Overlap of two p atomic orbital produces oxygen gas ,o2 because it has two unpaired electron and explains paramagnetism.
O2 molecules have two unpaired electrons Materials in which all the electrons are paired are diamagnetic. It repel a magnetic field.Para magnetic and diamagnetic materials do not act as permanent magnets. Molecular orbital theory provides an explanation of chemical bond that explains paramagnetism of the oxygen molecule. It also explains the bonding in a other molecule. O2 molecule has two unpaired electron. Electrons creates magnetic field as it goes to the ground state and also spin.MO theory describes the distribution of electrons in molecules same as the distribution of electrons in atoms described using atomic orbital.

The General Equation of Alkane is as follow,
CnH₂n₊₂ ------- (1)
As m/z = 380
So,
CnH₂n₊₂ = 380
Or,
12n+ 1₂n₊₂ = 380
12n+ ₂n ₊ ₂ = 380
14n ₊ ₂ = 380
14n = 380 - 2
14n = 378
n = 378 / 14
n = 27
Now, putting value of n in eq. 1
C₂₇H₍₂₇ₓ₂₎₊₂
C₂₇H₅₆
Result:
n = C = 27
y = H = 56
Answer: 0.0345 sec
Explanation:
Rate law says that rate of a reaction is directly proportional to the concentration of the reactants each raised to a stoichiometric coefficient determined experimentally called as order.
![Rate=k[H_3PO_4]^2](https://tex.z-dn.net/?f=Rate%3Dk%5BH_3PO_4%5D%5E2)
k= rate constant = 
Expression for rate law for first order kinetics is given by:
where,
k = rate constant
t = age of sample
a = let initial amount of the reactant
a - x = amount left after decay process
for completion of 20 % of reaction
The time taken for the concentration of 
to decrease to 20% to its natural value is 0.0345 sec
Answer:
pH of 7.86, then the [OH-] is equal to 10^(14-7.86) = 10^6.14 M
Explanation:
