What happens when calcium oxide reacts with water?
What happens when calcium oxide reacts with water?
Calcium oxide reacts vigorously with water to produce slaked lime (calcium hydroxide) releasing a large amount of heat. In this reaction, calcium oxide and water combine to form a single product, calcium hydroxide.
What type of reaction is CaO s H2O → Ca OH 2?
combination reaction
Answer: This reaction is a combination reaction, as calcium oxide and water combines to form a single product that is calcium hydroxide.

What type of reaction is this Ca S 2H2O L → Ca OH 2 AQ H2 G?
redox reaction
The reaction Ca+2H2O⟶Ca(OH)2+H2 is an example of redox reaction.
What is the formula of calcium oxide?
CaOCalcium oxide / Formula
Calcium oxide, commonly known as lime, is a chemical compound with the formula CaO. Calcium oxide, also known as quicklime, is an alkaline substance that has been in use since the medieval age. It is believed that quicklime is one of the oldest chemicals known to the human race.
What is calcium oxide water?
Calcium hydroxide, also called slaked lime, Ca(OH)2, is obtained by the action of water on calcium oxide. When mixed with water, a small proportion of it dissolves, forming a solution known as limewater, the rest remaining as a suspension called milk of lime.
Is CaO H2O –> Ca OH 2 a redox reaction?
question. Answer: Yes, it is a redox reaction.
What is the molecular weight of caco3?
