. Cars that run on ethanol, have different fuel lines, injectors, ECU programming since ethanol runs at a different ai/fuel ratio than gasoline.
What is the boiling point of ethanol-water mixtures?
The boiling point of ethanol-water mixtures varies depending on the ratio of ethanol to water. Generally, the boiling point of these mixtures falls between the boiling points of pure ethanol (78.37C) and pure water (100C). The boiling point increases as the ethanol content in the mixture increases.
How much does a gasoline ethanol blend weight per gallon if the ratio per gallon is 90 percent gasoline and 10 percent ethanol?
Around 6 lbs. Depends on temperature and elevation.
The pH of ethanol?
the pH of ethanol can be calculated using its pKa value (pKa 15.9) and the Henderson-Hasselbalch equation. pH = pKa - log [AH/A] where [AH/A] the ratio of disassociated versus undisassociated species in solution.
Does your gas tank have to be completely empty when refueling with E85 due to the ethanol and gasoline ratio?
No. Just fill as normal at any point.
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.
Explain why during the recrystallization of p-dibromobenzene the turbidity of the hot solution was used as an indicator for the ratio of ethanol to water used?
ethanol alone is not a good solvent for this substance recrystallization and the compound has a very low solubility in hot or cold water.so ethanol and water are mixed together as solvent for crystallization of p-dibromobenzene that is soluble in the hot solvent mixed.so the turbidity of the hot solution shows the good mixture of ethanol and water as solvent.
What is the optimal ratio of sugar corn water and yeast to make ethanol?
You need a minimum of one yeast organism (which is microscopic). If you start with a very small amount of sugar, water, and yeast, you will wind up with a very small amount of ethanol. It's very logical.
Calculate the molarity of a solution of ethanol in water in which the mole fraction is 0.040 assume that the density of water to be one?
It depends a bit on what information you are given. However, the principle is the same in all cases, although how you do the specific calculation may vary a bit.As an example, let's say we have a mixture of 5.00 grams of water and 10.0 grams of ethanol (C2H5OH). What is the mole fraction of the two components?The first thing we must do is convert the number of grams of each substance into moles. To do that, see the Related Question below:How do you convert from grams to moles and also from moles to grams?For water, we have:5.00 grams ÷ 18.015 grams/mole = 0.2775 moles H2OFor ethanol, we have:10.0 grams ÷ 46.068 grams/mole = 0.2171 moles C2H5OHNow we can find the mole ratio, which is defined as follows:Moles ratio of compound X = number of moles of X ÷ total number of moles in mixtureSo the mole ratio of water is: 0.2775 ÷ (0.2775 + 0.2171) = 0.561 or 56.1%and the mole ratio of ethanol is: 0.2171 ÷ ((0.2775 + 0.2171) = 0.439 or 43.9%Check your answer! The total mole ratio for all components MUST add up to 1.00:0.561 + 0.439 = 1.00 Yes!Note that the weight ratio was 1-to-2 (twice as much ethanol as water by weight), but the mole ratio was completely different.
