Interpretation Introduction

Interpretation:

The number of each type of atom present in the given chemical formulas is to be determined.

Concept Introduction:

A compound is represented by a chemical formula, which gives the information about the elements present in that compound and the relative number of atoms contained in that compound.

In a compound, the atoms are combined in a fixed proportion, and to represent those proportions, chemical formula is used.

Answer to Problem 4.1YT

Solution:

a) 1 carbon atom and 4 chlorine atoms.

b) 2 aluminum, 3 sulfur, and 12 oxygen atoms.

Explanation of Solution

a) CCl4

The subscript indicates the number of each type of atom. Carbon atom is denoted by “C” and chlorine atom is denoted by “Cl”.

Therefore, CCl4 contains the following atoms:

1 C and 4 Cl.

b) Al2(SO4)3

When a group of atoms is shown within the parentheses and with the subscript outside the parentheses, then that subscript is used for the entire group of atoms. Therefore, Al2(SO4)3 contains the following atoms:

2 aluminum, 3 sulfur, and 12 oxygen atoms.

Aluminum is denoted by “Al”, sulfur is denoted by “S”, and oxygen is denoted by “O”.

2. Platinum and other group 10 metals often act as solid phase hydrogenation catalysts for unsaturated hydrocarbons such as propylene, CH3CHCH2. In order for the reaction to be catalyzed the propylene molecules must first adsorb onto the surface. In order to completely cover the surface of a piece of platinum that has an area of 1.50 cm² with propylene, a total of 3.45 x 10¹7 molecules are needed. Determine the mass of the propylene molecules that have been absorbed onto the platinum surface.
Chem 141, Dr. Haefner 2. (a) Many main group oxides form acidic solutions when added to water. For example solid tetraphosphorous decaoxide reacts with water to produce phosphoric acid. Write a balanced chemical equation for this reaction. (b) Calcium phosphate reacts with silicon dioxide and carbon graphite at elevated temperatures to produce white phosphorous (P4) as a gas along with calcium silicate (Silcate ion is SiO3²-) and carbon monoxide. Write a balanced chemical equation for this reaction.
