When calcium carbonate (limestone, CaCO3) breaks down, carbon dioxide (CO2, gas) and calcium oxide (CO, solid) are formed
When the products are simpler substances than the reactants, it typically means that a decomposition reaction has occurred. In a decomposition reaction, a compound breaks down into simpler substances, such as elements or smaller compounds. This can be represented by the general equation: AB → A + B.
decomposition
The type of reaction in which a reactant gives simpler products is called a decomposition reaction. In a decomposition reaction, a single compound breaks down into two or more simpler substances.
chemical weathering by acid rain.
Hydrogen peroxide breaks down into water and oxygen through a decomposition reaction, where a single compound breaks down into two or more simpler substances. The reactants in this reaction are hydrogen peroxide (H2O2), and the products are water (H2O) and oxygen (O2).
A decomposition reaction results in the breakdown of a chemical into simpler substances. In this type of reaction, a single compound breaks down into two or more simpler substances.
A "decomposition" or "disproportionation" reaction.
Well, honey, when you mix lemon juice with limestone, you're causing a chemical reaction that breaks down the calcium carbonate in the limestone. This reaction forms calcium citrate, carbon dioxide, and water, which is definitely a chemical change. So, yes, adding lemon juice to limestone is a chemical change, no ifs, ands, or buts about it.
In a decomposition reaction, a single compound breaks down into two or more simpler substances. The products of a decomposition reaction are the simpler substances that result from the breakdown of the original compound.
A chemical reaction in which a chemical substance breaks down to form tow or more simpler substance is called decompositon reaction,answer by Hamid lolai from Gkti
When limestone is heated, it undergoes a chemical reaction called thermal decomposition, where it breaks down into calcium oxide (quicklime) and carbon dioxide gas. This is a chemical change because the chemical composition of the substance is altered during the process.
A chemical reaction that breaks down compounds into simpler products is called a decomposition reaction. In this type of reaction, a compound is broken down into individual elements or simpler compounds through various processes such as heat, light, or the addition of another compound. An example is the decomposition of hydrogen peroxide into water and oxygen gas.
