2014年9月13日 · For a reaction like HCl + H2O → Cl- + H3O+, why is this reaction heavily favoured to the right in water? I've heard explanations that the products on the right are stabilized by the polar water molecules (considering aqueous solution). I'm just struggling to fully understand this because the...

2017年2月26日 · The Wikipedia article about aqueous solutions claims that: An aqueous solution is a solution in which the solvent is water So basically, is writing $\\ce{HCl(aq)}$ equal to: $\\ce{HCl(l) + H2O(l)}$?

2016年6月28日 · $\begingroup$ Thanks so much for your answer. Yes, it was late I corrected the question format. What I still dont get is how the Hydrogen in HCl becomes an ion and vice versa for the Cl atom.

2018年5月1日 · I think that the initial step forms a tertiary amine, which then in the presence of the ketone and trace acid undergoes nucleophilic addition. But then, for the $\\ce{HCl/H2O}$ in the last step, whi...

2016年4月19日 · This is how my chemistry professor compared reaction of a weak and a strong acid with water: $$\ce{HCl + H2O -> H3O+ + Cl- + Heat}$$ In this case $\ce{H2O}$ breaks the bond between $\ce{H}$...

2008年11月16日 · The problem says: Enthalpy is always reported with respect to a reactant. Calculate the enthalpy change, DeltaH, for each reaction in terms of kJ/mol for one of the reactants. (i.e either HCL or NaOH). I had three reactions: 1. NaOH + HCL---->H20 +NaCl 2.NH4Cl +NaOH---->H20 +NH3 +NaCl 3...

2004年6月24日 · I don't think it makes a gas H2O + HCl -> H+(aq) + Cl-(aq) the hydrochloric acid just breaks up into ions, perhaps the gas really was steam, or possible resulting from another reaction inside the container, if you put a metal into hydrochloric acid, then it makes hydrogen gas and a salt, for example:

2017年1月18日 · Why does the hydrogen atom in $\\ce{HCl}$ (when dissociated in water) bond to the oxygen rather than staying with the chlorine atom. They ($\\ce{Cl}$ and $\\ce{O}$) have roughly the same electronegati...

2015年5月17日 · A molecule that has hydrogen bonding usually follows these two premises. 1.) There is a hydrogen atom involved 2.) Hydrogen must be bonded to a highly electronegative element which are nitrogen ($...

2019年1月5日 · Consider simply aqueous solutions of $\ce{H2S}$ and $\ce{HCl}$ . It is pretty much known that $\ce{HCl}$ is stronger than $\ce{H2S}$ in water.
