Compare the Elements
Elements are chemically the simplest substances and hence cannot be broken down using chemical methods. Elements can only be changed into other elements using nuclear methods. Although an element's atoms must all have the same number of protons, they can have different numbers of neutrons and hence different masses . When atoms of the same element have different numbers of neutrons, they are called isotopes . An element is a substance consisting of atoms which all have the same number of protons - i.e. the same atomic number. With only one proton, hydrogen is the simplest, lightest element, followed by helium, which has two protons. The Most Abundant Elements At 75 percent, hydrogen is also the most abundant element in the universe, followed again by helium at 23 percent, then oxygen at 1 percent. Each oxygen atom has eight protons. All of the other elements make up the remaining 1 percent. In the earth's cru...
Hi zelvy, please explain about definition of the colligative proporties solution? thanks
BalasHapusColligative properties are properties of solutions that depend on the ratio of the number of solute particles to the number of solvent molecules in a solution, and not on the nature of the chemical species presen
HapusCan you give example for osmotic ? Thanks
BalasHapusAn example of the osmotic pressure in everyday life is the entry of ground water into the crop through the root cell. An osmosis event will create an osmotic pressure
HapusExplain the nature of the colligative and give an example
BalasHapusThe colligative nature of the solution is the properties that depend only on the quantity of solute particles in the solution and does not depend on the type or identity of the solute particles - no matter in the form of atoms, ions, or molecules.
HapusFor example
Steam Pressure Decrease
Boiling Point Increase
Decrease of Freezing Point
Osmosis Pressure
Can you explain colligative with understanding, example you can show not just theorical, but practical?
BalasHapuszelvy, What do you know about osmotics?
BalasHapusThe osmotic pressure is the hydrostatic pressure that forms in the solution to stop the solvent osmotic process into the solution through a semi-permeable membrane.
HapusAs mentioned, the amount of external pressure (osmotic pressure) is equal to the pressure to perform the osmosis.
