Answer:
A
Step-by-step explanation:
2 + 12 = 14 = 4 + 10
On the right side, there are
• 2•2 = 4 atoms of Nb
• 2•5 = 10 atoms of O
so among the reactants on the left, the reaction is balanced as
4 Nb + 5 O₂ → 2 Nb₂O₅
D is the answer because rise over run is going to left and plus 2 is on the y axis
6= w/8
is
w= -48
that should be if not sorry DX
