Explanation:
Since, the atomic number of nitrogen is 7 and its electronic distribution is 2, 5. So, in order to attain stability it needs to gain 3 electrons.
Hence, when it chemically combines another nitrogen atom then as both the atoms are non-metals. So, sharing of electrons will take place.
Also, there is no difference in electronegativity of two nitrogen atoms. Hence, compound formed 
is non-polar covalent in nature.
Sodium chloride because it contains the most reactive metal(sodium) and most reactive non-metal(chlorine).
Answer:
MgCl2-> Mg+Cl
mass 5.00g Mass=1.263g
RFM Mg=24+35.5 ×2= 95 RFM= 24
moles= 5.00÷ 95= 0.0526 Moles=0.0526
Explanation:
mas of Mg= 1.263 grams
Answer:
5.00×10-19 J
Explanation:
E = hv
but v = c ÷ wavelength
E = (6.626×10-34) × ((3×10^8)÷(398×10-9))
= 4.9945×10-19
≈5.00×10-19
Hope this helps
Explanation:
Competition stems from the fact that resources are limited. There are simply not enough of some resources for all individuals to have equal access and supply. Competition can occur between organisms of the same species, or between members of different species.
