The reaction between calcium oxide (CaO) and water (H2O) to form calcium hydroxide (Ca(OH)2) is a synthesis reaction. In this type of reaction, two or more reactants combine to form a single product. The equation can be represented as: CaO + H2O → Ca(OH)2. This reaction is also classified as a hydration reaction, as water is added to a solid compound.
What else can I help you with?
Why does CaOH2 dissolve in water?
The oxide ion in CaO (O2-) is a very strong base, meaning it will easily take a hydrogen ion (H+) from a molecule. In water the oxide ion take a hydrogen ion from a water molecule, forming to hydroxide ions. O2- + H2O --> 2OH- In this reaction the oxide ion acts as a base and the water molecule as an acid, at least by the Bronsted-Lowry definition.
What is the products of the reaction CaOs H2Ol CaOH2s?
The reaction is: CaO(s) + H2O(l)--- --> Ca(OH)2(s) Ca(OH)2(s) is the product (at the right side of the reaction equation).
What happens when CaO dissolves in water?
this creats a base compound H2O+CaO-->H2CaO2 - Wrong. Correction; CaO(s) + H2O(l) ---> Ca[OH]2(aq) + heat Calcium hydroxide.
What type of reaction is cxhy equals co2 plus h2o?
Combustion reaction
What is the symbol equation for the reaction between calcium oxide and water?
CaO + H2O → Ca(OH)2 Calcium Oxide + water →Calcium hydroxide
What are the products of the neutralization reaction between HCI and CAOH2?
CaCl2 and H2O
Which is the properly balanced equation that shows the synthesis of limewater CaOH2 from calcium oxide and water?
CaO + H2O -> Ca(OH)2 If you are in doubt about this then count the number of atoms of each element on each side of the equation to verify that they correspond.
Which coefficients correctly balance the formula equation CaO plus H2O CaOH2?
The coefficients that correctly balance the equation CaO + H2O -> Ca(OH)2 are: CaO + 2H2O -> Ca(OH)2. Two water molecules are needed to react with one calcium oxide molecule to form one calcium hydroxide molecule.
What is the balanced equation for the reaction of sulfuric acid with calcium oxide?
This equation is CaO + H2SO4 = CaSO4 + H2O.
What is the balanced equation for calcium hydroxide yields calcium oxide and water?
The balanced equation for this reaction is: Ca(OH)2 --> CaO + H2O.
What is the balanced equation for the reaction between calcium oxide and water?
The balanced equation for the reaction between calcium oxide and water is: CaO + H2O -> Ca(OH)2
What is the balanced equation when calcium oxide reacts with water?
The balanced equation for the reaction between calcium oxide (CaO) and water (H2O) is: CaO + H2O -> Ca(OH)2. This reaction produces calcium hydroxide (Ca(OH)2) as the product.
Which of the following is an decomposition reactions?
A decomposition reaction is a type of chemical reaction where a compound breaks down into smaller substances. For example, the breakdown of hydrogen peroxide into water and oxygen gas is a decomposition reaction.
Balanced equation of calcium oxide and nitric acid?
This is an acid - base reaction: CaO + 2H+ + ( 2NO3- ) --> Ca2+ + H2O + ( 2NO3- )
What is lime meant by slaked?
It is the process of converting CaO to Ca(OH)2 by adding the CaO into water. The reaction is: CaO+H2O ---> Ca(OH)2 This reaction is highly exothermic and releases large amount of heat (63.7 kJoules for 1 mol of CaO used).
Cao plus h2o?
The reaction between CaO and H2O results in the formation of calcium hydroxide (Ca(OH)2) and heat. This process is known as hydration and is exothermic. Calcium hydroxide is a strong base and is commonly used in various applications such as in construction and agriculture.
What is the balanced equation of calcium oxide reacts with water to form calcium hydroxide?
how do you write a balanced chemical formula for this question CaO + H2O ---> Ca(OH)2
