Hard glass which is used for making laboratory glass wares is a mixture of sodium borosilicate and aluminium borosilicate
Glass is decolorized during its manufacture by adding antimony oxide, manganese dioxide or arsenic oxide
Ordinary glass is represented chemically by Na2O . CaO . 6SiO2
Red color is imparted to glass by addition of arsenic oxide
DDT is manufactured by the condensation of chlorobenzene with chloral at 30°C in presence of oleum, which is a highly exothermic reaction
Chloral is obtained by the chlorination of ethyl alcohol
Insecticides acting on the insects through the respiratory system are called fumigants
Benzene hexachloride is not a contact insecticide
High electrical insulation properties
Sharp melting points
Low co-efficient of thermal expansion
Compressive strength much greater than their tensile strengths

Wine, rum & Vodka are prepared by the formulation of fruit juice, sugar beet & rye respectively
Protein catalysts are called enzymes
The rate of chemical reaction is independent of the concentration of reactants at high concentration of enzymes
Total sugar content in molasses is about 10%
