V = 3 x 1 x 1.5 = 4.5 cm^3
m = d x V
= 19.32 x 4.5
= 86.94g
Answer:
CH4+ 2Cl2→CH2Cl2+ 2HCl
Explanation:
mass is 132.8`125
as methane and dichlormethane has the same molar ration 1 to 1
mol of ch4 is 1.5625
so 1.5625 times mr of ch2cl2 is 132.8125
From the negative side of the molecule.:)
Maybe it’s c ??? I’m not too sure sorry
Answer:
a. There are only 5 electrons in 2p. 2p should be filled with 6 electrons prior to 3s and 3p
b. There are 8 electrons in 2p. 2p should be filled only with 6 electrons (not 8)
Explanation:
The typical electron configuration: 1s2 2s2 2p6 3s2 3p6
a. There are only 5 electrons in 2p
=> should be 1s2 2s2 2p6 3s2 3p2
b. There are 8 electrons in 2p
=> should be 1s2 2s2 2p6 3s2 3p1
