Pb(C2H3O2) + K2CrO4 > PbCrO4
2Fe(SO4)3 + 6KOH ---> 2Fe(OH)3 + 3K2(SO4) iron 3 is +3, sulfate is -2, potasium is +1, and hydroxide is -1
Potassium hydride reacts with water to produce potassium hydroxide and hydrogen gas. KH + H2O --> KOH + H2
soap >;)
4NH3 + 5O2 -----> 4NO + 6HOH
Magnesium oxide, or MgO, is an ionic compound: the result of a metal reacting with a non-metal.
2K + H2O ----> K2O + H2
total ionic equation (also known as the complete ionic equation) for the reaction of potassium carbonate with hydrochloric acid
2KOH + H2SO4 -> 2H2O + K2SO4
k2o+ h2co3 --> h2o + k2co3
Ca(OH)2 + H2SO4 = CaSO4 + 2 H2O
I assume a double displacement reaction. At least ideally. 2KI + CaS -> K2S + CaI2
toluene is benzene with CH3 reacting this with KMnO4 in acidic solution will produce a benzene with a carboxylic acid (CH3 will be oxidized)
molecular equation: CuSO4 (aq)+Fe (s) --> Cu(s) + FeSO4(aq) net ionic equation: Cu2+(aq) + Fe2+ (s) --> Cu2+(s) + Fe2+(aq) spectator ion: Sulfate Ion (SO42-)
Potassium is too reactive to mix with acid
by coating it with oil
No, reacting zinc with hydrogen chloride will yield zinc chloride and hydrogen gas. Potassium chloride can be prepared by reacting potassium with hydrogen chloride or (more safely) potassium hydroxide with hydrogen chloride.
