2Na+(aq) + 2OH-(aq) + Ni2+(aq) + 2NO3-(aq) = Ni(OH)2(s) + 2Na+(aq) + 2NO3-(aq) Spectator Ions Spectator ions are ions that do not take part in the reaction. They are removed from the complete ionic equation to get the net ionic equation. Na+ NO3- ...
Answer to: Write the balanced molecular equation, complete ionic equation, and net ionic equation for the following reaction. Ni(NO3)2(aq) +...
To balance the equation Ni(NO3)2*6H2O + NaOH = Ni(OH)2 + Na(NO3) + H2O using the algebraic method step-by-step, you must have experience solving systems of linear equations. The most common methods are substitution/elimination and linear algebra, but any sim...
NaOH(aq) + CO2(g) arrow Na2CO3(aq) + H2O(l) Given 2 grams of Cu(NO3)2 and excess NaOH, calculate how much Cu(OH)2 can be produced? The molar mass of NaOH is 40g/mol, how many grams of NaOH are required to yield...
由于NaOH溶液的存在,Al被氧化生成NaAlO2而不是Al(OH)3,故电池反应的化学方程式为:Al+3NiO(OH)+NaOH+H2O=NaAlO2+3Ni(OH)2。(2)阴极:2NO3-+6H2O+10e-=N2↑+12OH-阳极:10OH--10e-=5H2O+ O2↑在阳极区生成的H+通过质子交换膜到达阴极区,所以,当电子过程中转移10 mol e-时,Δm左= mol×32 g·...
