Can dissolve limestone when mixed with water?
Limestone can dissolve in water when it is mixed with carbon dioxide, forming carbonic acid. This weak acid reacts with the calcium carbonate in limestone, leading to its dissolution. This process is a key factor in the formation of caves and karst landscapes. Additionally, acidic rainwater can also enhance the dissolution of limestone.
What is the formula of whitewash?
Typically whitewash is powdered lime (lime as in limestone, not the green fruit!) mixed with water.
What is mixed with limestone to make cement?
it is mixed with clay to form cement.
What is the mass of 0.0249 L of limestone?
The mass of limestone will depend on its density. The average density of limestone is around 2.71 grams per cubic centimeter. You can calculate the mass by multiplying the volume (0.0249 L) by the density. Therefore, the mass of 0.0249 L of limestone would be approximately 0.0675 kg.
What would happen if equal amounts of vinegar and limestone were mixed?
When equal amounts of vinegar (acetic acid) and limestone (calcium carbonate) are mixed, a chemical reaction occurs, producing carbon dioxide gas, water, and calcium acetate. This reaction is characterized by the fizzing or bubbling due to the release of carbon dioxide. Over time, the limestone will dissolve as it reacts with the acid, resulting in a solution of calcium acetate and water.
How does sulfuric acid react with limestone?
if limestone is in a solid form it would degrade (hence a loss in mass of the limestone) and carbon dioxide would be given off. if it is in the powdered form the change in mass would not be very obvious and only a loss carbon dioxide would be seen.
What happens to limestone when it is mixed with hydrochloric acid?
When limestone, which is mostly composed of calcium carbonate, is mixed with hydrochloric acid, a chemical reaction occurs. The acid reacts with the calcium carbonate to produce calcium chloride, carbon dioxide gas, and water. This reaction results in the dissolution of the limestone and the release of bubbles of carbon dioxide.
Do you need to know the individual masses of the samples of water and salt in order to measure the change in mass when the two samples are mixed?
No, you do not need to know the individual masses of the samples of water and salt to measure the change in mass when they are mixed. You can simply measure the mass of the mixture before and after mixing to determine the change in mass.
Why is limestone so important?
Limestone, quicklime and slaked lime are all used to neutralise excess acidity - which may be caused by acid rain - in lakes and in soils. Limestone is used as a building material, and to purify iron in blast furnaces. It's also used in the manufacture of glass, and of cement (one of the components of concrete). * Limestone (CaCO3) can be used as a '''building material''' and in the manufacturing of '''iron'''. * '''Glass''' - heated with sand and soda (sodium carbonate). * '''Cement''' - heated with clay in a kiln. ** Concrete - mixed with sand, water and crushed rock ** Mortar - mixed with sand and water * '''Quicklime''' - heated. ** Slaked lime (Calcium Hydroxide Ca(OH)2) - mixed with water *** Lime motar - mixed with water
Why is limestone good for making cement?
Limestone is made up of calcium oxide which is the key ingredient to make cement. The limestone is mixed in with a particular clay to get the cement mixture.
What gave limestone the name limestone?
Limestone is called limestone because it has lime in it from the sea water it if formed in.
Lakes have been acidified by acid rain hno3 and h2so4 can be neutralized by a process called liming in which limestone caco3 is added to the acudified water what mass of limestone in kg would?
To calculate the mass of limestone (CaCO3) needed to neutralize HNO3 and H2SO4 in acidified water, you can use stoichiometry. First, determine the amount of acid in moles. Then, use the balanced chemical equation to find the moles of CaCO3 needed to neutralize the acid. Finally, convert the moles of CaCO3 to mass in kilograms using its molar mass.
