What does potassium chlorate yield?
Potassium chlorate, when heated strongly, decomposes into potassium chloride and oxygen gas. This decomposition reaction is often used to produce oxygen gas in chemistry experiments or industrial processes.
What substances are created when calcium carbonate is heated very strongly in an open crucible?
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
What happens when Hg oxide is heated?
When mercuric oxide is strongly heated in a hard glass tube, it decomposes, globules of mercury collect in the cooler part of the tube and oxygen gas is evolved. It may be collected over mercury in a pure and dry state.
What substance is made when limestone and clay are heated together?
When limestone and clay are heated together, they form a mixture called cement clinker. This clinker is then ground into a fine powder to produce cement, which is used as a binding agent in concrete.
What compounds are formed when caco3 is heated strongly?
CaCO3 --> CO2 + CaO
What happens when ZnCO3 is heated in the absence of air?
When ZnCO3 is heated in the absence of air, it undergoes thermal decomposition. This results in the formation of zinc oxide (ZnO) and the release of carbon dioxide gas (CO2).
When lead nitrate is heated strongly what does it evolve?
When lead nitrate is heated strongly, it decomposes to form lead oxide, nitrogen dioxide gas, and oxygen gas.
Which gas is evolved when lead nitrate is strongly heated?
When lead nitrate is strongly heated, it decomposes to produce nitrogen dioxide gas (NO2), which is a brown gas with a sharp, acrid odor.
What decomposes when heated to give zinc oxide?
Zinc carbonate decomposes when heated to give zinc oxide.
What happens if sodium metabisulphite is strongly heated?
When sodium metabisulphite is strongly heated, it decomposes to release sulfur dioxide gas and sodium sulfite. This decomposition reaction is endothermic, requiring heat to break down the compound. Sodium metabisulphite is commonly used as a food preservative and in various industrial processes.
What happens when ozone is heated?
Ozone when heated gets decomposed. It decomposes into oxygen.
What happen when lead dioxide is heated?
Lead dioxide decomposes upon getting heated.
When KBrO3is heated it decomposes into KBr what is the balanced equation?
When KBrO3is heated it decomposes into KBr and oxygen.The balanced equation is 2 KBrO3 -> 2 KBr + 3 O2.
What could be the controlled variables in a lab where you heat NaHCO3 with a burner to find out what amount of the gas CO2 is formed?
Many aspects of this procedure could be varied, among them:length of time substance is heatedwhat substance is heated, alternatives might be Na2CO3 and NaOHhow strongly substance is heated
When heated potassium nitrate decomposes to form?
When heated, potassium nitrate decomposes to form potassium nitrite and oxygen gas. This decomposition reaction is represented by the following equation: 2KNO3 (s) → 2KNO2 (s) + O2 (g)
What does CuCl2 decompose to when heated?
It decomposes to Cl2 and Cu there is another reaction as well. decomposes to CuCl(s) and 0.5Cl2(g)
What is obtained when natural gas is strongly heated?
when natural gas is strongly heated, hydrogen(H) and carbon(C) are obtained.
