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试剂,溶液变红(...
Balance NaOH + H2O = Na(OH)2 + H2 Using Inspection The law of conservation of mass states that matter cannot be created or destroyed, which means there must be the same number atoms at the end of a chemical reaction as at the beginning. To be balanced, every element in NaOH + H2O ...
NaOH(aq)→ Na+(aq) + OH-(aq) 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...
2na+2h2o=2naoh+h2是氧化还原反应。氧化还原反应 （oxidation-reduction reaction）是化学反应前后，元素的氧化数有变化的一类反应。氧化还原反应的实质是电子的得失或共用电子对的偏移。 氧化还原反应是化学反应中的三大基本反应之一（另外两个为（路易斯）酸碱反应与自由基反应）。自然界中的燃烧，呼吸作用...
Sodium hydroxide or NaOH is an ionic compound that belongs to a class of compounds called bases. Also known as lye, it finds a wide variety of uses in chemistry labs, the chemical industry, and construction, among other applications. The following four e
NaOH+HCl=NaCl+H2O是中和反应。中和反应(neutralization reaction)酸和碱互相交换成分，生成盐和水的反应。即酸+碱→盐+水。中和反应的实质是：H+和OH¯结合生成水(H₂O)和盐。中和反应原理：溶于水后在水中被电离成自由移动的阴离子和阳离子。例如HCl被电离成氢离子(H)和氯离子(Cl)，...
