It is CaO, not Ca2. And there is no such thing as calcium II, because the Ca2+ cation that calcium forms is the ONLY cation that it forms. This is true for almost all of the all of the alkali and alkaline earth metals. So it would just be Calcium Oxide, even though it has a plus 2 charge. The (II) is only necessary if the element forms more than one type of ion.
CaO + H20 ---> CO2 + H2 <--- This is wrong, where have the Calcium atoms gone and the Carbon atoms appeared from?
Correct:
Ca (s) + 2H₂O (l) --> Ca (OH)₂ (aq) + H₂ (g) <--- this is wrong, she/he asked for the reaction of calcium oxide with water not just calcium
It's: CaO + H2O = Ca(OH)2
The chemical formula for calcium oxide is CaO. It is composed of one calcium atom and one oxygen atom.
Ca(OH)2
Ca needs two more electrons to have a full outer shell, OH needs one electron to have a full valence. So in order to have a ratio of 1:1, you need 2OH.
CaO . Otherwise known as Lime or Quicklime.

What is the word equation for calcium oxide?
The word equation for calcium oxide is: calcium oxide + water → calcium hydroxide.
What is the word equation of calcium oxide and water?
The word equation for the reaction between calcium oxide and water is: calcium oxide + water → calcium hydroxide.
What the chemical name for quicklime?
The chemical name for quicklime is calcium oxide (CaO).
What is the cation of calcium oxide?
Calcium and Oxygen are the atoms in Calcium Oxide.
How calcium oxide is formed in a blast furnace?
Calcium oxide is formed in a blast furnace as a byproduct of the smelting process when limestone, which contains calcium carbonate, is added to the furnace. The intense heat of the furnace decomposes the calcium carbonate into calcium oxide and carbon dioxide. The calcium oxide is then collected as a solid residue.
What calcium oxide in formulae?
CaO is the formula for calcium oxide.
What is the word equation for extraction of calcium from calcium oxide by electrolysis?
The word equation for the extraction of calcium from calcium oxide by electrolysis is: Calcium oxide (solid) -> Calcium (liquid) + Oxygen gas.
What is calcium oxide?
calcium oxide is calcium combine whit oxygen
How much elemental Calcium is there in Calcium oxide?
There is no elemental calcium in calcium oxide. Calcium oxide is a compound made up of calcium and oxygen atoms bonded together. When calcium oxide reacts with water, it forms calcium hydroxide, which contains calcium ions but not elemental calcium.
What does calcium oxide mean?
CaO is calcium oxide
Is calcium oxide illegal?
Calcium oxide is legal.
What is the word equation for calcium plus iron oxide?
The word equation for calcium plus iron oxide is: calcium + iron oxide → calcium oxide + iron. In this reaction, calcium displaces iron in iron oxide to form calcium oxide and elemental iron. This type of reaction is known as a displacement reaction, where a more reactive element displaces a less reactive element in a compound.
What is the word equation for calcium oxide?
The word equation for calcium oxide is: calcium oxide + water → calcium hydroxide.
What is the name of CaO?
The chemical name for CaO is Calcium Oxide.The common name for calcium oxide is quick lime.
What colour is calcium oxide?
Pure calcium oxide is white.
What is the word equation of calcium oxide and water?
The word equation for the reaction between calcium oxide and water is: calcium oxide + water → calcium hydroxide.
What elements are found in calcium oxide?
Calcium oxide (CaO) contain calcium and oxygen.
