Ethanol is a general term for the chemical compound with the formula C2H5OH, commonly known as alcohol. Absolute ethanol refers to ethanol that is at least 99% pure, with the remaining percentage being water. Absolute ethanol is often used in scientific and industrial applications where purity is critical.
technical grade is bethween 96% and 98% ethanol and ethanol absolute means pure ethanol whithout water ('almost') 99.9% ethanol Absolute ethanol has no water whereas 96% ethanol has 4% water or 98% has 2% water. Thus, the reaction can occur with water.
There is no difference between ethyl alcohol and ethanol, they are the same substance. Ethanol is the chemical name for the alcohol commonly found in beverages and used in industry.
The polarity difference between ethanol and water affects their interactions in a solution because water is a polar molecule with positive and negative charges, while ethanol is also polar but less so. This difference in polarity allows ethanol and water to mix well together, forming a homogeneous solution. The positive and negative charges in water attract the ethanol molecules, leading to strong interactions between the two substances.
The main difference between ethanol and methanol is in their chemical structures. Ethanol, also known as ethyl alcohol, has two carbon atoms whereas methanol, also known as methyl alcohol, has one carbon atom. Ethanol is commonly found in alcoholic beverages, while methanol is used as a solvent and fuel. Methanol is more toxic to humans compared to ethanol.
The main difference between methanol and ethanol is their molecular structures. Methanol has one carbon atom, one oxygen atom, and three hydrogen atoms, while ethanol has two carbon atoms, one oxygen atom, and five hydrogen atoms. Additionally, methanol is more toxic to humans compared to ethanol.
Methanol is CH3OH while ethanol is C2H5OH. The difference is CH2.

To prepare 95% ethanol from absolute ethanol, you would need to dilute the absolute ethanol with a calculated amount of distilled water. Since absolute ethanol is 100% pure, you can use the formula C1V1 = C2V2, where C1 is the initial concentration (100%), V1 is the volume of absolute ethanol, C2 is the desired concentration (95%), and V2 is the final volume of the diluted solution. By rearranging the formula and solving for V1, you can determine the volume of absolute ethanol needed to achieve a 95% ethanol solution when mixed with water.

The absolute difference is 1.
To find the percent difference between two numbers, you first calculate the absolute difference between the two numbers. In this case, the absolute difference between 1419 and 1286 is 133. Next, you divide this absolute difference by the average of the two numbers (1352.5) and multiply by 100 to get the percent difference. Therefore, the percent difference between 1419 and 1286 is approximately 9.82%.
The polarity difference between ethanol and water affects their interactions in a solution because water is a polar molecule with positive and negative charges, while ethanol is also polar but less so. This difference in polarity allows ethanol and water to mix well together, forming a homogeneous solution. The positive and negative charges in water attract the ethanol molecules, leading to strong interactions between the two substances.
Vodka has 40% ethanol in it, water doesn't.

An absolute threshold is the smallest amount of stimulation needed for a sensation to be detected, while a just noticeable difference is the smallest detectable difference between two stimuli. In other words, the absolute threshold is about detecting the presence of a stimulus, while the just noticeable difference is about discriminating between two stimuli.
