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).
What are the intermolecular forces present in hydrogen cyanide?
The main IM force in HCN would be dipole-dipole and secondary would be dispersion.
In which of the following compounds are dipole-dipole attractions the most important intermolecular force ccl4 n2 ch3cl mgbr2 hcn or ch3co2h?
The compound where dipole-dipole attractions are the most important intermolecular force is CH3Cl (methyl chloride). This is because CH3Cl has a permanent dipole moment due to the difference in electronegativity between carbon and chlorine atoms, leading to strong dipole-dipole interactions.
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.
What is the chemical formula for hydrocyanic acid?
The chemical formula for hydrocyanic acid is HCN.
