na+h2o离子方程式Na和H2O反应离子方程式是2NA + 2H2O =2NAOH + H2 钠水反应(sodium-water reaction)是指钠与水或蒸汽接触时伴随有升温、爆燃和发光等现象的剧烈化学反应。 钠会和水反应生成氢氧化钠和氢气,钠熔成银白色小球,在水面漂浮(密度比水小)四处漂荡(生成气体),不一会消失,往反应后的溶液中滴加酚酞...
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 or reaction ...
Na+(aq)+ OH-(aq)+ H(g)= H2O(l)+ Na(s) 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. Net Ionic Equation The balanced net ionic equation includes only species that are ...
