Calcium oxide is a drying agent---it is used to wick away any water that wants to condense into the reaction (because ammonia is extremely hydroscopic).

When you add water to calcium oxide what does it give?
Calcium Hydroxide is the product when Calcium Oxide is reacted with water. It is an exothermic reaction liberating heat. This process is called slaking. CaO + H2O -----> Ca(OH)2.
What would a farmer do if his soil was to acidic?
He would add a base such as lime (calcium oxide).
Why is calcium used in cement?
As Calcium Has been used for Building Purpose And For the Similar purpose it is Using IN Cement Which Depend upon its Bonding Property.It Actually react with Water in the Presence of Sesqui oxide(oxygen with Cation in (3:2) ratio) and form a Complex Compound With water of Crystalline Which have A power to hold the Material and So called cement.
What happens when calcium is added in water?
Calcium will react vigorously with water to produce calcium hydroxide and hydrogen gas. The equation is: Ca + 2H2O --> Ca(OH)2 + H2. This reaction is exothermic, therefore it produces heat.
How can I write the balanced chemical reaction for making CaCl2?
You could add hydrochloric acid to calcium to form calcium chloride and hydrogen gas. 2HCl + Ca → CaCl2 + H2
What do you get when you add water to calcium oxide?
It's an exothermic reaction that produces calcium hydroxide.
What is a lime?
a type of citrus fruit and calcium oxide that is greenLime is Calcium Carbonate (usually upto 96% plus other metallic elements) in it's natural form, when you burn it, it becomes calcium oxide, generally speaking for building you then add it to water making calcium hydroxide then it resets back to calcium carbonate... thus the lime cycle.
What happens if you add too much water to calcium oxide?
it will go cold
What color do you get when you add water and calcium oxide?
it looks like nonfat milk
How to increase the percentage of calcium oxide in a powder sample?
Add CaO to the powder.
When you add water to calcium oxide what does it give?

What would a farmer do if his soil was to acidic?
He would add a base such as lime (calcium oxide).
What happens when you add calcium oxide and sulphuric acid?
CaO + H2SO4 -> CaSO4 + H2O Possible reaction. Forming the salt calcium sulfate and water.
What is slake lime?
Quicklime is calcium oxide - CaO and slaked lime is calcium hydroxide - Ca(OH)2. CaCO3--------------CaO + CO2 This reaction occur at high temperature; mixing calcium oxide with water, the hydroxide is obtained.
How is slaked lime produced from limestone?
Heat it, the limestone (calcium carbonate) loses carbon dioxide to leave qucklime (calcium oxide). Add water to form slaked lime (calcium hydroxide).
Which is more basic calcium carbonate or calcium oxide?
Calcium oxide is a compound of calcium and oxygen and has the formula CaO. It is very basic (alkaline) and will react with water to form calcium hydroxide, Ca(OH)2 which is a strong base. Calcium oxide is commonly called lime or quicklime.Calcium carbonate is a compound of calcium, carbon, and oxygen with the formula CaCO3. It is mildly basic and will not react with water nor is it water soluble. It is commonly called calcite, limestone, or marble.
What is lime?
Lime is Calcium Carbonate (usually upto 96% plus other metallic elements) in it's natural form, when you burn it, it becomes calcium oxide, generally speaking for building you then add it to water making calcium hydroxide then it resets back to calcium carbonate... thus the lime cycle.
