Chapter 2: Q126CP (page 86)


From the following ions and their radii (in pm), choose a pair that gives the strongest ionic bonding and a pair that gives the weakest:

Mg2+72;K+138;Rb+152;Ba2+135;Cl-181;O2-140;l-220

Short Answer

Expert verified

The strongest bond is between Mg2+andO2The weakest bond is in betweenRb+andl-.

Step by step solution

01

Relation between ionic bond strength, charge product and radius of bond

The ionic bond strength is proportional to the charge of the product and inversely proportional to the bond radius.

02

Finding the strongest and weakest bond

The bondsMg2+andO2- can be considered as strongest due to their biggest product of the charges and lowest radius sum.

The bondsRb+andl- can be considered as weakest due to their smallest charge product and biggest radius sum.

Samples of illicit 鈥渟treet鈥� drugs often contain an inactive component, such as ascorbic acid (vitamin C). After obtaining a sample of cocaine, government chemists calculate the mass of vitamin C per gram of drug sample, and use it to track the drug鈥檚 distribution. For example, if different samples of cocaine obtained on the streets of New York, Los Angeles, and Paris all contain 0.6384 g of vitamin C per gram of sample, they very likely come from a common source. Do these street samples consist of a compound, element, or mixture? Explain.

When Rutherford's coworkers bombarded gold foil with particles, they obtained results that overturned the existing (Thomson) model of the atom. Explain.

Why was it necessary for separation techniques and methods of chemical analysis to be developed before the laws of definite composition and multiple proportions could be formulated?

How can iodine (Z = 53) have a higher atomic number yet a lower atomic mass than tellurium (Z = 52)?

Identify the mass law that each of the following observations demonstrates, and explain your reasoning:

(a) A sample of potassium chloride from Chile contains the same percent by mass of potassium as one from Poland.

(b) A flashbulb contains magnesium and oxygen before use and magnesium oxide afterward, but its mass does not change.

(c) Arsenic and oxygen form one compound that is 65.2 mass % arsenic and another that is 75.8 mass % arsenic.
