What else can I help you with?
When aqueous solutions of sodium cyanide and hydrochloric acid are mixed an aqueous solution of sodium chloride and hydrocyanic acid results Write the net ionic equation for the reaction?
The net ionic equation for the reaction is: CN^- + H^+ -> HCn
What is the net ionic equation for ammonia plus hydrocyanic acid?
NH4OH + HC2H3O2 ---> NH4C2H3O2 + H2ONH4+ + OH- + H+ + C2H3O2- ---> NH4+ + C2H3O2- + H2OOH- (aq) + H+ (aq)---> H2O (l)
What is the conjugate base of HCN?
The conjugate base of HCN is CN-. It is formed when HCN donates a proton (H+) and becomes negatively charged.
What is the conjugate acid of CN?
HCN - Hydrogen cyanide The conjugate acid of CN- is HCN. HCN stands for hydrogen cyanide. The conjugate acids are a combination of a strong acid and a low base.
What is Ka for H3BO3(aq) = H+(aq)+H2BO3 -(aq)?
Ka= [H+] [H2BO3-] / [h3BO3] (Apex)
What is Ka for HCN(aq) H plus (aq) plus CN and ndash(aq)?
HCN(aq) ==> H^+(aq) + CN^-(aq)Ka = [H+][CN-]/[HCN] and the value can be looked up in a book or on line.

At a certain temperature a 0.16 m solution of hcn has a pH of 4.29 what is the ka of hcn at this temperature?
A pH of 4.29 corresponds to a hydrogen ion concentration of 10-4.29, which equals 10-5 X 10+0.71, since 0.71 - 5 = -4.29. 10+0.71 = 5.1, to the justified number of significant digits. By definition, Ka = [H+]X[CN-]/[HCN], and in the absence of other sources of cyanide anions, [H+] = [CN-]. Within the number of significant digits given, [HCN] = 0.16, and Ka then = (5.1 X 10-5)2/0.16 = 1.6 X 10-8.
What is the net ionic equation for ammonia plus hydrocyanic acid?

What is Ka for H2CO3 aq H aq HCO3 aq?
Ka= [h+][HCO3-]/[H2CO3]
A dynamic equilibrium is reached when hydrogen cyanide acid is dissolved in water Which species is present in the highest concentration in this solution?
C2H3O2-(aq) H+(aq) H3O+(aq) OH-(aq) HCN(aq)Those are the choices that could be given, but the answer is HCN. It can't be H+ or OH- because the water is de-ionized and H3O+ is not possible.
What is Ka for H3BO3(aq) H (aq) H2BO3-(aq)?
