Interpretation:
Based on the location of carbon and silicon, the similarities between the properties of carbon and silicon are to be predicted.
Concept Introduction :
The periodic table is a columnar structure that organizes different elements into groups based on how they behave.The elements in the periodic table of today are ordered according to the periodic law.The elements are organized in the modern periodic table in increasing order of their
Answer to Problem 29A
Carbon and silicon are expected to have the same properties as they belong to the same group.
Explanation of Solution
Elements placed in the same group are expected to have similar chemical and physical properties. Carbon and silicon are placed in group 14.
Thus, carbon and silicon will exhibit similar chemical and physical properties.

- The acid-base indicator HX undergoes the following reaction in a dilute aqueous solution: HX (color 1) H+ + X- (color 2). The following absorbance data were obtained for a 0.00035 M solution of HX in 0.1 M NaOH and 0.1 M HCI. Measurements were made at wavelengths of 450 nm and 620 nm using a 1.0 cm glass cuvette. 450 620 A(460 nm) A(630 nm) 0.1 M NaOH 0.1 M HCI 0.065 0.435 0.895 0.150 In the 0.1M NaOH solution, the indicator will be almost 100% in the X- form, while in 0.1M HCI, the indicator will be nearly 100% protonated (HX). Calculate the acid dissociation constant for the indicator if a pH=5 buffer solution containing a very small amount of indicator exhibits an absorbance of 0.567 at 450 nm and 0.395 at 620 nm (measured in a 1 cm glass cuvette).arrow_forwardShow work...give the name of the given compound.
