When dilute sulphuric acid is added to marble chip reaction starts then stops immediately explain this observation

GPT 3.5
When dilute sulphuric acid is added to marble chips, a reaction takes place between the acid and the calcium carbonate (the main component of marble chips). The reaction produces carbon dioxide gas, water, and calcium sulfate.
The initial fizzing and bubbling that occurs when the acid is added is due to the rapid production of carbon dioxide gas. This gas escapes from the solution, leaving the calcium sulfate product behind. As more and more carbon dioxide gas is released from the reaction, the rate of production of the gas slows down and eventually stops. This is why the reaction appears to stop immediately after it starts.
In reality, the reaction is still occurring, but at a much slower rate. The carbon dioxide gas is still being produced, but it is no longer being released quickly enough to produce visible bubbles. The reaction will continue until all of the calcium carbonate has reacted with the acid and no more gas can be produced.
