Explanation:
Element Atomic number Electronic configuration Hydrogen 1 1 Helium 2 2 Lithium 3 2,1 Beryllium 4 2,2 Boron 5 2,3 Carbon 6 2,4 Nitrogen 7 2,5 Oxygen 8 2,6 Fluorine 9 2,7 Neon 10 2,8
The elements of these groups are called representative elements.
The reaction is
2H₂(g) + O₂(g) ---> 2H₂O
Thus as per balanced equation two moles of hydrogen will react with one moles of oxygen.
There is a directly relation between moles and volume. [One mole of each gas occupies 22.4 L of volume at STP]
Thus we can say that two unit volume of hydrogen will react with one unit volume of oxygen
Now as we have started with equal units of volume of both oxygen and hydrogen, half of oxygen will be consumed against complete volume of hydrogen
so the gas which will remain in excess is oxygen
Answer:
Hey, I'll help but I don't know what your options are.
Explanation:
Answer:
Explanation:
According to octet rule there should be 8 electrons in the atom's subshell/valence shell. Giving it the same electronic configuration as a noble gas.
among the options:
c) option is correct, as 5 bonds to carbon is violating the octet Rule, 5 bonds means 10 electrons exceeding the noble gas configuration and violets the octet rule.
All the other options are are incorrect, they are following
octet rule. Three bonds of carbon is possible in the case of carbocation.
