Which will diffuse faster AsH3 or HCN?
HCN will diffuse faster due to its lower molecular weight.
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 are the acids in the following equilibrium reaction cn- plus h2o hcn plus oh?
The acid in the reaction is hydrogen cyanide (HCN), which is formed when cyanide ion (CN-) reacts with water (H2O) to release hydroxide ion (OH-).
What is hcn in the periodic table?
HCN stands for hydrogen cyanide, which consists of hydrogen, carbon, and nitrogen atoms. Hydrogen is in the first column (group 1) of the periodic table, carbon is in the fourth column (group 14), and nitrogen is in the fifteenth column (group 15).
Why is cyanide poison?
Cyanides (HCN, KCN, NaCN) are lethal poisons, which block the respiration.
What is cyanide poison?
A compound containing the ion cyan as: HCN, KCN, NaCN.
What kind of poison is cyanide?
Cyanides (HCN, KCN, NaCN) are lethal poisons, which block the respiration.
What is Ka for HCN aq H aq CN aq?
ka=[H+][CN-]/[HCN]
Is HCN linear?
HCN is a linear molecule.
What is the shape of molecule of hcn?
HCN has a linear molecule.
Is hcn is a bAses?
HCN is hydrocyanic acid and is acidic (not basic).
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.
Is HCN or KCIO3 a salt?
HCN is an acid; KClO3 is a salt.
What is the nomenclature for HCN?
hydrogen cyanide
Is HCN an acid or base?
Yes and no. HCN is a salt, but it is also a weak acid.
What is the hybridization of the carbon atom in HCN?
The carbon atom in HCN is sp hybridized.
