Answer:
A. 32.06 g/mol
Explanation:
The molar mass units are always g/mol
Answer:
I think it's nitrogen I'm not really sure..
Answer:
'*:*'
Explanation:
I know this looks weird, but
'= electron
*:* equals the nucleus, so 2 protons and 2 neutrons
and then '=electron
Answer:
CH 2 CH 3 CHCH = C6H5 + 5 Hydrogen Atoms

It is Cobalt(II)chloride dihydrate. The value of x is 2.
First, we have to determine the mass of H₂O that was evaporated upon heating which will be = 2.00g - 1.56 g
= 0.435 g
So,
CoCl₂ + x.H₂O → CoCl₂.xH₂O
Molecular mass of CoCl₂ = 129.839 g/mol
Molecular mass of H₂O = 18 g/mol
Weight of sample after heating = 1.565 g
Weight of H₂O evaporated = 0.435 g
Hence,

x ≈ 2
So, it is Cobalt(II)chloride dihydrate.
