A small amount of quick lime is taken in a beaker. Water is added slowly to the beaker. Which of the following observations will be noted?

(b) carbon dioxide

The water in the Ramesh's beaker will heat up in a shorter time. This is because the outermost zone of a flame is the hottest zone, while the yellow zone...

[Hint : Silica gel : Adsorption, Anhydrous CaCl2 : Absorption, as it forms Ca- Cl2.2H2O]

Most of the plants grow best when the pH of the soil is close to 7. If the soil is too acidic or too basic, the plants grow badly or...

(A) (i) and (ii) When water reacts with quick lime, calcium hydroxide is formed along with release of heat. Thus, it is an exothermic reaction. The process of diluting a concentrated...

(A) combination reaction

(C) Formation of compost from vegetable matter. Reactions given in option (A), (B) and (D) are examples of endothermic reactions and require energy in form of heat, light and electricity respectively....

i.   a. Calcium oxide reacts vigorously with water producing hissing sound. b. The container becomes hot asreaction is exothermic. ii.   The product formed is calcium hydroxide (slaked lime) and its chemical formula is...

i. Calcium oxide (quick lime) reacts with water to form calcium hydroxide (slaked lime) which is white in colour. ii. When green coloured ferrous sulphate crystals are heated, the residue of ferric...
