Solid calcium oxide was taken in a container and water was added slowl

1.	Solid calcium oxide was taken in a container and water was added slowly to it. (i) State the two observations made in the experiment. (ii) Write the name and chemical formula of the product formed.
Answer» Solution :(i) FOLLOWING are the TWO observations: (a) Calcium oxide (CaO) reacts vigorously with WATER to FORM slaked lime. (b) The container becomes hot because a large amount of heat is released during this reaction. (iii) The PRODUCT formed is slaked lime for which the chemical formula is `Ca(OH)_(2)`. `underset("oxide")underset("Calcium")(CaO(s))+underset("Water")(H_(2)O(l))rarrunderset(("Calcium hydroxide"))underset("Slaked lime")(Ca(OH)_(2)(aq))`
