Which of the following is not a product of the reaction between calcium carbonate and hydrochloric acid?
|
|
CaCl
|
|
|
H2O
|
|
|
CO2
|
|
|
CaCl2
|
Explanation:
Detailed explanation-1: -The balanced equation of CaCO3 + HCl → CaCl2 + H2O + CO2 is CaCO3 (s) + 2HCl(aq) → CaCl2 (s) + H2O(aq) + CO2(g).
Detailed explanation-2: -Calcium carbonate reacts with aqueous HCl to give CaCl2 and CO2 according to the reaction-CaCO3(s)+2HCl(aq)→CaCl2(aq)+CO2(g)+H2O(l)The mass of CaCO3 which is required to react completely with 25 ml of 0.75 M HCl is: Q.
Detailed explanation-3: -Definition: compounds exchange ions to form 2 new compounds General Equation for a DoubleReplacement Reaction: AB + CD > AD + CB Example of a DoubleReplacement Reaction: CaCO3 + 2HCl > CaCl2 + H2CO3 Calcium and hydrogen switch places.
