Solute is a substance that dissolves in a solvent in order to form a solution. Solutes can be in liquid, gaseous or solid phase. Normally, in a solution, solutes are in a lesser amount than the solvents. When a solution has the maximum amount of solutes it can dissolve, then the solution is said to be saturated.
Oxygen can be separated by heating certain oxygen compounds by electrolysis or by liquefying air.
The mass of an ink pen is constant no matter what instrument you use. If you weigh the ink pen on a simple platform balance, it would weigh <em>approximately 16 grams</em>. To measure this mass using a triple beam balance, follow these instructions:
1. Empty the pan, then move the three sliders on each of the beams to left ton the zero mark.
2. Place the ink pen on the pan. As a result, the beams are no longer on the zero mark. Slide the beams until the pointer is at zero.
3. To read the weight, add all the numbers in the three slider beams.
Answer:
electron revolving in a shell is associated with a definite amount of energy. The energy changes when it jumps to another shell that is so say when it goes from one level of energy level to another. Thus shell also gives the energy of a electron besides its location and are therefore called energy levels.
