How many grams of calcium hydroxide can be produced from 312 g of CaO?
CaO has a gram molecular mass of 40.08 + 16.00 = 56.08. The reaction between CaO and water to produce calcium hydroxide, Ca(OH)2, occurs according to the equation CaO + H2O = Ca(OH)2. Therefore, the same number of moles of calcium hydroxide can be produced as the moles of CaO supplied. The gram molecular mass of Ca(OH)2 is 40.08 + 2 (16.00 + 1.008) = 74.10. Therefore, the mass of calcium hydroxide produced with have the same ratio to the mass of calcium oxide supplied as 74.10 has to 56.08, or 412 grams, to the justified number of significant digits.
Calcium oxide state?
The chemical formula of calcium oxide is CaO.
What is the chemical reaction between sodium acetate and sodium hydroxide?
There is no reaction between them: They only 'could exchange' the H+ and Na+ ions but the products are identical to the reactants.CH3COOH + CH3COONa --> CH3COONa + CH3COOH
What happens when calcium is added in water?
Calcium will react vigorously with water to produce calcium hydroxide and hydrogen gas. The equation is: Ca + 2H2O --> Ca(OH)2 + H2. This reaction is exothermic, therefore it produces heat.
What is the product when calcium is burnt?
Ca + 1/2 O2 => CaO, or quicklime. A more common reaction is the heating of calcium carbonate (limestone or marble) to produce oxygen and quicklime. CaCO3 => CaO +O2
Oxides will react with hydrochloric acid but not with aqueous sodium hydroxide?
co --carbon monoxide
What is the use of cao?
quick lime is used for drying out dead bodies, used in mass graves
Does calcuim oxide react with cold water?
Yes it does react. It forms Calcium hydroxide and makes the water hot. It is because the reaction between CaO and water is an exothermic reaction
How is limewater formed?
Lime water is a solution of sodium hydroxide. Lime water is formed by dissolving calcium oxide, CaO or quicklime in water.
How do CaO and CO2 react?
CaO + CO2 ==> CaCO3
What is slaked lime made from?
Soda lime is a mixture containing principally of calcium hydroxide and sodium hydroxide. Soda lime absorbs carbon dioxide.
Is oxygen in both lime and lye?
Yes, Lime is CaO (calcium oxide) and lye is NaOH or KOH (sodium or potassium hydroxide). In the above formulas O represents oxygen.
How does Ca react with O?
CaO
What is CaOH?
Calcium hydroxide, commonly known as limewater, it is made by adding CaO to H2O
Give equations to represent the following reactions.(a) Borax is heated with CaO?
The chemical equation to represent the reaction between borax (Na2B4O7) and CaO (calcium oxide) when heated is: Na2B4O7 + CaO → CaB4O7 + Na2O In this reaction, borax and calcium oxide react to form calcium tetraborate (CaB4O7) and sodium oxide (Na2O) as the products.
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.
Why is limestone cooled in a dry argon atmosphere after being heated?
Limestone, when heated produces calcium oxide (CaO) and carbon dioxide (CO2). CaO is highly reactive and will combine with CO2 from the atmosphere to reverse the above process. It will also react with any water vapour in the atmosphere to form calcium hydroxide (CaOH). These reactions can be prevented by allowing the CaO to cool in an inert environment such as that provided by argon.
