yay its me again posting the answers for chem cos i got a super duber uber good phone XD
lets all play tap tap revenge :DDDDDDDDDDDD

so here's the chem ans:

1a) Chlorine Oxygen
mass compo(g) 14.2 3.2
NO. of moles 14.2/35.5 3.2/16
= 0.4 = 0.2
Simplest ratio 2:1

Empirical Formula: Cl2O

1b) NO. of moles of Cl2O= 0.6x 10^23/6.0x10^23
= 0.1 mol
Molecular mass of compound = 17.4/0.1
=174

1c) Mr of empirical formula, Cl2O= 2(35.5)+16 =87
n= 174/87 = 2
molecular formula: Cl4O2

2a) Iodine Oxygen
mass compo(g) 50.8 16.8
No. of moles 50.8/127=0.4 16.8/16=1.05
Simplest ratio 1 : 2.6
1 : 3

Empirical Formula: IO3

2b) Molar mass of compound = 33.4/0.1 = 334g/mol

2c) Mr of IO3 = 127=3(16) = 175
n= 334/175 =2
Molecular formula = I2O6

3a) No of moles of P4 molecules = 6.2/124 = 0.05 mol
b) No of moles of O2 molecules = 4.8/32 =0.15 mol
c) Simplest ratio of P4 : O2 = 0.05: 0.15
= 1 : 3
d) Value of x=4
Value of y = 2x3=6

kays tats all :D jiayous for MYE everyone ( im using up my time to study geog to do this instead -.- if my geog dont do well im gonna chase after theresa XD)
