Question
Chapter 2, Problem 2.23QP
(a)
Interpretation Introduction
Interpretation:
Two metals less dense than water has to be found out.
Concept introduction:
- Periodic table is the table that shows the elements which are represented by various symbols, their
atomic number ,average atomic mass … and elements with similar chemical properties are grouped together. - Atomic number of the element is equal the number of protons in the nucleus of an atom, which is the characteristic of a chemical element and determines the place of corresponding element in the periodic table.
- Weight of the substance per its unit volume will give its density. And the unit of density is g/mm or
- Density of water is the weight of water per its unit volume. And its density is 1
- A metal is good conductor of heat and electricity. In periodic table most of the elements are metals.
- Non-metals are poor heat and electricity conductor compared with metals. In the periodic table, 17 elements are classified as non-metals.

20. The Brusselator. This hypothetical system was first proposed by a group work-
ing in Brussels [see Prigogine and Lefever (1968)] in connection with spatially
nonuniform chemical patterns. Because certain steps involve trimolecular reac
tions, it is not a model of any real chemical system but rather a prototype that
has been studied extensively. The reaction steps are
A-X.
B+X-Y+D.
2X+ Y-3X,
X-E.
305
It is assumed that concentrations of A, B, D, and E are kept artificially con
stant so that only X and Y vary with time.
(a) Show that if all rate constants are chosen appropriately, the equations de
scribing a Brusselator are:
