i think its calcium hydroxide x
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 calcium oxide is: calcium oxide + water → calcium hydroxide.
This chemical reaction is: CaO + H2O = Ca(OH)2.
The word equation for the extraction of calcium from calcium oxide by electrolysis is: Calcium oxide (solid) -> Calcium (liquid) + Oxygen gas.
Ca+O=CaO
The word equation for calcium reacting with oxygen is: calcium + oxygen → 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.
The word equation for the reaction is: calcium oxide + hydrochloric acid → calcium chloride + water The chemical equation is: CaO(s) + 2HCl(aq) → CaCl2(aq) + H2O(l)
When quick lime (Calcium Oxide , CaO) reacts with water (H2O) then the exothermic reaction takes placeCaO +H2O ------> Ca(OH)2 + heat evolves
to get calcium hydroxide: Quicklime (calcium oxide) + water = slaked lime (calcium hydroxide) the calcium oxide has a chemical reaction with water to get the calcium hydroxide hope this helps :)
Similar to Sodium and Water. Efferevescence and an alkali product . Ca(s) + 2H2O(l) = Ca(OH)2 (aq) + H2(g). NB Where sodium is a Group '1' metal , it has only ONE hydroxide attached. Calcium is a Group '2' meta; , so it has TWO hydroxides attached.
I'm sure it's an oxidation reaction. calcium + oxygen gas ---> Calcium oxide
