Does heating calcium carbonate produce an endothermic or exothermic reaction?

its an endothermic reaction, because the it broke the bonds of the calcium carbonate (CaCO3) in order to make calcium oxide (CaO) and Carbon dioxide (CO2).

Would you describe the reaction of calcium in water as being exothermic or endothermic?
The reaction between calcium and water is very exothermic.
Is the dissolving of calcium chloride endothermic or exothermic?
Both beacuse in such coditions it can be endothermic or exothermic.
Is the reaction of calcium chloride to ice a endothermic or exothermic reaction?
when CaCl2 is added to ice it becomes ionized slowly the ions become surrounded by water molecules the secondary types of bonding is responsible to evolve the heat so it is an exothermic reaction.
What is the chemical reaction between calcium carbonate and milk?
have any reaction between calcium carbonate & milk
Is the heating of calcium carbonate a synthesis reaction?
Heating of calcium carbonate (and the transformation in calcium oxide and carbon dioxide) is not a synthesis; it is a reaction of thermal dissociation.
Is solid calcium carbonate with water an endothermic or exothermic reaction?
Yes.
Would you describe the reaction of calcium in water as being exothermic or endothermic?
The reaction between calcium and water is very exothermic.
Does phenol red mixed with calcium chloride and baking soda turn out to be a exothermic or endothermic?
it results in a exothermic reaction
What is a sentence for the term endothermic reaction?
When you heat calcium carbonate, to make it under go thermal decomposition, this is an endothermic reaction, because you are driving heat into the calcium carbonate.
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.
Is the dissolving of calcium chloride endothermic or exothermic?
Both beacuse in such coditions it can be endothermic or exothermic.
Is an ionic compound exothermic?
A compound is never exothermic. Its reaction with some other substance is endothermic or exothermic like when calcium oxide reacts with water large amount of heat is evolved.
Is obtaining lime from limestone exothermic?
The hydratation of concentrated OH- and Na+ ions (by dilution) is exothermic, it gives an energetically prefered state of matter.(Hydratation is the extra surrounding of the ions by polar water molecules of the solvent).
Why does the temperature rise when hydrochloric acid is mixed with sodium hydroxide?
This is an EXOTHERMIC reaction. If you hold the reaction vessel it will feel warm. For all reactions there is an energy change. In this case when the sodium ions and the hydrogen ions associate with water molecules, there is a 'bond' forming. Bond forming releases energy, hence the heat/warmth. Conversely, when you want to break a bond e.g. calcium carbonate to form calcium oxide and carbon dioxide, you heat the calcium carbonate, you a driving in heat to break the bonds. It is Endothermic.
What chemical reaction takes place when drops of cold water are added to a white solid formed by heating calium calcium carbonate?
Exothermic reaction.
Is the reaction of calcium chloride to ice a endothermic or exothermic reaction?
when CaCl2 is added to ice it becomes ionized slowly the ions become surrounded by water molecules the secondary types of bonding is responsible to evolve the heat so it is an exothermic 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.
