Question

Can somebody please please please help me with balancing equations? :( i'm so sad i can't figure it out.

Answer 1

What question?

Answer 2

lead (II) nitrate --> lead (II) oxide + nitrogen dioxide + oxygen

Answer 3

i just don't get it :/

Answer 4

First write out the empirical formula so you can balance it.

Answer 5

Pb(NO3)2 -> PbO + NO2 + O2

Answer 6

Okay, but I don't understand how to get it to the ratio.

Answer 7

notice there is an odd number of O on the right and always an even number of the left. Therefore, you must have 2 PbO

Answer 8

The ratios IS the balancing portion. You will deduce them when you put in the right amount of each.

Answer 9

Well, yes. But it's just confusing like how to balance them.

Answer 10

start with one element

Answer 11

then go element by element

Answer 12

Pb(NO3)2 -> 2 PbO + NO2 + O2
you need 2 Pb on the left to balance the 2 Pb on the right
2Pb(NO3)2 -> 2 PbO + NO2 + O2

Answer 13

now you need 4 N on the right to balance the 4 N on the left
2Pb(NO3)2 -> 2 PbO + 4NO2 + O2

Answer 14

there's 12 O on the left, and 12 on the right, so it's balanced

Answer 15

Oh okay thank you so much!
