Interpretation: The reason for name of polyatomic ion to be different from name of a binary compound needs to be explained.
Concept Introduction :
The term poly is used for more than two, polyatomic ion contains more than one atom.
Binary compounds are the common chemical compounds, where they are made by the two distinct elements. There are three types of binary compounds are present as ionic compounds, covalent compounds, binary acids. There are ionic, covalent, and metallic bonds are present between the binary compounds.
Answer to Problem 2RQ
For the binary compounds, the cation is written first according to its oxidation state and the anion is placed second with the suffix −ide.
In polyatomic ion, the atoms are covalently bonded and the cation position is first than anions. The charge of the polyatomic ion is unbalanced.
Explanation of Solution
Polyatomic ions are bonded with a covalent bond. The atoms bonded in a polyatomic ion having an unbalanced charge. Compounds formed from such a combination of ions are polyatomic ionic compounds.
In binary compounds, two different elements are combined and form binary compounds.
There are ionic, covalent, and metallic bonds are present between the binary compounds. Binary compound the naming is based on the oxidation state and suffix for the anions. In polyatomic ion, the position of the cation is just before the anion. Covalent bonding is present in polyatomic ion.

- need help not sure what am doing wrong step by step please answer is 971A During the lecture, we calculated the Debye length at physiological salt concentrations and temperature, i.e. at an ionic strength of 150 mM (i.e. 0.150 mol/l) and a temperature of T=310 K. We predicted that electrostatic interactions are effectively screened beyond distances of 8.1 Å in solutions with a physiological salt concentration. What is the Debye length in a sample of distilled water with an ionic strength of 10.0 µM (i.e. 1.00 * 10-5 mol/l)? Assume room temperature, i.e. T= 298 K, and provide your answer as a numerical expression with 3 significant figures in Å (1 Å = 10-10 m).arrow_forwardInfluence of salt concentrations on electrostatic interactions 2 Answer is 2.17A why not sure step by step please What is the Debye length in a concentrated salt solution with an ionic strength of 2.00 mol/l?
