Is the reaction between calcium and hydrochloric acid exothermic or endothermic?
1 The reaction of calcium oxide with hydrochloric acid is an
exothermic reaction
. CaO(s) + 2HCl(aq) → CaCl2(aq) + H2O(l) In an experiment to investigate this reaction, the following procedure was carried out.
Why is the reaction of CaCO3 with HCl vigorous?
Due to the formation of carbon dioxide, there would be effervescence. The solid will start to disappear as it is reacting to form an aqueous salt.
If the acid is highly concentrated
, the reaction would be more vigorous as there would be more HCl molecules to react with the CaCO
3
.
Is CaCO3 an acid or base?
Answer: calcium carbonate is a salt, it is
neither acid nor base
.
What type of reaction is H2 Cl2 → 2hcl?
Explanation: Two elements H
2
and Cl
2
combine to form a single compound, HCl. Hence, it is a
combination reaction
. As two elements combine to form a compound, it is an element – element combination.
What is the reaction between calcium oxide and hydrochloric acid?
It happens when calcium oxide reacts with HCl, it
produces a salt called calcium chloride and water
.
How would you describe the different types of chemical reaction?
The five basic types of chemical reactions are
combination, decomposition, single-replacement, double-replacement, and combustion
. Analyzing the reactants and products of a given reaction will allow you to place it into one of these categories. Some reactions will fit into more than one category.
What happens when CaO reacts with HCl?
When calcium oxide reacts with HCl, it
produces a salt called calcium chloride and water
.
What type of reaction is CaCO3 CaO CO2?
(a)
Decomposition
: A substance breaks down to smaller species. [e.g. CaCO3(s) → CaO(s) + CO2(g) Decomposition of limestone to calcium oxide (quicklime) and carbon dioxide on heating.]
What gas is produced during the reaction of CaCO3 and HCl?
Like all metal carbonates, calcium carbonate reacts with acidic solutions to produce
carbon dioxide gas
. It is this reaction that is responsible for limestone fizzing when dilute hydrochloric acid is placed on its surface.
What is the product of CaCO3 2 HCl?
CaCO3 + 2 HCl →
CaCl2 + H2O + CO2

Is HCl and CaCO3 a double displacement reaction?
Originally Answered: What is precipitate in the reaction of HCL+CaCO3? The following reaction is a
double displacement reaction
as in it the Cl and CO3 get exchanged from their corresponding cation. There’s no formation of precipitation in this reaction while CO2 get evolved along with the formation of CaCl2 and water.
What is example of endothermic reaction?
Endothermic Processes
Melting ice cubes
.
Melting solid salts
.
Evaporating liquid water
.
Converting frost to water vapor
(melting, boiling, and evaporation, in general, are endothermic processes.
How do particle size affect the rate of chemical reaction?
Surface Area / Particle Size
Breaking the reactant into smaller pieces increases the surface and more particles are exposed to the reaction mixture
. This results in an increased frequency of collisions and therefore a faster rate of reaction.
Which of the following reaction is an endothermic reaction?
The endothermic reaction is (iv)
decomposition of calcium carbonate to form quick-lime and carbon dioxide
. Explanation: In this reaction, calcium carbonate decompose in the presence of energy formed by the heat (thermal decomposition).
Is Heating caco3 to form CaO and co2 endothermic or exothermic?
No, CaCO
3
(s) → CaO(s) + CO
2
(g) is an
endothermic reaction
. This is the decomposition of limestone to calcium oxide (quicklime) and carbon dioxide on heating.
What type of reaction is sulfuric acid and calcium carbonate?
It’s
a typical neutralization reaction
. It will result in the formation of a sparingly soluble salt, calcium sulphate and of course, water. Equation; Ca(OH)2(aq)+H2SO4(aq)—→ CaSO4(s)+2H2O(l).. So when calcium carbonate reacts with sulfuric acid, it forms water, carbon dioxide and calcium sulfate.
Is H2CO3 an acid or a base?
H2CO3 is
a weak acid
that dissociates into a proton (H+ cation) and a bicarbonate ion (HCO3- anion). Furthermore, the conjugate base of carbonic acid, which is the bicarbonate ion, is a relatively good base.
Is CaCl2 an acid or base?
Dear student, CaCl2 is a
salt of strong acid HCl and strong base Ca(OH)2
. Thus it forms a neutral solution when dissolved in water.

Does HCl react with CaCl2?
Balancing Strategies: In this reaction
Calcium (Ca) metal is reacting with Hydrochloric acid
(HCl). the Ca replaces the H in HCl and we end up with CaCl2 and H2. Overall it is a fairly straightforward equation to balance. Start by changing the coefficient on HCl to balance the H and Cl atoms.
