For the molecular balance of the equation it would be: CuSO4 (aq) + Na2S (aq) = CuS (s) + Na2SO4 (aq). For the net ionic balance of the equation it would be: Cu2+ (aq) + S2(aq) = CuS (s).
NaS2 is an unbalanced equation. It would need to be Na2S to be a balanced equation (two sodium, one sulfide). Na2S is Sodium Sulfide.
These two compounds doesn't react.
The molecular equation for the combustion of methane gas (CH4) in the presence of oxygen (O2) is: CH4 + 2O2 -> CO2 + 2H2O.
The balanced molecular equation for FeCl3 + CoCl2 is: 2FeCl3 + 3CoCl2 → 2FeCl2 + 3CoCl3
Molecular weight and sedimentation constant are related through the Svedberg equation, which states that the sedimentation constant (S) is inversely proportional to the molecular weight of a molecule. This means that larger molecules with higher molecular weights will have lower sedimentation constants, while smaller molecules with lower molecular weights will have higher sedimentation constants.
NaS2 is an unbalanced equation. It would need to be Na2S to be a balanced equation (two sodium, one sulfide). Na2S is Sodium Sulfide.
The correct molecular equation of, calcium carbonate-CaCO3 nitric acid-HNO3
The molecular equation for lithium phosphate and sodium iodide is: 2Li3PO4 + 3NaI -> 6LiI + Na3PO4
CaCO3
Molecular equation: CuSO4 + Na2CO3 → CuCO3 + Na2SO4 Net ionic equation: Cu2+ + CO3^2- → CuCO3
The balanced molecular equation for the reaction between CaBr2 and NaCO3 is: CaBr2 + 2NaCO3 -> CaCO3 + 2NaBr.
Hydrochloric acid dissolves in water but does not react with it; there is no equation.
These two compounds doesn't react.
The molecular equation for iron chloride and sodium hydroxide is: FeCl3 + 3NaOH -> Fe(OH)3 + 3NaCl.

In a molecular equation, all reactants and products are written as complete formulas, while in an ionic equation, only ions that participate in the reaction are written. Ionic equations focus on the dissociation of ionic compounds into their constituent ions, whereas molecular equations do not show this dissociation. Ionic equations provide a more accurate representation of the species involved in a reaction in solution compared to molecular equations.
