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
C. Biomass is the correct answer
The top number on elements in the periodic table is the atomic number, so when you look at the periodic table you can see that 42 is Mo (Molybdenum), and this is the only element with that atomic number.
