Who first studied component colors of sunlight?
Isaac Newton is credited with first studying the component colors of sunlight through his experiments with prisms in the 17th century. He demonstrated that sunlight is composed of different colors that can be separated and recombined to form white light.
How can recrystallization separate a mixture?
Recrystallization separates a mixture by taking advantage of differences in solubility between the components. By dissolving the mixture in a suitable solvent at an elevated temperature, the less soluble component will precipitate out first as the solution cools, forming pure crystals. The more soluble component remains dissolved in the solution and can be separated from the crystals through filtration.
What happens to the particles in distillation?
In distillation, the particles in a liquid mixture are separated based on their boiling points. When the mixture is heated, the component with the lower boiling point vaporizes first, rises, and condenses back into a liquid in a separate container. The remaining components are left behind in the original container.
How can petrol and kerosene be separated from each other when they are mix together and the difference between their boiling points is 25 degree celsius?
Petrol and kerosene can be separated by a process called fractional distillation. Since there is a 25-degree Celsius difference in their boiling points, they can be heated, and the component with the lower boiling point (in this case petrol) will vaporize first and can be collected separately, leaving kerosene behind.
How do you separate gases the air?
The best process for the separation of components of air is fractional distillation of air. The process includes the liquefaction of air first and then distillation of various fractions on the basis of different boiling points. By using this process, all the components of air can be separated out.
How do you separate iodine and methyl alcohol?
Iodine and methyl alcohol can be separated by fractional distillation, as they have different boiling points. Methyl alcohol has a lower boiling point than iodine, so it will vaporize first and can be collected separately.

When was the movie Independence Day first screened in America?
It made its first air on July 2, 1996.
What was the first screened photosensitive metal plate?
The first screened photosensitive metal plate was the heliograph, invented by Joseph Nicéphore Niépce in 1826. This process used bitumen of Judea on a metal plate that hardened when exposed to light, creating the first permanent photograph.
Who first studied component colors of sunlight?
Isaac Newton is credited with first studying the component colors of sunlight through his experiments with prisms in the 17th century. He demonstrated that sunlight is composed of different colors that can be separated and recombined to form white light.
What date was calcium discovered?
Calcium was known to be a component in lime during Roman times, but was first separated from it in 1808 by Sir Humphrey Davy via electrolysis.
What is the name of CH2CHCH2CH2CH3?
In this molecule you have 2 different carbon chains separated by the functional ether group. The generic formula for an ether is R-O-R. Your first group is a 2 carbon chain called an ethyl and your second group is a 1 carbon called a methyl. So you have a methyl group and ethyl group which must be put together in in alphabetical order ethyl-methyl and then followed by the functional group -ether. Thus your final molecule name is ethyl-methyl-ether. Good luck with the rest of O. Chem!
