There is 18.066* 10^23 molecules of carbon in 3.50 moles of carbon dioxide.
Answer:
Explanation:
To show the sequence of electrons filling sublevels in an atom, the Aufbau's principle is one of the tenets that must be satisfied to write a proper notation.
- Aufbau's principle states that "the sublevels with lower energies are filled up before those with higher energies".
- Note that based on this principle, we are not inferring that sublevels are filled in numerical order.
- The patter of filling is shown below:
1s 2s 2p 3s 3p 4s 3d 4p 5s 4d 5p 6s 4f 5d 6p 7s 5f e.t.c
3Mg + 2H3(PO4) —> Mg3(PO4)2 + 3H2
