1)
Lets take 100g of this compound.
It contains
50.05 g S and 49.95 g O.
2)
M(S) = 32.06 g/mol
M(O) = 16.00 g/mol
50.05 g S*1mol S/32.06 g S= 1.56 mol S
49.95 g O*1mol O/16.00 g O =3.12 mol O
3) S:O =
=1.56 mol S : 3.12 mol O = (1.56 mol /1.56 mol ) : (3.12 mol /1.56 mol) =1:2
(mol S):(mol O)=1 : 2
SO2
The first part is C a substitution and the second part is A i believe, please check with others first
Answer:
0.81mole
Explanation:
Given:
Volume of carbon monoxide = 18dm³
Unknown
Number of moles of carbon monoxide = ?
Solution:
To solve this problem;
1 mole of any gas at rtp occupies a volume of 22.4dm³
So;
x mole of carbon monoxide will occupy a volume of 18dm³ at rtp
22.4x = 18
x = = 0.81mole
Answer:Lithium is obtained by passing an electric charge through lithium chloride and from the mineral called spodumene.
Explanation:
I looked it up for you
B. Increasing the effective nuclear charge on an ion results in energy levels that are closer together.
