Answer:
Density is mass over volume.
Explanation:
Oxygen-8×2=16, sulphur=16
1mole=6.023×10^23molecule=22.4l=32gram
32g=6.023×10^23molecule
1g=6.023×10^23÷32
13.5g=6.023×10^23÷32×13.5
=2.5×10^23 molecule
.°. there are 2.5×10^23 molecule in 13.5g of sulphur dioxide
The measure is the same. :)
Explanation:
This is feasible single displacement chemical reaction. In this reaction, Zinc displaces cadmium from the chlorate solution:
Zn + Cd(ClO₃)₂ → Zn(ClO₃)₂ + Cd
A single displacement reaction is a reaction in which one specie replaces another.
The main driving force in this kind of reaction is the position of the displacing species in the activity series.
In the series, metals that are higher up are more reactive and they will displace the lower ones from solution.
Cadmium is lower in the series and Zn is higher up.
Zn is more reactive than Cd and will displace it form the solution and it gives the expression:
Zn + Cd(ClO₃)₂ → Zn(ClO₃)₂ + Cd

I think it is an oxygen atom, I am not completely sure though.
