The chemical formula for Calcium Sulfate is CaSO4
The formula for iron is Fe. The formula for copper sulfate is CuSO4. The chemical equation for the reaction is Fe (s) + CuSO4 (aq) --------- Cu (s) + FeSO4(aq) The iron is a more active metal than copper therefore it replaces the copper in the copper sulfate solution.
Ca(OH)2 (aq)
Ca(NO3)2 + 2KI ----> CaI2 + 2KNO3
Ni+2 SO4-2 <--- These are the ions and their charges. The charges have to have a net charge of zero, so one +2 nickel ion cancels out one -2 sulfate ion. The final formula would then be NiSO4
NH3 (aq) + H2O (l) --> NH4+ (aq) + OH- (aq)
The formula for iron is Fe. The formula for copper sulfate is CuSO4. The chemical equation for the reaction is Fe (s) + CuSO4 (aq) --------- Cu (s) + FeSO4(aq) The iron is a more active metal than copper therefore it replaces the copper in the copper sulfate solution.
Ca(OH)2 (aq)
The chemical formula for iron sulfate is FeSO4. When it is dissolved in water, it forms aqueous iron sulfate, which is represented as FeSO4(aq).
Mn(s) + H2SO4(aq) ------> MnSO4(aq) + H2(g) [molecular] Mn(s) + 2H+(aq) -----> Mn2+(aq) + H2(g) [net ionic]
This reaction equation is usually written H2SO4 (aq) + Ca(OH)2 (aq) -> H2O + CaSO4 (aq) [or possibly (s), depending on the concentrations].
Ca(NO3)2 + 2KI ----> CaI2 + 2KNO3
Write the ionic and net ionic equations and it turns out there is no reaction.Ca^2+(aq) + 2OH^-(aq) + 2NH4^+(aq) + SO4^2-(aq) ==> Ca^2+(aq) + SO4^2-(aq) + 2NH4^+(aq) + 2OH^-(aq) ... ionic equation.NOTE: all species are soluble, therefore NO REACTION
Ca2+(aq)
The chemical formula for lime water is Ca(OH)2(aq) + CO2(g) --> CaCO3(s) + H2O(I). It is an insoluble suspension of calcium carbonate.
Ni+2 SO4-2 <--- These are the ions and their charges. The charges have to have a net charge of zero, so one +2 nickel ion cancels out one -2 sulfate ion. The final formula would then be NiSO4
This reaction is: Fe(s) + CuSO4(aq)----- --> FeSO4(aq) + Cu(s)
chemical formula is an abbreviation representing the molecules of an element or a compound . The number and kind of the atoms of elements can be understood from the chemical formula . The symbol and number of atoms of each element will be indicated in the chemical formula.
