Answer:
Mass of P4O6=103.4
P4O10=133.48
Explanation:
Balanced reaction is:
8P +8 ⇒ +
Both reactant completely vanishes as equivalent of bot are equal.
Moles of P= =3.80
Moles of = =3.80
No. of moles of formed product are equal and is th of mole of any of reactant.
Thus weight of =×220 ≈103.41
weight of =×284 ≈133.48
I believe the answer is false. Hydrogen is in the S=1 energy level with helium which means that the only valence orbital hydrogen has is the 1s orbital. s orbitals only have 2 electrons in them meaning that in order for hydrogen to achieve a full valence energy level it would only need to gain 1 electron. Also if the question is asking how many electrons it would take for hydrogen atom to get an octet (eventhough it would never try to) it would still be false since it would need to fill the 2s and 2p orbitals after filling the 1s orbital. Hydrogen would need to gain 1 electron to fill the 1s orbital, 2 electrons to fill the 2s orbital, and 6 electrons to fill the 2p orbital which adds up to 9.
I hope this helps. Let me know if you have any further questions or if anything is unclear.
<span>No, the only places that free electrons can exist is in plasma, electrons unbind from their original atoms and bounce around. In the core of the sun, where nuclear fusion occurs, all electrons are unbound from their atoms.</span>
Answer:
True.
Explanation:
When copper and nitrogen combine they formed the bond which is called ionic bond.
Ionic bond:
It is the bond which is formed by the transfer of electron from one atom to the atom of another element.
Both bonded atoms have very large electronegativity difference. The atom with large electronegativity value accept the electron from other with smaller value of electronegativity.
For example:
The electronegativity of nitrogen is 3.04 and that of copper is 1.9. Nitrogen required three electrons to complete the octet while copper loses its one valance electron to complete the octet. Thus when both combine nitrogen atom accept three electrons from three atoms of copper and form ionic bond. The compound formed is called copper nitride.
