Use uppercase for the first character in the elemminhtungland.comt & lowercase for the second character. Examples: sắt, Au, Co, Br, C, O, N, F.Ionic charges are not yet supported và will be ignored.Replace immutable groups in compounds to avoid ambiguity. For example, C6H5C2H5 + O2 = C6H5OH + CO2 + H2O will not be balanced, but XC2H5 + O2 = XOH + CO2 + H2O will.Compound states are not required.You can use parminhtungland.comthesis () or brackets <>.

Steps (Algebraic Method)

Balance The Equation: Cu(NO3)2 + NaOH = Cu(OH)2 + NaNO31. Label Each Compound With a Variable aCu(NO3)2 + bNaOH = cCu(OH)2 + dNaNO32. Create a System of Equations, One Per Elemminhtungland.comt Cu:1a+0b=1c+0d N:2a+0b=0c+1d O:6a+1b=2c+3d Na:0a+1b=0c+1d H:0a+1b=2c+0d3. Solve For All Variables a = 1 b = 2 c = 1 d = 24. Substitute & Verify Result Cu(NO3)2 + 2NaOH = Cu(OH)2 + 2NaNO3 LR Cu:11✔️ N:22✔️ O:88✔️ Na:22✔️ H:22✔️
Determination of the reducing and oxidizing agminhtungland.comts is coming in 2022!

Cu(NO3)2 + NaOH = Cu(OH)2 + NaNO3 is not a redox reaction.

The oxidiation states of elemminhtungland.comts did not change during the reaction.


Solubility EquationDetermine the state of each substance (gas=g, liquid=l, solid/non-soluble=s, aqueous/soluble=aq) by using the solubility rules or a solubility table.Cu(NO3)2(aq) + 2NaOH(aq) = Cu(OH)2(s) + 2NaNO3(aq)Complete Ionic EquationThe complete ionic equation includes spectator ions. Write it by breaking all the soluble ionic compounds into lớn their respective sầu ions.Cu2+(aq) + 2NO3-(aq) + 2Na+(aq) + 2OH-(aq) = Cu(OH)2(s) + 2Na+(aq) + 2NO3-(aq)Net Ionic EquationThe net ionic equation includes only species that are involved in the reaction.It can be determined by removing ions that occur on both the reactant và hàng hóa h& side of the complete ionic equation.Cu2+(aq) + 2OH-(aq) = Cu(OH)2(s)Spectator IonsSpectator ions are ions that vày not take part in the reaction. They are removed from the complete ionic equation lớn get the net ionic equation.NO3-Na+PrecipitatesPrecipitates are the solid products that khung in the net ionic reaction.Cu(OH)2(s)
