Is mixing flour and rubbing alchohal a physical or chemical?
Mixing flour and rubbing alcohol is a physical change. In this process, the flour and rubbing alcohol retain their individual properties and can be separated again. There is no chemical reaction occurring, as the composition of the flour and the rubbing alcohol remains unchanged.
Can you substitute rubbing alcohol for oil in perfume and it still smell strong?
Rubbing alcohol can be used as a substitute for oil in perfume, but it may change the final scent and consistency of the perfume. Rubbing alcohol evaporates quickly, which may affect the longevity and intensity of the perfume scent. It is recommended to use perfumer's alcohol or a carrier oil for better results.
What are the ingredients in isopropryl rubbing alcohol?
Rubbing alcohol contains two ingredients. One is isopropanol (also called isopropyl alcohol or propan-2-ol), which has C3H7OH as its chemical formula. The other ingredient is water. The rubbing alcohol sold in pharmacies is typically 70% isopropanol by mass and 30% water. It also comes as a 91% isopropanol. The 70% is actually a better disinfectant.Ethyl alcohol is also available as a rubbing alcohol, and is a smaller molecule than isopropanol.Also note that rubbing alcohol that is bought over the counter, especially in the US, is adulterated with all sorts of other molecules, such as benzene and methanol. This is done to keep people from drinking them. (In the US, they are added so that they can be sold without a liquor license.)Read more: What_are_the_ingredients_in_rubbing_alcohol
Why does rubbing alcohol have a higher heat capacity then water?
Rubbing alcohol, primarily composed of isopropyl alcohol, has a higher heat capacity than water due to its molecular structure and bonding characteristics. The presence of hydrogen bonds in water allows it to store heat effectively, but isopropyl alcohol has a lower density and fewer hydrogen bonds, which affects its ability to absorb heat. Additionally, the specific heat capacity of a substance is influenced by its mass and the energy required to change its temperature, making the heat capacity of rubbing alcohol relatively higher in certain contexts, despite water’s overall higher heat capacity per unit mass.
What effect does ethanol have on the boiling point of water?
The pure ethanol has the boiling point 78.5 celsius while water has 100 celsius so when water is added to ethanol its boiling point becomes increased.

Is rubbing alcohol that evaporates on your hand a physical change?
It is a physical change. The molecules of the alcohol are still there, there are just spread out.
What happens when food coloring is added to alcohol?
Drinking alcohol: It will change the alcohol's color or taste Rubbing alcohol: It will most likely change the effects that the alcohol has on the substance on which it is applied to. It may change the color of the substance it is applied to.
Can you Make rubbing alcohol drinkable?
No. Rubbing alcohol is a type of alcohol called Isopropyl Alcohol (or isopropynol). Drinking alcohol is ethyl alcohol (or ethynol). They are different at a molecular level, which means you would have to add and remove atoms to change them. You are about as likely to do this as to turn your charcoal for your BBQ into diamonds at home.
What chemical reaction that absorbs heat called?
Endothermic reactionFor endothermic reactions Hfinal > Hinitial and DH is positive (+DH)It can be for example melting ice, or vaporising Rubbing Alcohol.---------Change of phases are not chemical reactions !
How does rubbing alcohol expire and what are the signs to look out for?
Rubbing alcohol can expire due to evaporation of the alcohol content over time. Signs to look out for include a change in color, a strong or unusual odor, or a decrease in effectiveness. It is important to check the expiration date on the bottle and discard if expired.

What happens when you ignite rubbing alcohol?
Rubbing Alcohol will evaporate at about 37 COr about 98.6 FRubbing alcohol (isopropyl alcohol) will begin to evaporate at temperatures above -175 degrees F. It is a very volatile substance, It evaporates faster at warmer temperatures.
What is endothermic change?
endothermic change is a change, in which heat from outside is observed by reactants, leaving the surrounding cooler. Examples are evaporation of water, alcohol and dissolving glucose in water.
Will rubbing alcohol change the color of your hair?
Yes I used isopropyl witch has acohol in it and my hair was brown and now it is blond 😏🙈😁
How long do you leave rubbing alcohol in hair to dye it?
Rubbing alcohol is not recommended for dyeing hair as it can be drying and damaging to the hair and scalp. It is best to use hair dyes or semi-permanent color products specifically made for hair dyeing. If you are looking to temporarily color your hair, consider using hair chalk or temporary hair dyes.
