Question

A solution reacts with crushed egg shells giving carbon dioxide (co2) the *Solution* contains!!!a)HCl.            b)H2SO4   c)CH3COOH d)HCOOH Explain your answer dear?

Answer

Egg shells made of calcium carbonate CaCO3.
dilute HYDROCHLORIC ACID dissolves the caco3 and makes the shell soft.

Answer

Answer

Solution:
The solution that reacts with crushed egg shells and produces carbon dioxide gas can be determined by analyzing the chemical reactions that occur between the solution and the egg shells.

The reaction between an acid and a carbonate compound, such as the calcium carbonate found in egg shells, typically produces carbon dioxide gas. Therefore, the solution must contain an acid in order to react with the egg shells and release carbon dioxide.

Let's analyze the options given:

a) HCl (Hydrochloric acid): HCl is a strong acid that can react with calcium carbonate to produce carbon dioxide gas. This reaction is represented by the following equation:
HCl + CaCO3 -> CaCl2 + CO2 + H2O

b) H2SO4 (Sulfuric acid): Like HCl, sulfuric acid is also a strong acid that can react with calcium carbonate to produce carbon dioxide gas. The reaction is similar to the one with hydrochloric acid:
H2SO4 + CaCO3 -> CaSO4 + CO2 + H2O

c) CH3COOH (Acetic acid): Acetic acid is a weak acid and may not react as readily with calcium carbonate to produce carbon dioxide. The reaction with acetic acid is slower and less efficient compared to strong acids like HCl and H2SO4.

d) HCOOH (Formic acid): Formic acid is also a weak acid and may not react as readily with calcium carbonate to produce carbon dioxide. The reaction with formic acid is slower and less efficient compared to strong acids like HCl and H2SO4.

Based on the reactivity of the acids, options a) HCl and b) H2SO4 are the most likely candidates for the solution that reacts with crushed egg shells to produce carbon dioxide gas.

In conclusion, the solution that reacts with crushed egg shells to produce carbon dioxide gas most likely contains either hydrochloric acid (HCl) or sulfuric acid (H2SO4). These strong acids readily react with the calcium carbonate in the egg shells, releasing carbon dioxide gas as a byproduct.
