Read the given passage and answer the questions. Suhana wanted her house to be white washed, She bought 10 kg of quicklime from the market and dissolved it in 30 L of water. On adding lime to water, she observed that the water started boiling even when it was not being heated. The common name for quick lime is:

In an industrial process, coke is heated with quicklime in an electric furnace and th cooled product is then treated with water to produce

Limestone is a naturally occuring form of calcium carbonate. It is used as building materials and also for manufacture of other building materials such as portland cement. It is used for the production of quickline and slaked lime which have wide applications in chemical, metallugical and construction industry. The pure CaCO_(3) , called precipitated calcium carbonate, is used extensively as filler, providing bulk to materials such as paint, plastics, printing links and rubber. it is also used in toothpastes, cosmetics and antacids. Quicklime and slaked lime are the cheapest and the most widely used bases for neutralising unwanted acids. Lime is used to neutralise acidic soils. An important application of quicklime is in air pollution control for the removal of SO_(2) in electric power plants. slaked lime is used in the manufature of other alkalis and bleacing powder, in sugar refinig, in tanning hide and in water softening. Quicklime is used in electric power plants with carbon to check pollution. What product of calcium is formed?
