Acid is added to a beaker containing crushed marble what effect does the stirring this mixture have on the system?
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.
What else can I help you with?
Acid is added to a beaker containing crushed marbles. what effect does stirring the mixture have on 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.
Is a beaker of lake Ontario water a compound?
No. It would be a mixture containing not just the compound water, but dissolved salts and other minerals.
What equipment would you use to add salt to a beaker?
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.
How do you remove sand from a mixture in a beaker?
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.
When you out salt and water together in a beaker you cause them to form a?
A useless mixture is obtained.
Why is a beaker containing sand and water considered a mixture?
Anything containing two separate entities is a mixture. Sand and water is a heterogeneous mixture because it is not the same throughout.
Explain Why a beaker containing sand and water is mixture although sand itself is a pure substance?
Because you mixed sand and water together in the beaker.
Is a beaker of lake Ontario water a compound?
No. It would be a mixture containing not just the compound water, but dissolved salts and other minerals.
How do you mix oil and water?
pouring it into a beaker and permanently stirring it
Which set of materials would be the most appropriate to use in testing the effects of stirring on the dissolving rate of solute?
Stirring rod, beaker, and a timer.
What is the used of stirring rods?
It is used to stir hot chemicals in a beaker or other containers

What you use a beaker for in science?
Containing liquids that are possibly harmful.
When you out salt and water together in a beaker you cause them to form a?
A useless mixture is obtained.
What is the difference between a beaker and a flask?
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.
What laboratory tools are used to containing liquids and substances?
A Flask or Beaker.
