Phosphine is not very soluble in water compared to nonpolar substances. If you were to write a balanced equation for the reaction of PH3 with water, it would be an equilibrium reaction.
Sulfuric acid can be mixed with water but doesn't react.
The balanced equation for the reaction involved is as follows: C10H12O2 + Br2 + H2O ---> C10H13O3Br + HBr. Some C10H12O2Br2 will form as well.
The actual formula is KClO3 (with a lowercase L) Balanced equation: 2KClO3 --> 2KCl + 3O2
2h2 + o2 2h2o
C2h6+7o=2co2+3h2o
The reaction is: (CH3CO)2O + H2O = 2 CH3COOH
2 H2 + O2 = 2 H2O
The balanced reaction for the reaction of uranium fluoride, water and hydrogen gas is UF6 + 2 H2O + H2 = UO2 + 6 HF. The final products are uranium oxide and fluoric acid.
Na2O + CO2 -> Na2CO3 Balanced as is and I would call this a synthesis reaction.
To determine the stoichiometry of a reaction, you must first write out a balanced equation describing the reaction and then use the coefficients of this statement to represent molar ratios.
The chemical reaction is:HBr + NaOH = NaBr + H2O
I am not sure that this reaction is possible; iron(III) bromide and iron(III) carbonate are not stable in water.
