May 27, 2018· Here is the required equation CaCO3----- CaO + CO2 Since reactant is equal to the product. Hence the chemical equation is fully balanced.
What is the balanced symbol equation for calcium oxide with water goes to hydroxide? CaO + H2O -> Ca(OH)2 Read More. Asked in Elements and Compounds
Calcium Oxide is commonly known as quicklime or Lime water or burnt lime and is a widely used chemical compound. The formula for lime water is Ca(OH)2. Study the .
Dec 19, 2013· The ionic formula for calcium oxide is simply CaO. Why is this the case? The Calcium ion is an Alkaline earth metal and wants to give up the 2 s orbital elections and become a +2 cation. Oxygen has six valence electrons and is looking to gain two electrons to complete the octet (8) electron count in the valence shell making it a -2 anion. When the charges of the Calcium +2 and the Oxygen .
Nov 11, 2014· 2:35formula so we remove the ones leaving us 2:39with the formula CA 0 2:42which will compact and right as the 2:44final formula for calcium oxide 2:49checking charges we have one CA 2 .
It is tricky question for students in exams and some have failed :D CaO is basic oxide and solid. HCl is gaseous itself and when you say "HCl acid", it means HCl being present in water. Right to the process : When you add CaO into HCl acid, CaO r...
No, calcium oxide is not poisonous. Exposed to air, it will quickly convert to calcium hydroxide and over time to calcium carbonate. Calcium hydroxide is in every cement, concrete, render, most plasters, some paints, as well as being used in fertilizers and in drinking water treatment, rest assured, that you cannot avoid exposure to it.
