Balancing Equations

[Seanm23]

Instructions: Balance the equation with the lowest whole-number ratio.

1. ___C₁₂H₁₈N₃O + ___O₂ = ___CO₂ + ___H₂O + ___N₂O₅

2. ___UO₂(NO₃)₂ = ___UO₃ + ___NO₂ + ___O₂


what are the numbers that I would fill in?

[ChenBeier]

First N₂O₅ will not be created in this case. It will only N₂. N₂O₅ is very unstable.
But I show the calculation with N₂O₅
How to start
Use first 1

1 C₁₂H₁₈N₃O + ___O₂ = ___CO₂ + ___H₂O + ___N₂O₅
then look how much CO₂ you can make 12. Water will be 9. N₂O₅ 1.5

C₁₂H₁₈N₃O + ___O₂ = 12 CO₂ + 9 H₂O + 1.5 N₂O₅

Then calculate the oxygen 19.75

C₁₂H₁₈N₃O + 19.75 O₂ = 12 CO₂ + 9H₂O + 1.5 N₂O₅
Times 4

4 C₁₂H₁₈N₃O + 79 O₂ = 48 CO₂ + 36 H₂O + 6 N₂O₅
Try the other one by yourself.

Awesome, thanks for the help! Appreciate it!

[ChenBeier]

Tell me the result of the second equation.

[Seanm23]

2. __2_UO₂(NO₃)₂ = _2__UO₃ + _4__NO₂ + _1__O₂

This should be correct, I believe?

[ChenBeier]

Yes correct
