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
Answer:
MARK AS BRAINLIEST
Explanation:
Boron trifluoride only has six valence electrons and is one of the relatively rare second period covalent molecules that disobeys the octet rule. There are three bonded groups and so no lone pairs. Six electrons implies three electron pairs and therefore a trigonal geometry.
Answer:
5 protons, 5 electrons, and 6 neutrons
