I'll balance it for you :D
HNO3 + P → <span>H3PO4 + NO
break it down first (to see how many of each atom on each side) so
H- 1 H-3
N-1 N-1
O-3 O-12
P-1 P-3
now u gotta make the numbers equal on both sides
make the first H 3 so it's balanced with the other one by putting a 3 in front of it in the equation like this:
</span>3HNO3 + P → H3PO4 + NO
<span>
that changes the WHOLE equation except the P because it's not attached (so now the N is also 3 and the O as well)
</span>H- 3 H-3
N-3 N-1
O-9 O-12
P-1 P-3
so now the N is imbalanced on the product side, so do the same thing to fix it
3HNO3 + P → H3PO4 + 3NO
the O next to the N is now also 3 sooo
H- 3 H-3
N-3 N-3
O-9 O-15
P-1 P-3
3HNO3 + 3P → H3PO4 + 3NO
H- 3 H-3
N-3 N-3
O-9 O-15
P-3 P-3
3HNO3 + 3P → H3PO4 + 3NO
i realized halfway through this that the O is still unbalanced SOMEHOW
I cant help unless there is an article..
Neon is the element that is classified as a noble gas at STP.
A because you can prove that with the graph you are given in the wuestion
