Answer:
Na: 1s2 2s2 2p6 3s1
Na+: 1s2 2s2 2p6
Na+ electronic configuration resemble that of Neon( 1s2 2s2 2p6)
In general, the electronic configuration of alkali metals ions resemble that of the group zero (noble gas)
Explanation:
The Sun's gravatitional pull drags the earth around the earth as well with the other planets surrounding the sun
As per the problem 2 moles of propane are produced when 7 moles of carbon are supplied
so if we supply 1 mole of carbon the moles of propane obtained = 2 /7
if we supply 1.4 moles of carbon the moles of propane obtained = 2 X 1.4 /7 = 0.4 moles of propane
Hence answer is propane we can produce using this reaction = 0.4 moles from 1.4 moles of carbon
