Answer:
Explanation:
The physical methods of separating mixtures are used in sorting a mixture of substances.
It requires no chemical changes occurring between their components and parts in any significant way.
Examples are:
- Decantation
- Filtration
- Sublimation
- Magnetism
- Centrifugation
The methods simply relies on the physical properties of matter.
Organic molecule. In particular, a carbohydrate.
Answer:
decrease
Explanation:
because the equilibrium will shift to right side
Answer:
The amount of gravity they have depends on their size. So, a small planet has less and a larger planet has more gravity. Just like the planets, a person with more mass has more gravity and therefore weighs more.
Answer: 
.
Explanation:
= Wavelength of radiation
E= energy
Using Rydberg's Equation:
Where,
= Wavelength of radiation = ?
= Rydberg's Constant
= Higher energy level = 4
= Lower energy level = 1
Z= atomic number = 1 (for hydrogen)
Putting the values, in above equation, we get
The relationship between wavelength and frequency of the wave follows the equation:
where,
= frequency of the wave = ?
c = speed of light = 
= wavelength of the wave = 
The frequency of the light emitted by a hydrogen atom during a transition of its electron from the n = 4 to the n = 1 principal energy level is .
