Calcium carbonate works as a mild abrasive that helps to gently scrub away surface stains on various materials, such as teeth or countertops. It also has a slightly alkaline pH that can help break down acidic stains like wine or coffee. Its abrasive nature combined with its alkalinity makes it effective in removing certain types of stains.
What else can I help you with?
When 20g of calcium carbonate are decomposed by heating 8.8g of carbon dioxide are given off. Work out the mass of calcium carbonate that would be required to give 22g of carbon dioxide.?
Using stoichiometry, we can calculate the molar ratio between calcium carbonate and carbon dioxide. When 20g of calcium carbonate decompose to form 8.8g of carbon dioxide, the molar ratio is 1:1. Therefore, to produce 22g of carbon dioxide, you would need the same mass of calcium carbonate, which is 20g.
How do bases, such as calcium carbonate, work in chemical reactions?
Bases like calcium carbonate work in chemical reactions by accepting protons (H) from acids, which helps neutralize the acidity and balance the pH level. This process is known as neutralization and forms water and a salt as products.
Is calcium carbonate a buffer?
Calcium carbonate is not considered a buffer because it is a weak base that can neutralize acids, but it lacks the ability to maintain a stable pH in a solution. Buffers are composed of a weak acid and its conjugate base or a weak base and its conjugate acid, which work together to resist changes in pH.
How effective is vinegar in removing stains from clothes?
Vinegar can be effective in removing some stains from clothes, particularly those caused by substances like coffee or sweat. Its acidic properties can help break down and lift the stain. However, it may not work on all types of stains, so it's best to test it on a small, inconspicuous area first.
How effective is bleaching polyester fabric in removing stains and restoring its original color?
Bleaching polyester fabric can be effective in removing stains and restoring its original color, but it may not work as well as on natural fibers like cotton. It is important to follow the care instructions on the garment to avoid damaging the fabric.
Removing Stains from Carpet?
'Vanish' really does work pretty well!!
What experiment can you do to find out how much calcium carbonate there is in limestone?
To determine the amount of calcium carbonate in limestone, you can perform a titration using hydrochloric acid. By reacting a known mass of limestone with hydrochloric acid, you can measure the volume of acid required to neutralize the calcium carbonate. This information can then be used to calculate the amount of calcium carbonate present in the limestone sample.

How does the limestone cycle work?
Starts off as Calcium Carbonate , when heated the calcium carbonate becomes Calcium Oxide + Carbon Dioxide, the Calcium Oxide then reacts with water to produce Calcium Hydroxide and then when more water is added then filtered it becomes Calcium Hydroxide Solution, C02 is then added to form Calcium Carbonate again [:
Calcium carbonate decomposes into calcium oxide & carbon dioxide Her results:Mass of calcium carbonate before heating = 2.00 g Mass of calcium oxide left after heating = 1.12 g work out the mass of carbon dioxide released during the decomposition?
I am not sure of the answer so can someone help me pls

How effective is baking soda for removing stains on carpet?
Baking soda can be effective for removing some stains on carpet, especially those caused by acidic substances like coffee or wine. It works by absorbing the stain and neutralizing odors. However, it may not work on all types of stains, and professional cleaning may be needed for tougher stains.

Buffers are composed of a weak acid and its conjugate base or a weak base and its conjugate acid, which work together to resist changes in pH.
What can i use to substitute precip. chalk?
You can substitute precipitated chalk with calcium carbonate or powdered limestone, as both provide similar calcium content and are often used in similar applications. If you're looking for a non-calcium alternative, talc or magnesium carbonate can also work, depending on the purpose. For culinary uses, consider using food-grade calcium carbonate if it's for dietary needs. Always ensure that the substitute fits the specific requirements of your project or recipe.
What does anti-calcium do and how does it remove a build up of calcium stains?
I don't believe it does - I think it just prevents stains. I have calcium stains on my pool because I poured powedered shock into the pool over the winter when the water wasn't circulating (don't do that!) -- now I'm grinding them off by hand witha diamond abrasive pad screwed to a long metal pool and it's grueling work. There's no way a checmial would take these off - even a wire brush didn't make a dent. Good luck

How effective is the heat stain remover in removing stubborn stains from surfaces?
The effectiveness of the heat stain remover in removing stubborn stains from surfaces varies depending on the type of stain and surface. It may work well on some stains but not as effectively on others. It is recommended to test the product on a small, inconspicuous area first before using it on the entire surface.
