Mass= number of mole *Molar mass
mass =2.92 mol*87.62 g/mol≈256 g
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.
Answer:
D
Explanation:
Breaking bonds absorbs (Requires) energy. Forming bonds releases it. It's kinda backwards but that's how it works. :)
Answer:Matter makes up everything you can see, including clothes, water, food, plants, and animals. It even makes up some things you cannot see, such as air or the smell of perfume. You can describe a type of matter by its MATERIAL PROPERTIES such as its colour or how hard it is.
