Clear dots form.. then you can see the dots under light..
still white, egg shell decreases!
A molecule of ethanol has 2 carbon atoms, 6 hydrogen atoms and 1 oxygen atom. Their atomic masses are 12, 1 and 16 respectively. Therefore, the molecular mass of ethanol is 12x2+6x1+16=46u.
One is that it is quite flammable. It's not clear what chemical properties you mean however. It is called isopropyl alcohol, isopropanol, or 2-propanol, or propan-2-ol. It's chemical formula is C3H8O As regards its physical properties, it is a clear liquid, with a strong odor. It is also fairly volatile (evaporates easily). It's molar mass is 60.10 g/mole, it's density is .785 g/cm3, its melting point is -89 °C and its boiling point is 82.3 °C.It is completely soluble (miscible) in water, ethanol, ether, acetone and toluene, and slightly soluble in brine,For more information, see the Web Links to the left of this answer.
What acid, what mass (not volume!) what alcohol, what mass of that alcohol (not volume!)
The alcohol is cooked of and loses density in the liquid. Because the liquid becomes less dense, the mass goes down. (Unless you are talking about pure alcohol)
The molar mass of the lightest alcohol, methanol, is 32.04 grams per mol. No alcohol has a molar mass of 4.75 grams. To find the molar mass of a substance, you sum the mass of every atom that makes up your compound. For methanol, you add the mass of three hydrogens, a carbon, and an oxygen atom. An alcohol group, more properly a "hydroxyl," consists of an oxygen and a hydrogen and contributes about 17 grams per mol to the molar mass (about 16 g/mol for an oxygen atom and 1 for a hydrogen). Hope this helps!
Water. It has a higher density. The density of water is 1 g/cm3 and the density of rubbing alcohol is .786 g/cm3
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
If you filled a 1L bottle with water and another 1L bottle with rubbing alcohol, which bottle would feel heavier? Use your data to thoroghly explain why. The rubbing alcohol would be heavier because water's density is 1.0, and rubbing alcohol's density is much more than that. Right???

The general formula of ethyl alcohol is : C2H6O and its molar mass is ( 2x12)+(6x1) +(1x16) = 46. Thus C% = (24/46)x100= 52.17%, H%=(6/46)x100= 13.04%, and O%=(16/46)x100=34.78%.

The mass of isopropyl alcohol is 60.1g

If the mass of an object increases, what happens to the acceleration?
It is prepared from a special denatured alcohol solution and contains approximately 70 percent by volume of pure, concentrated ethanol (ethyl alcohol) or isopropanol (isopropyl alcohol), so approximately 35 mL in a 50mL bottle.
what happens is the mass stays the same because of the law of conservation of mass
The alcohol is cooked of and loses density in the liquid. Because the liquid becomes less dense, the mass goes down. (Unless you are talking about pure alcohol)
