 C2H8 + 4 O2 = 2 CO2 + 4 H2O

Hope this helps

Why not to use balancer?

Code: Select all

 2 H2S + O2 = 2 S + 2 H2O

The following redox equation takes place after platinum is placed in aqua regia solution (mixture of HCl and HNO3). Pt +Cl {-} + NO3 {-} ---> PtCl6{2-} + NO When it is balanced, what is the coefficient on the Cl{-}? You should not forget acidic environment: 3 Pt + 18 Cl{-} + 4 NO3...

Is it possible to balance this equation? BF3(g) + H2O(l) = HF(aq) + H2BO3(aq) If not, can you tell me what is wrong with the problem and why it cant be balance. Thank you Boric acid is wrong, it should be H3BO3: BF3(g) + H2O(l) = HF(aq) + H3BO3(aq) Then you can use balancer: http://www.webqc.org/ba...

Code: Select all

2 H3PO4 + 3 Ca&#40;OH&#41;2 = Ca3&#40;PO4&#41;2 + 6 H2O

Hope this helps

NH4 is a mistake. It should be NH3.
Then it is easy to balance:

Code: Select all

CS2 + 2 NH3 = H2S + NH4SCN

CuO + HCl = CuCl + H2O

if yes, help me to balance.
if no, why not?

It is not correct. Should be CuCl2 instead of CuCl:

Code: Select all

CuO + 2 HCl = CuCl2 + H2O

This one is impossible to balance.

You probably have Na2O2 instead of Na2O:

Code: Select all

2 Na2O2 + 2 H2O = 4 NaOH + O2

Hope this helps.

How can this be balanced when the left side doesn't have an NO2 compound?

There should be no O2 on the left:

Code: Select all

4 HNO3 + Cu = Cu&#40;NO3&#41;2 + 2 H2O + 2 NO2

Na2S2O5 + BaCl2

Thank you for your help.

Code: Select all

Na2S2O5 + BaCl2 = 2NaCl + BaS2O5

Hope this helps,

That looks very impressive!
Is it what you are work on?

You just forgot water:

Code: Select all

C7H6O3 + CH3&#40;OH&#41; = C6H4&#40;OH&#41;COOCH3 + H2O

... and now it is balanced!

1) 2 K3PO4(aq) + 3 MgCl2(aq) = 6 KCl(aq) + Mg3(PO4)2(s) 2) 2 Fe(NO3)3(aq) + 3 Na2CO3(aq) = Fe2(CO3)3(s) + 6 NaNO3 Hope this helps, ~peter

This one cannot be balanced.
You probably wanted to balance this one:
CH3CH2COOH + O2 = CO2 + H2O
