Balance the reaction equation if the reactant is written in brackets?
Pb(NO₃)₂ —> PbO + NO₂ + O₂
I don't know how to compensate for this, because there is a bracket next to the reactant and there are also indices 🙈😅
Could someone explain the exclusion or the rule for it? 😄

Help :
Pb(NO3)2 = PbNO3NO3 = PbNNOOOOOO
Solution :
2 Pb(NO3)2 —> 2 PbO + 4 NO2 + O2
> Pb(NO3)2
This means that the “molecule” (better formula unit because no individual molecules are present) consists of a lead ion and two nitrate ions.
You could also write PbN2O6
It's not a math task, it's chemistry. There's no clasp.
You have 2 nitrations in the lead nitrate, you need to know that you don't want to find any rules.
Sometimes your equation is wrong, but you don't have to understand that chemically.
I can only compensate her if I understand how much I have from the starting materials? Otherwise, I can't go on.
You should know the structure of the fabrics. Lead(II) nitrate consists of lead and nitrations in a ratio of 1:2. Each nitration consists of an N and 3 O atoms and has a negative charge as a whole.
Recognition is then primary.
Approaching chemistry from the mathematical side has never been well, it is about substances and reactions that you must know.
Multiply. Like in math.
And where we (the chemists) are constantly trying to make it clear to students that chemistry is not maths with element symbols.
That's why in chemistry the number is according to the bracket…
