What is formed when limestone is heated?
When heated, limestone forms two different things. It forms both calcium oxide and carbon dioxide. This occurs because limestone is made up of calcium carbonate.
If calcium metal is exposed to chlorine gas a reaction occurs What will be the product(s) of this reaction?
CaCl2
Copper carbonate and limewater?
Copper Carbonate (CuCO3) is heated up so that a decomposition reaction occurs, with the products being Copper (II) Oxide (CuO) and Carbon Dioxide (CO2). The chemical formula is: CuCO3 --> CuO + CO2. If proper apparatus is set up, the carbon dioxide should travel down a tube into limewater (Ca(OH)2), which react to create solid calcium carbonate (CaCO3, also known as chalk) and water (H2O). The calcium carbonate is the reason why the 'limewater' turns milky. This proves that there is CO2 present. The chemical formula for this is: Ca(OH)2 + CO2 --> CaCO3 + H2O.
When aqueous calcium nitrate is added to aqueous lithium sulfate a reaction occurs?
The products of the reaction are solid calcium sulfate and aqueous lithium nitrate.
Why is carbon dioxide produced when a carbonate react with acids?
Carbonates contain the carbonate ion CO32-. Acids release hydrogen ions, H+. In the presence of an an acid, the carbonate ion will form carbonic acid, H2CO3, an unstable molecule that readily breaks down into water and carbon dioxide.
What type of reaction occurs when copper carbonate is heated?
DECOMPOSITION
When heating marble what reaction occurs?
The gas is Carbon dioxide, formed by the decomposition of Calcium carbonate it the Marble or Limestone
What is the word equation for the endothermic reaction which occurs in lime kiln?
Calcium carbonate + heat= Calcium oxide + carbon dioxide is the word equation for the endothermic reaction which occurs in lime kiln.
What is an example of a chemical reaction that occurs quickly?
Ex.: burning of methane, reaction of calcium carbonate with acetic acid, reaction of sodium with water.
What is the chemical reaction which occurs between citric acid and calcium carbonate?
It fizzes and foams producing carbon dioxide bubbles.
What is formed when limestone is heated?

Why carbonate rocks are most affected by acid rain?
Limestone is calcium carbonate. The reaction that occurs when acid rain damages carbonate rocks is an acid-base reaction. Hydronium ions in the rain reaction with carbonate ions in the rock to form hydrogen carbonate, which is water soluble. The overall reaction is represented by H3O+ + CO32- => H2O + HCO3-
What happens when add the water to copper carbonate?
No reaction occurs
What chemical reaction take place when acid rain damages buildings made of carbonate rocks?
The reaction that occurs when acid rain damages carbonate rocks is an acid-base reaction.
What are endothermic reatcions?
Endothermic reactions are reactions in which the reactants have less energy than the products. This means that the reactants will require heat, in order for a reaction to take place. After an endothermic reaction occurs, the surrounding area around the reaction will feel cooler. examples are 1) electrolysis. 2) thermal decomposition of calcium carbonate in a furnace. 3) the reaction of ethanoic acid and sodium carbonate.
If calcium metal is exposed to chlorine gas a reaction occurs What will be the products of this reaction?
CaCl2
How does dry lime formed from limestone?
Limestone is crushed to a powder and heated in a furnace until the water of crystallisation is driven off. This is the water bonded within the calcium carbonate crystals. Once this is done it is called anhydrous(without water) calcium carbonate 'dry lime' or 'quicklime'. It is ground to a powder again and bagged.Upon mixing with water again an exothermic reaction occurs and produces a large amount of heat , enough to boil the added water.This is called slaked lime.
