Answer:
The order in which the orbitals is filled is 1s-2s-2p-3s-3p-4s-3d-4p-5s-4d-5p-6s-4f-5d-6p-7s-5f-6d-7p
Explanation:
S orbitals each hold two electrons, p orbitals hold 6, d orbitals hold 10, and f orbitals hold 14. 1s has the least energy and 7 p has the greatest energy, so the order in which they are filled is listed above.
HCl is NOT an organic molecule.
It contains <em>no carbon</em>.
All the other compounds are organic because they contain both C and H.
Answer:
since that's the closest option we have
10.6atm
Explanation:
Since volume is constant
P1/T1 = P2/T1
P1 =8.5atm
T1 = 59.2°C = 332.2k
T2 = 140°C = 413k
P2 = ?
8.5/332.2 = P2/413
0.026 = P2/413
P2 = 0.026 x 413
P2 = 10.74atm
Answer: Silicon
Explanation: Silicon has less electrons than phosphorus.
Answer:
See answer below
Explanation:
This is pretty easy to solve. First you need to understand that an ionic compound is usually formed between a metal and a non metal. This usually happens between elements from group 1 through group 10 or 11 of the periodic table. A covalent compound is always given in non metal elements from the periodic table, and it's usually the elements from group 13 through group 17.
Some compounds there are missing some atoms, but I manage to find this question and saw the atoms missing, so, in my answer you will see the corrected compound. so don't be surprised.
According to what I state above, then the covalent compounds are:
C₆H₅N
PCl₃
C₂H₄O
NH₃
N₂
SO₄²⁻
The ionic compounds are:
CaO
CdBr₂
WO₂
Na₂O
CsF
Hope this helps
