1.How is cement made?
3. How is soap prepared?
Answers
1) Limestone (containing the mineral calcite),
clay, and gypsum make up most of it. ... The
clinker is ground to a fine powder in a cement
mill and mixed with gypsum to create cement.
The powdered cement is then mixed with water
and aggregates to form concrete that is used in
construction.
2) Soaps are sodium or potassium salts of long
chain fatty acids. When triglycerides in fat/
oil react with aqueous NaOH or KOH, they are
converted into soap and glycerol. This is called
alkaline hydrolysis of esters. Since this reaction
leads to the formation of soap, it is called the
Saponification process.

Answer:
1. Cement manufacturing is a complex process that begins with mining and then grinding raw materials that include limestone and clay, to a fine powder, called raw meal, which is then heated to a sintering temperature.
2. Soap is a combination of animal fat or plant oil and caustic soda.
Soap is fragrant because of musk provided by a musk deer.
