Carbon dioxide (CO2 gas ) react with lime water (Ca(OH)2) in a chemical reaction to produce limestone or marble or chalk(CaCO3) and water(H2O).
EQUATION
CO2+Ca(OH)2=CaCO3+H2O.
Calcium Oxide (CaO) in the calcium hydroxide (Ca(OH)2) compoud breaks to react with the carbon dioxide (CO2) to produce calcium carbonate (CaCO3) and water (H2O) is produced from the remaining atoms.
EQUATION
CaO+CO2 = CaCO3

What happens if vinegar and limewater were mixed together?
When vinegar and limewater are mixed together, a reaction would occur between the acetic acid in the vinegar and the calcium hydroxide in the limewater. This reaction would produce calcium acetate, water, and carbon dioxide gas. The carbon dioxide gas would be seen as bubbles forming in the mixture.
Can carbon dioxide and oxygen be mixed?
Yes, carbon dioxide and oxygen can be mixed together. In fact, the air we breathe is a mixture of various gases, including carbon dioxide and oxygen. However, the optimal ratio for breathing is about 21% oxygen and less than 1% carbon dioxide.
What happens when citric acid and sodium hydrogencarbonate are added together?
When citric acid and sodium hydrogen carbonate are mixed together, a chemical reaction occurs that produces carbon dioxide gas. This reaction results in fizzing or effervescence, as the carbon dioxide gas is released.
How do you test for hydrogen gas when zinc and hydrochloric acid are mixed?
As metal carbonates react with acid, a neutralisation reaction happens. Salt, water, and carbon dioxide are produced. This can be expressed in the following general equation:metal carbonate + acid → salt + water + carbon dioxide To test for carbon dioxide the gas can be bubbled through limewater. Carbon dioxide will dissolve slightly in water to make a weak acid (carbonic acid). Another neutralisation reaction then happens between the limewater (calcium hydroxide) and the carbonic acid. This makes the limewater turn milky, which is the positive result for carbon dioxide.visit : ask-astrologer.blogspot.com for more on this
What gas is produced when calcium carbonate and hydrochloric acid is mixed?
Carbon dioxide gas is produced when calcium carbonate and hydrochloric acid are mixed. This reaction occurs as the acid reacts with the calcium carbonate, releasing carbon dioxide gas as a byproduct.
What happens if vinegar and limewater were mixed together?
When vinegar and limewater are mixed together, a reaction would occur between the acetic acid in the vinegar and the calcium hydroxide in the limewater. This reaction would produce calcium acetate, water, and carbon dioxide gas. The carbon dioxide gas would be seen as bubbles forming in the mixture.
Carbon dioxide and lime water?
CaCO3 (s) + H2O(l) CaCO3 is a white solid that appears cloudy in solution Limewater is also used in the chemical test for carbon dioxide. The chemical test is if carbon dioxide is mixed with limewater it then clouds. If this happens then the gas will be carbon dioxide.
Can carbon dioxide and oxygen be mixed?
Yes, carbon dioxide and oxygen can be mixed together. In fact, the air we breathe is a mixture of various gases, including carbon dioxide and oxygen. However, the optimal ratio for breathing is about 21% oxygen and less than 1% carbon dioxide.
Can carbon dioxide be mixed helium?
Yes, carbon dioxide and helium can be mixed together. However, it is important to note that breathing in a mixture with high levels of carbon dioxide can be harmful, so caution should be taken when handling such mixtures.
Is carbon dioxide a mixed substance?
Carbon dioxide is a compound of two gases; Carbon and Oxygen. Therefore it is not a mixture, or mixed substance.
Which gas turn lime water milky?
The gas that turns lime water milky is carbon dioxide. When carbon dioxide is passed through lime water, it reacts to form calcium carbonate, which is insoluble and gives the solution a milky appearance.
What is an example of a gas and liquid mixed together?
An example of a gas and liquid mixed together is carbonated water, where carbon dioxide gas is dissolved in liquid water to create fizzy bubbles.
Why does carbon dioxide affect lime water?
CO2 + Ca(OH)2 -> CaCO3 + H2OCarbon dioxide reacts with calcium hydroxide (lime water) to form calcium carbonate and water. Calcium carbonate is insoluble therefore exist in the form of a white precipitate which turns the solution cloudy.
What happens when citric acid and sodium hydrogencarbonate are added together?
When citric acid and sodium hydrogen carbonate are mixed together, a chemical reaction occurs that produces carbon dioxide gas. This reaction results in fizzing or effervescence, as the carbon dioxide gas is released.
What gas is created when baking soda and vineger are mixed together?
Carbon dioxide gas, called 'fizz' in cola and bubble water.
Is carbon dioxide released when sugar and vinegar are mixed?
Sugar and vinegar do not react on mixing - no carbon dioxide is produced.
What is mixed with water to make it sparkling'?
Carbon dioxide.
