balancing equations help
we started balancing equations, and i don't really get it. i mean, i get the math and all that stuff. but for like, if an equation has a polyatomic ion, do you break that down or do you keep its oxidation number?
for example.
1. calcium oxide + water --> calcium hydroxide
2. sodium hydroxide + carbon dioxide --> sodium carbomate + water
can you give me what the balanced equation would be? i can probably go from there.
thanks.

Maybe give some free advice about: School?
1. CaO + H2O --> Ca(OH)2
2. 2NaOH + CO2 --> Na2CO3 + H2O
Those answers are right.
But NO3 would only be treated as one single unit as long as it sticks together and is the same on both sides. for example, it couldnt be NO3 and NO4.

you treat polyatomic ions exactly the same as you would a single ion like Na-. For example, you would treat NO3 as a single unit.
1. CaO + H2O --> Ca(OH)2
2. 2NaOH + CO2 --> Na2CO3 + H2O

well is it just words??we were given numbers and letters??
oxide and nate mean dif numbers..sorry thats probaly not much help..
