Answer:
1
Explanation:
single displacement replaces one element with another and it's product is a pure element.
Explanation:
the intensity of a He-Ne laser (633 nm ,5 mW) transmitted by different Gase samples is observed to change in correlation with the Nd-yttrium-aluminium-garnet laser pulse (532 nm, 7.8ns ,3mJ) which excites them
Valence electrons in NH2Cl:
=1(5)*2(1)*1(7)
=14
So there are 14 valence electrons in NH2Cl
As each stick represents an valence electron pair.
And there are 14 valence electrons, so there can be 7 valence electron pairs.
And for 7 valence electron pairs, 7 sticks needed.
