No, the balanced equation is
6Ca + 3O2 ---> 6CaO.
The product, calcium oxide, is CaO and not CaO2.
I think this is right... Cl2 + 2NaBr = 2NaCl + Br2
PbO ---> Pb + O2 Balanced 2Pbo ---> 2Pb + O2
The balanced equation for the reaction between HNO3 and NaHCO3 is: 2 HNO3 + NaHCO3 → NaNO3 + H2O + CO2
When the equation kmno4 plus mgs k2s plus mgmno42 is balanced, the correct set of coefficients is 2111.
The reaction is: C3H8 + 5 O2 -> 3 CO2 + 4 H2O
The balanced equation for this reaction is: 3H2 + N2 -> 2NH3
the balanced equation is Na2S2O3 plus H2O2 yields 2NaOH plus H2S2O3 plus O2.
NO!!!! There are two fluorines (F2), but only one fluorine in ' NaF '. You have 'lost' a fluorine. Remember the Law of Conservation of Mass. In chemical eq'ns you cannot 'magic' something up out of nowhere, or just lose it. It has to be balanced. Mass has to preserved on both sides of the reaction eq'n. So to balance the eq;n. we need two atom of sodium . Hence 2Na(s) + F2(g) = 2NaF(s) =[ Na-F + Na-F ]. NB Sodium exists as separate atoms hence ' Na + Na = 2Na'. However, fluorine is a diatomic molecule and exists as ' F-F- = 'F2'.
The balanced equation is: 2MgBr2 + Cl2 → 2MgCl2 + Br2
The balanced equation for this reaction is: 2 KClO3 -> KClO4 + KCl
6CO2 + 6H20 +energy yields C6H12O6 + 6O2. This is the equation for photosynthesis.
Balanced :2 K + 2 H2O ----> 2 KOH + H2
The balanced chemical equation for the reaction is: PCl3 + 3H2O → H3PO3 + 3HCl
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.
This equation is not balanced as given. To balance it, you need to change the coefficients of the reactants and products. The balanced equation is 4Al + 3O2 -> 2Al2O3.
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)
2Na + 2Fe(NO3)3 -> 6NaNO3 + 2Fe
