The reaction is as follows: Ca(OCl)2 + H2CO3 (carbonic acid in water) = CaCO3 + 2HOCL (hypochlorous acid) 2HOCL + organic matter = 2HCL + O2 (nascent or released oxygen) 2HCL + CaCO3 = CaCl2 + H20 + CO2 It is the nascent oxygen that actually carries out the oxidation / disinfection process.

When aqueous calcium nitrate is added to aqueous lithium sulfate a reaction occurs?
When aqueous calcium nitrate is added to aqueous lithium sulfate, a double displacement reaction occurs. The calcium and lithium ions switch places to form calcium sulfate and lithium nitrate. This reaction results in the formation of two new compounds: CaSO4 and LiNO3.
If calcium metal is exposed to chlorine gas a reaction occurs What will be the product(s) of this reaction?
The reaction between calcium metal and chlorine gas will produce calcium chloride as the product. This is represented by the chemical equation: Ca + Cl2 -> CaCl2.
Chemical reaction between calcium and copper sulphate?
When calcium metal is added to a solution of copper sulfate, a single displacement reaction occurs. The more reactive calcium displaces the less reactive copper from the copper sulfate solution. This results in the formation of calcium sulfate and elemental copper. The balanced chemical equation for this reaction is: Ca + CuSO4 -> CaSO4 + Cu.
What type of reaction occurs when calcium carbonate is heated?
When calcium carbonate is heated, it undergoes a chemical reaction called thermal decomposition. This results in the formation of calcium oxide (quicklime) and carbon dioxide gas being released as a byproduct.
What happens when you add dilute hcl to to calcium chloride?
When dilute hydrochloric acid (HCl) is added to calcium chloride (CaCl2), a double displacement reaction occurs. The products of this reaction are calcium chloride and water. Some of the calcium chloride may remain in solution while other parts may precipitate out, depending on the concentrations and quantities of the reactants.
What reaction occurs when mixing calcium hypochlorite with nitric acid?
When calcium hypochlorite is mixed with nitric acid, chloric acid is formed. This reaction may release chlorine gas, which is toxic and can be dangerous if inhaled. Therefore, it is important to carry out this reaction in a well-ventilated area and with proper safety precautions.
What reaction occurs when mixing sodium hypochlorite with nitric acid?
When sodium hypochlorite (NaOCl) is mixed with nitric acid (HNO₃), a chemical reaction occurs that produces chlorine gas (Cl₂), which is toxic and can be hazardous. The reaction can be represented by the equation: 3 NaOCl + 6 HNO₃ → 3 NaNO₃ + 3 Cl₂ + 3 H₂O. This reaction is highly exothermic and can pose safety risks, so it should be avoided in uncontrolled environments. Always handle such chemicals with caution and appropriate safety measures.
What reaction occurs on addition of NaOCl and PbO2?
When NaOCl (sodium hypochlorite) and PbO2 (lead dioxide) are mixed, a redox reaction occurs where sodium hypochlorite is reduced to chloride ions while lead dioxide is oxidized to lead(IV) chloride. The overall reaction can be represented as: 2NaOCl + PbO2 -> 2NaCl + PbCl4 + O2
What happens when calcium oxide is added to hcl?
When calcium oxide is added to hydrochloric acid, a chemical reaction occurs where calcium oxide reacts with the acid to form calcium chloride and water. The balanced chemical equation for this reaction is CaO + 2HCl -> CaCl2 + H2O. Heat is produced during this exothermic reaction.

What reaction occurs when sulfuric acid and limestone mix?
it forms calcium sulphate
If calcium metal is exposed to chlorine gas a reaction occurs What will be the products of this reaction?
The reaction between calcium metal and chlorine gas will form calcium chloride, which is a white crystalline solid. This reaction is highly exothermic and releases a significant amount of heat.
What happens when sodium hypochlorite and hydrochloric acid are mixed together?
When sodium hypochlorite and hydrochloric acid are mixed together, a chemical reaction occurs that produces chlorine gas, water, and salt. This reaction is exothermic, meaning it releases heat, and can be dangerous if not done carefully in a controlled environment.

Calcium carbonate + heat= Calcium oxide + carbon dioxide is the word equation for the endothermic reaction which occurs in lime kiln.
What happens when you mix sulphuric acid with calcium hydroxide?
When you mix sulphuric acid with calcium hydroxide, a neutralization reaction occurs. Calcium sulfate and water are formed as the products of this reaction. The calcium sulfate is a white insoluble solid that precipitates out of the solution.
