Rays having a wavelength greater than 400 nm (such as visible, infrared, radio waves, etc.) do not cause damage to the cell.
Ultraviolet (UV) radiation is electromagnetic radiation with a wavelength between 100 and 400 nm.
Ionizing radiation such as X and gamma rays also have a small wavelength (less than that of UV rays), and can penetrate the cell and cause damage to the cell.
The simplest ratio of elements in a molecule is called as Empirical Formula.
For Example,
Empirical formula of Benzene is CH
Empirical formula of Formaldehyde is CH₂O
Calculation of Empirical Formula:
Empirical formula can be calculated from Molecular formula by dividing the molecular formula with such number that all number of elements in molecular formula gets the lowest and simplest number.
Like Benzene Molecular formula is C₆H₆, when it is divided by 6 we get C₁H₁ or simply CH.
So, for acetic acid having molecular formula C₂H₄O₂ we can only divide it with 2 to have the simplest form, i.e.
C₂H₄O₂ ÷ 2 = C₁H₂O₁ or CH₂O
Result:
So the ratio of elements in acetic acid is
C : H : O
1 : 2 : 1
A direct relationship because a gas sample is directly proportional to its absolute temperature at constant pressure
Answer:
B. False
Explanation:
Solution -
A solution is referred to be a uniform mixture of various components , where the components are classified as solute and solvent .
The components can easily be segregated on the basics of the amount of the component , i.e. ,
- The component with higher concentration is referred to as the solvent.
And ,
- The component with lower concentration is referred to as the solute .
For example ,
In the solution of sugar and water , where 1 tablespoon of sugar is dissolved in 100 mL of water ,
- the concentration of sugar is less , and hence , is referred to as the solute ,
and ,
- the concentration of water is more , and hence, is referred to as the solvent.
They both have structures in common
