2Ca(s) + Os(g) = 2CaO (s)
The word equation for calcium oxide is: calcium oxide + water → calcium hydroxide.
The balanced symbol equation for calcium oxide (CaO) with water (H2O) forming calcium hydroxide (Ca(OH)2) is: CaO + H2O → Ca(OH)2
The symbol equation for the reaction between calcium and oxygen is: 2Ca + O2 -> 2CaO. This represents the combination of two atoms of calcium with one molecule of oxygen to form two molecules of calcium oxide.
CaCO3(s) --> CaO(s) +CO2(g) enthalpy is +178 kJ molˉ¹
Calcium oxide and Water = Calcium hydroxide(Slaked lime/ lime water). . Here is the BALANCED reaction equation CaO(s)+ H2O(l) = Ca(OH)2(aq)
CaO + H2O → Ca(OH)2 Calcium Oxide + water →Calcium hydroxide
The word equation for calcium oxide is: calcium oxide + water → calcium hydroxide.
Calcium oxide and Water = Calcium hydroxide(Slaked lime/ lime water). . Here is the BALANCED reaction equation CaO(s)+ H2O(l) = Ca(OH)2(aq)
The word equation for the extraction of calcium from calcium oxide by electrolysis is: Calcium oxide (solid) -> Calcium (liquid) + Oxygen gas.
The balanced symbol equation for calcium oxide (CaO) with water (H2O) forming calcium hydroxide (Ca(OH)2) is: CaO + H2O → Ca(OH)2
The symbol equation for the reaction between calcium and oxygen is: 2Ca + O2 -> 2CaO. This represents the combination of two atoms of calcium with one molecule of oxygen to form two molecules of calcium 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.
CaCO3(s) --> CaO(s) +CO2(g) enthalpy is +178 kJ molˉ¹
Ca+O=CaO
Calcium carbonate thermally decomposes when heated to form calcium oxide powder and carbon dioxide gas. The word equation: calcium carbonate --> calcium oxide + carbon dioxide As a symbol equation: CaCO3 --> CaO + CO2
CaO
The word equation for calcium reacting with oxygen is: calcium + oxygen → calcium oxide.
