Answer:
The number of moles of Fe in 1.17*10^22 atoms Fe is 0.0194 moles
Explanation:
Step 1: Data given
Number of atoms of Fe = 1.17 * 10^22 atoms
Number of Avogadro = 6.022 *10^23
Step 2: Calculate number of moles Fe
Moles Fe = atoms Fe / number of Avogadro
Moles Fe = 1.17*10^22 atoms / 6.022*10^23 / moles
Moles Fe = 0.0194 moles
The number of moles of Fe in 1.17*10^22 atoms Fe is 0.0194 moles
Answer:
Indirect. I don't think it's cycling and it's not direct or constant
Answer:
P1V1/T1 = P2V2/T2
Explanation:
- Hope that helped! Let me know if you need further explanation. Sorry I didn't give you exaxt one, it was kinda hard to read, but that is the correct answer I put above.
I believe a solution of Sn(NO3)2 can not be stored in an aluminium container because Aluminium is higher in the reactivity series compared to Tin (Sn). Therefore, Aluminium is more reactive than Tin and hence aluminium will displace Tin from its salt forming Aluminium nitrate and Tin metal. Thus storing Tin nitrate in an aluminium container will cause the "eating away' of the container.
