No, the balanced equation is
6Ca + 3O2 ---> 6CaO.
The product, calcium oxide, is CaO and not CaO2.
The equation is not balanced. It should read 2C3H6+9O2--> 6CO2+6H2O.
This equation is correct.
I think this is right... Cl2 + 2NaBr = 2NaCl + Br2
It is balanced.
2NaBr (s) + Cl2 (g) --------> 2NaCl (s) + Br2 (g)
When the equation kmno4 plus mgs k2s plus mgmno42 is balanced, the correct set of coefficients is 2111.
Sodium plus Halogen yields Sodium Halide
the balanced equation is Na2S2O3 plus H2O2 yields 2NaOH plus H2S2O3 plus O2.
3H2 + N2 yields 2NH3
6CO2 + 6H20 +energy yields C6H12O6 + 6O2. This is the equation for photosynthesis.
2PbO ---> 2Pb + O2
No. This equation is not balanced and does not even represent any reaction. The equation for the actual reaction between elemental zinc and chlorine is: Zn + Cl2 => ZnCl2.
MgBr2 + Cl2 --> MgCl2 + Br2
C + h2o = co + h2
4KClO3= 3KClO4+KCl
The equation is balanced, but it's not as simple as it can be. The correct equation is: Zn(s) + 2HCl(aq) → ZnCl2(aq) + H2(g)
Balanced :2 K + 2 H2O ----> 2 KOH + H2
PdCl2 + 2HNO3 --> Pd(NO3)2 + 2HCl
I think this is right... Cl2 + 2NaBr = 2NaCl + Br2
