Does heating calcium carbonate produce an endothermic or exothermic reaction?
Heating calcium carbonate (CaCO3) produces an endothermic reaction because energy is absorbed in the form of heat to break the bonds between the calcium, carbon, and oxygen atoms in the compound. This results in the decomposition of calcium carbonate into calcium oxide (CaO) and carbon dioxide (CO2).
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.
Is the dissolving of calcium chloride endothermic or exothermic?
The dissolving of calcium chloride in water is exothermic, meaning it releases heat. This is because the process of dissolving calcium chloride is accompanied by the breaking of ionic bonds, which releases energy in the form of heat.
Is the dissolution of calcium hydroxide exothermic or endothermic?
Exothermic: Heat is given off as one of the products. The container holding the reactants and the products gets hot during the reaction. Use approximately 5 mL of 6M HCl and add to a testtube containing a small peice of mossy Zn. Immediately place a thermometer in the testtube and you will see a quick rise in temperature. This rise in temperature indicates that heat is given off which is a clear sign of an exothermic reaction. Hope this helps!!
Mix calcium oxide with water and then what happens?
Well, The chemical reaction when calcium is placed with water is a fizzing. It fizzes and also "produces" heat. Not sure what the chemical formula would be called however. Calcium Hydroxide possibly
Is Calcium chloride in water is endothermic or exothermic?
The dissolution of calcium chloride in water is exothermic, meaning it releases heat. This reaction results in an increase in temperature of the solution.
Is reacting calcium carbonate with hydrochloric acid endothermic or exothermic?
Reacting calcium carbonate with hydrochloric acid is an exothermic reaction. It releases heat energy as the reaction proceeds, making the surroundings warmer.
Does phenol red mixed with calcium chloride and baking soda turn out to be a exothermic or endothermic?
The reaction between phenol red, calcium chloride, and baking soda is endothermic. The mixture will absorb heat from its surroundings as it undergoes the reaction, causing the temperature of the mixture to decrease.
Do self heating cans warm up their contents using an exothermic or endothermic reaction?
Self-heating cans warm up their contents using an exothermic reaction. This reaction typically involves mixing water with quicklime (calcium oxide), which generates heat as it reacts to form calcium hydroxide.
Is calcium carbonate being heated into calcium oxide and carbon dioxide endothermic or exothermic?
The reaction of calcium carbonate being heated into calcium oxide and carbon dioxide is an endothermic reaction because it requires the input of energy to break the bonds in the calcium carbonate molecule and form the products.
Is solid calcium carbonate with water an endothermic or exothermic reaction?
The reaction of solid calcium carbonate (CaCO3) with water is an endothermic process because it requires energy input to break the bonds between the calcium, carbon, and oxygen atoms in the calcium carbonate molecule and form new bonds with the water molecules.
Does heating calcium carbonate produce an endothermic or exothermic reaction?
Heating calcium carbonate (CaCO3) produces an endothermic reaction because energy is absorbed in the form of heat to break the bonds between the calcium, carbon, and oxygen atoms in the compound. This results in the decomposition of calcium carbonate into calcium oxide (CaO) and carbon dioxide (CO2).

How can endothermic and exothermic reactions work alike?
Endothermic and exothermic reactions are similar in that both have reactants and products. They are different in that exothermic reactions release energy through reacting and endothermic reactions absorb it.
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).
