For example, C6H5C2H5 + O2 = C6H5OH + CO2 + H2O will not be balanced, but XC2H5 + O2 = XOH + CO2 + H2O will. Compound states [like (s) (aq) or (g)] are not required. You can use parenthesis () or brackets []. How To Balance Equations Balance any equation...
To calculate the limiting reagent, enter an equation of a chemical reaction and press the Start button. The reactants and products, along with their coefficients will appear above. Enter any known value for each reactant. The limiting reagent will be ...
极稀溶液中，[OH−] ≈ [H+] >> [H2CO3] > [CO32−]，表明H2O⇌H+ + OH−占据支配地位。溶液的酸碱性质主要由起支配作用的质子转移反应控制。关键词：碳酸氢钠溶液；多重平衡；支配反应；反应产物含量图 中图分类号：G64；O6 Shift of the Dominant Proton Transfer Reaction from Autoprotolysis...

Reaction (7) has been confirmed experimentally in an earlier paper [1]. Decomposition voltage of the electrolysis is lowered by introducing CO2 into the catholyte to decrease the pH. Polarization characteristics and related phase diagrams of NaI-I2-H2O and Na2CO3-NaHCO3-H2O systems were examined...
碳酸钠和稀盐酸反应生成氯化钠、水和二氧化碳，化学方程式为，Na2CO3+2HCl═2NaCl+H2O+CO2↑；碳酸氢钠和盐酸反应生成氯化钠、水和二氧化碳，化学方程式为，NaHCO3+HCl═NaCl+H2O+CO2↑；故答案为：CaCO3+2HCl═CaCl2+H2O+CO2↑；Na2CO3+2HCl═2NaCl+H2O+CO2↑；NaHCO3+HCl═NaCl+H2O+CO2↑．...
The invention provides a NaCl-Na2SO4-H2O system and a process for producing NaHCO3, NH4Cl and NaCl from NH4HCO3, comprising the following steps of: (1) carrying out double decomposition reaction on materials of mirabilite bittern and ammonium hydrogen carbonate and then separating to obtain an ...
