When acid is added to crushed marble, a chemical reaction occurs between the acid and calcium carbonate in the marble, producing carbon dioxide gas, water, and a salt. Stirring the mixture enhances the reaction by increasing the contact between the acid and the marble particles, allowing for more effective dissolution and gas release. This agitation accelerates the reaction rate, leading to a quicker production of bubbles and more vigorous effervescence. Overall, stirring facilitates a more uniform and rapid reaction within the system.
Stirring the mixture of crushed marbles and acid enhances the interaction between the acid and the marble particles, leading to a more uniform distribution of the acid. This increased contact accelerates the reaction, resulting in a faster release of carbon dioxide gas as the acid reacts with the calcium carbonate in the marbles. Overall, stirring improves the efficiency of the reaction and can increase the rate at which the marbles dissolve.
No. It would be a mixture containing not just the compound water, but dissolved salts and other minerals.
You can use a stirring rod or a spatula to add salt to a beaker. Be cautious not to contaminate the salt or the beaker with other substances while doing so.
You can use filtration to separate sand from a mixture in a beaker. Simply pour the mixture through a filter paper in a funnel set over another beaker. The sand will be left behind in the filter paper while the other components of the mixture pass through.
A useless mixture is obtained.
Anything containing two separate entities is a mixture. Sand and water is a heterogeneous mixture because it is not the same throughout.
Because you mixed sand and water together in the beaker.
No. It would be a mixture containing not just the compound water, but dissolved salts and other minerals.

A beaker has a cylindrical shape with a spout for pouring, and is primarily used for stirring, mixing, and heating liquids. A flask typically has a narrow neck and is used for containing and storing liquids without significant evaporation or contamination. Flasks are usually more specialized and precise in their applications compared to beakers.
