When calcium carbonate reacts with an acid, it produces carbon dioxide gas, water, and a calcium salt. When calcium carbonate reacts with heat, it decomposes into calcium oxide (quicklime) and carbon dioxide gas. Lime stone, which is primarily composed of calcium carbonate, can undergo similar reactions.
What else can I help you with?
Is calcium carbonate carbonic acid?
No, calcium carbonate (CaCO3) is the calcium salt of carbonic acid (H2CO3). If a compound has the name of a metal in it (sodium, calcium, copper, etc) it is generally not an acid but a salt. A salt is formed when a metal ion or other positive ion takes the place of hydrogen in an acid.
How long does calcium carbonate take to thermally decompose?
Calcium carbonate typically decomposes when heated to form calcium oxide and carbon dioxide. This decomposition process usually takes place over a temperature range of 825-900 degrees Celsius and can vary in duration depending on factors like the heating rate and the particle size of the calcium carbonate.
What chemical reaction takes place when drops of cold water are added to a white solid formed by heating calium calcium carbonate?
When drops of cold water are added to a white solid formed by heating calcium carbonate (CaCO3), a chemical reaction occurs where calcium hydroxide (Ca(OH)2) is formed. This reaction is a hydration reaction where water molecules react with calcium oxide to produce calcium hydroxide.
What are the safety precautions of calcium carbonate?
Safety precautions for handling calcium carbonate include wearing appropriate personal protective equipment (PPE) such as gloves and goggles, avoiding inhalation of dust by using a dust mask or respirator, and ensuring good ventilation when working with the substance. It is also important to store calcium carbonate in a cool, dry place away from incompatible substances and follow proper disposal guidelines to prevent environmental contamination.
When calcium carbonate and hydrochloric acid react bubbles form. How do you know a reaction occurred?
You can tell that a reaction occurred because you observed the formation of bubbles, which indicates the release of a gas (carbon dioxide) as a product of the reaction between calcium carbonate and hydrochloric acid. The appearance of bubbles is a clear sign of a chemical change taking place.

What happens when calciun carbonate reacts with a neutral?
A reaction takes place I think. Neutral substance is a substance with a pH of 7 like pure water and when water reacts with calcium carbonate, calcium hydroxide and carbon 4 oxide is formed.
When CO2 mixes with limewater how do you know a chemical reaction took place?
When CO2 reacts with limewater (calcium hydroxide), the solution turns milky due to the formation of calcium carbonate, which is insoluble and precipitates out. This indicates a chemical reaction has taken place as a new substance with different properties has formed.
What happens when you place marble chips in vinegar?
Marble is primarily made of calcium carbonate. Vinegar has acid in it. When the weak acid contacts the calcium carbonate, it gives off bubbles of carbon dioxide gas, and eventually will erode the surface of the marble chips.
How does carbonation chemically weather rocks?
Ø Carbonation occurs on rocks which contain calcium carbonate such as limestone and chalk. Ø Carbon dioxide dissolved in rainwater forms weaker carbonic acid that reacts with insoluble calcium carbonate, changing it into soluble bicarbonate. This takes place when rain combines with carbon dioxide or an organic acid to form a weak carbonic acid which reacts with calcium carbonate (the limestone) and forms calcium bicarbonate. Ø The reactions as follows: Ø CO2 + H2O => H2CO3 Ø Carbon dioxide + water => carbonic acid Ø H2CO3 + CaCO3 => Ca (HCO3)2 Ø Carbonic acid + calcium carbonate => calcium bicarbonate
What type of reaction need to take place in the stomach before a person is likely to feel better?
Is it Calcium carbonate which neutralizes the acid.
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.

What is the balanced equation for limestone?
...Calcium Carbonate ===> Calcium Oxide(s) + Carbon Dioxide(g). CaCO3(s) + heat ===>CaO(s) + CO2(g). ...Calcium Oxide(s) + Water(l) ===> Calcium Hydroxide(s) CaO(s) + H2O(l) ===> Ca(OH)2(s). ...Calcium Hydroxide(aq) + Carbon Dioxide (g) ===> Calcium Carbonate(s) + Water (l) Ca(OH)2(aq) + CO2(g) ===> CaCO3(s) (suspension) + H2O(l) These equations do not need balancing, they are already balanced.
