Chapter 2: Q15P (page 81)

Which of the following scenes illustrate(s) the fact that compounds of chlorine (green) and oxygen (red) exhibit the law of multiple proportions? Name the compounds.

Short Answer

Expert verified

Scene B exhibit the law of multiple proportions. Compounds formed are dichlorine monoxide and chlorine dioxide.

Step by step solution

01

Law of Multiple Proportions

According to the law of multiple proportions, when two elements combine to form more than one compound, the ratio of the masses of those compounds will always be in small whole numbers.

02

Explanation

Here in picture b, two compounds of Cl and O are formed as are dichlorine monoxide Cl2O and chlorine dioxide ClO2:

Compound I

Compound II

Mass of Cl

71

35.5

Mass of O

16

32

g of Cl/ g of O

4.43

1.10

Ratio of Mass of Cl in two compounds = RatioincompoundIRatioincompoundII=4.431.1=4

As the ratio is coming as whole number that means it is following law of multiple proportions.

Hydroxyapatite, Ca5(PO4)3(OH), is the main mineral component of dental enamel, dentin, and bone, and thus has many medical uses. Coating it on metallic implants (such as titanium alloys and stainless steels) helps the body accept the implant. In the form of powder and beads, it is used to fill bone voids, which encourages natural bone to grow into the void. Hydroxyapatite is prepared by adding aqueous phosphoric acid to a dilute slurry of calcium hydroxide. (a) Write a balanced equation for this preparation. (b) What mass of hydroxyapatite could form from 100 g of 85% phosphoric acid and 100. g of calcium hydroxide?
