Answer:
The new volume is 1.62 L
Explanation:
Boyle's law says:
"The volume occupied by a given gas mass at constant temperature is inversely proportional to the pressure." It is expressed mathematically as:
Pressure * Volume = constant
o P * V = k
Charles's law is a law that says that when the amount of gas and pressure are kept constant, the ratio between volume and temperature will always have the same value:
Gay-Lussac's law indicates that when there is a constant volume, as the temperature increases, the gas pressure increases. And when the temperature is decreased, the gas pressure decreases. So this law indicates that the quotient between pressure and temperature is constant.
Gay-Lussac's law can be expressed mathematically as follows:
Combined law equation is the combination of three gas laws called Boyle's, Charlie's and Gay-Lusac's law.
Having an initial state 1 and a final state 2 it is possible to say that:
Standard temperature and pressure (STP) indicate pressure conditions P = 1 atm and temperature T = 0 ° C = 273 ° K. Then:
- P1= 1 atm
- V1= 1.2 L
- T1= 273 °K
- P2= 0.80 atm
- V2= ?
- T2= 21°C= 294 °K
Replacing:
Solving:
V2= 1.62 L
<u><em>The new volume is 1.62 L</em></u>

Answer:
- COVELENT BOND:-The chemical bond formed by the sharing of an electron pair between two atoms so that both the atoms get their octet complete is called covalent bond
- SINGLE COVELENT BOND:-it is formed by sharing of one pair of electron between two atoms
- DOUBLE COVELENT BOND:-it is formed by sharing of two pair of electron between two atoms
- TRIPLE COVELENT BOND:- it us formed by sharing of three pair of electron beyween two atoms
2)Electron dot structures of carbon dioxide:-Oxygen atom contains 6 valence electrons which form 2 lone pairs. Since it is bonded to only one carbon atom, it must form a double bond. Carbon atom contains four valence electrons, resulting in zero lone pairs. Therefore, it is doubly bonded to each oxygen atom.
3))Sulfur has an atomic number is 16 with the
symbol as 'S'
- The electronic configuration of sulfur is said to be 2,8,6
- The valence electrons present in sulfur is 6.
- Sulfur forms an octet structure by connecting 8 sulfur atoms with each other by the formation of single covalent bonds.
- The sulfur molecule's chemical formula is S8.
- Sulfur is usually used in the manufacture of sulphuric acid.
