This is given by Avogagro number: 1 mol = 6.02*10^23 particles
Then you can do whichever to these two relations, because they are equivalent:
- 1mol / 6.02*10^23 representative particles, and
- 6.02*10^23 representative particle /1 mol
Only the second option of the question includes one of the valid conversion factors. Then, the conversion factor of the second option is the right answer
Answer:
2
b= they are grouped differently, but all the atoms are still there.
Heptane means seven carbon atoms and since the general formula is CnH2n+2, heptane will be C7H16
Reaction rates can be increased if the concentration of reactants is raised. An increase in concentration produces more collisions. The chances of an effective collision goes up with the increase in concentration. The exact relationship between reaction rate and concentration depends on the reaction "mechanism".
What is most widely accepted today is the giant-impact theory. It the Moon formed during a collision between the Earth and another small planet, about the There may indeed be several objects in orbit around Earth.
