Assuming that the O2 gas acts like an ideal gas, we find
the following expression to be approximates of the behaviour of this gas:
<span>P V = n R T --->
1</span>
where,
P = pressure exerted by the gas
V = volume occupied
n = number of moles
R = universal gas constant
T = absolute temperature
Further, we assume that the number of moles and the
temperature are constant, hence reducing equation 1 into the form:
<span>P V = k --->
2</span>
where k is a constant. Therefore we can equate two
states:
P1 V1 = P2 V2
Since P1, V1 and V2 are given and we are to look for P2:
25 mL * 2 atm = 100 mL * P2
<span>P2 = 0.5 atm</span>
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.
