If 18.52 g of limestone decomposes by heat to give 8.19 g of calcium oxide and carbon dioxide gas what is the mass of carbon dioxide produced?

This kind of a question is known as a "mass balance equation" in that the mass of the sum of the reactants must equal the mass of the sum of the products. (In fact, there will be some mass lost during exothermic reactions - but it is negligible from the perspective of the question). So, in this case, you already have a limiting factor which is the mass of limestone (18.52 g). Therefore, you know that the sum of the masses of the products must be equal to 18.52). Now, all the information you need to answer your question is actually given to you in your question. Read and consider your question carefully, and think about what has just been said.

What decomposes limestone?
heat. limestone (CaCO3) ---> carbon dioxide (CO2) + calcium oxide (CaO)
When limestone is heated it become sandstone?
No, limestone is a carbonate rock formed through chemical precipitation. Sandstone is a classification used for sedimentary rocks ranging in various sizes and compositions. Limestone is CaCO3 where as sandstones are usually quartz (SiO2) and feldspars.
When Calcium carbonate is heated .?
It decomposes into calcium oxide and carbon dioxide...
What gas is produced when acid rain falls on a limestone statue?
Carbon dioxide is produced.
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.
What decomposes limestone?
heat. limestone (CaCO3) ---> carbon dioxide (CO2) + calcium oxide (CaO)
What type of reaction is limestone when heated?
Heating of limestone is a decomposition reaction as limestone decomposes to give calcium oxide and carbon dioxide.
What are the products when limestone is heated strongly?
carbon dioxide calcium oxide (quicklime) CaCO3 > CaO + CO2
What happens if you heat limestone?
Limestone is calcium carbonate (CaCO3) which when heated to above 840°C decomposes into calcium oxide (CaO) while releasing carbon dioxide (CO2) according to the equation: CaCO3 → CaO + CO2
How does high temperature affect limestone?
At high temperature, limestone undergoes thermal decomposition. The word equation is calcium carbonate decomposes when heated to calcium oxide and carbon dioxide. The chemical equation is CaCO3 + heat --> CaO + CO2.
How is slaked lime produced from limestone?
Heat it, the limestone (calcium carbonate) loses carbon dioxide to leave qucklime (calcium oxide). Add water to form slaked lime (calcium hydroxide).
What is formed when calcium carbonate decomposes?
quicklime (calcium oxide) is formed when calcium carbonate decomposes, as well as releasing carbon dioxide
How do limestone absorb carbon dioxide?
yes it does. it absorbs lots of the stuff.. it very usefull it made out of crushed up sea shell carbon dioxide a colourless gas and can be tested by bubbling it through lime water.
What happens to calcium carbonate when heated?
It decomposes into calcium oxide and carbon dioxide
How is limestone produced and what it is commonly used for?
Limestone is mainly calcium carbonate, CaCO3. When heated, it breaks down to form calcium oxide and carbon dioxide. Calcium oxide reacts with water to produce calcium hydroxide. Limestone and its products have many uses: for example, in mortar, cement, concrete and glass.
Is carbon dioxide produced from calcium carbonate and hydrochloric acid?
the short answer is Yes...2HCI + CaCO3 becomes CACL2 + H2CO3 the H2CO3 decomposes to water and CO2
What mass of carbon dioxide will be produced?
Full question: Ordinary chalkboard chalk is a solid mixture with limestone (calcium carbonate) and gypsum (calcium sulfate) as its principal ingredients. The limestone dissolves in dilute hydrochloric acid, producing calcium chloride, carbon dioxide, and water. 1.) Gypsum does not react with HCl. If a 5.05g piece of chalk that is 72.0% calcium carbonate is dissolved in excess HCl, what mass of carbon dioxide will be produced? 2.) Determine the mass percent of calcium carbonate in a 4.38g piece of chalk that yields 1.31g carbon dioxide when it reacts with excess HCl?
