CaCO3(s)= CO32-(aq)+ Ca2+(aq)does not result in any precipitates forming. 指令 Enter an equation of an ionic chemical equation and press the Balance button. The balanced equation will be calculated along with the solubility states, complete ionic equation, net ionic equation, spectator ions...
ReactantsProducts Ca11✔️ N22✔️ O99✔️ K22✔️ C11✔️ Step 3: Verify that the equation is balanced Since there are an equal number of atoms of each element on both sides, the equation is balanced. Ca(NO3)2+ K2CO3=2K(NO3) + CaCO3 ...
The balanced net ionic equation includes only species that are involved in the reaction. It can be found by removing ions that occur on both the reactant and product side of the complete ionic equation. 2CaCO3(s) + 2H+(aq) = Ca2+(aq) + 2HCO3-(aq) + Ca2+(aq) ...
Nais not balanced. Add1molecule ofNaNO3to the reactant (left-hand) side to balance Sodium: 2NaNO3+ CaCO3= Na2CO3+ Ca(NO3)2 ReactantsProducts Na22✔️ N22✔️ O99✔️ Ca11✔️ C11✔️ Step 3: Verify that the equation is balanced ...
K2CO3 + Ca(OH)2 = K(OH) + CaCO3 is a Double Displacement (Metathesis) reaction where one mole of aqueous Potassium Carbonate [K2CO3] and one mole of solid Calcium Hydroxide [Ca(OH)2] react to form two moles of aqueous Potassium Hydroxide [K(OH)] and one mole of sol...

不需要复合状态[如(s)(aq)或(g)]。 你可以用小括号()或括号[ ]。 例子 NaCl + KC2H3O2 = KCl + NaC2H3O2 CuSO4 + KI = CuI + KSO4 Ca + HF = CaF2 + H2 Mg + Fe(NO3)3 = Fe + Mg(NO3)2 CuCl2 + H2S = CuS + HCl
Na2CO3 + CaBr2 = CaCO3 + NaBr is a Double Displacement (Metathesis) reaction where one mole of aqueous Sodium Carbonate [Na2CO3] and one mole of aqueous Calcium Bromide [CaBr2] react to form one mole of solid Calcium Carbonate [CaCO3] and two moles of aqueous Sodium Bromide [NaBr] ...
CaCO3-SiO2 systems with Ca/Si molar ratios of 0.05, 0.1, 0.25, 0.5 and 1.0 were synthesized by aqueous sol-gel chemistry [21,22]. TEOS was used as a precursor of the starting silica gel, while acetic acid was applied as a main moderator of hydrolysis and condensation rates (regulation ...
