Calculate [H+],[OH-],[H3PO4],[H2PO4-],[HPO42-],and [PO43-] for a 0.100 M solution of H3PO4.

Calculate [H+],[OH-],[H3PO4],[H2PO4-],[HPO42-],and [PO43-] for a 0.100 M solution of H3PO4. Consider the following reaction.2 HCl(aq) + Ba(OH)2(aq) BaCl2(aq) + 2 H2O(l) ΔH = -118 kJ Calculate the heat when 104.8 mL of 0.500 M HCl is mixed with 300.0 mL of 0.415 M Ba(OH)2.Assuming that the temperature of both solutions was initially 25.0°C 请教一个AP chemistry的问题a solution is prepared by mixing 90.0mL of 0.050 M HCl to 30.0mL of 8.00 M HNO3.water is then added until the final volume is 1.00mL.Calculate [H+] [OH-],and the pH of the solution calculate是什么意思 Al(OH)3+H+生成 Al(OH)3能电离出H+和OH-,H+和OH-会不会反应? -OH与OH—的区别比如说：H+可以与OH-而不是-OH结合 为什么呢? al(oh)4-与oh-和h+反应 一首英文歌歌词有put your hands up oh oh oh oh o h oh oh o h挺好听的 H++OH-=H2O的化学方程式 H+与Fe(OH)3反应方程式 OH与 Mg2+ H+哪个先反应 H+ +OH-=H2O 表示什么 HCO3-,H+生成什么 和OH- 呢 -OH 叫羟基 那 -H 叫什么 原子团OH中H的化合价 ALO2- 与H+或 OH-能否共存 H+和OH-反应生成什么
