How can limewater be made from calcium carbonate?
Limewater can be made by adding calcium carbonate (CaCO3) to water to produce calcium hydroxide (Ca(OH)2). The chemical reaction is CaCO3 + H2O -> Ca(OH)2 + CO2. The resulting solution is limewater, which is commonly used in various chemical tests.
CH4 plus O2 equals H20 plus?
The chemical reaction is: CH4 + 2O2 --> 2H2O + CO2 CO2 is the carbon dioxide.
Balanced equation carbon dioxide limewater?
The balanced equation for the reaction between carbon dioxide and limewater (calcium hydroxide) is: Ca(OH)2 (aq) + CO2 (g) -> CaCO3 (s) + H2O (l) This reaction forms a white precipitate of calcium carbonate and water.
What colour would Carbon dioxide change limewater to?
Carbon dioxide would turn limewater milky white due to the formation of calcium carbonate when it reacts with the calcium hydroxide present in the limewater.
What is the equation for limewater and co2?
Carbon dioxide(CO2) + Lime Water[Ca(OH)2] → Calcium Carbonate(CaC03) + Water(H2O)
Does limewater absorb CO2?
Yes, limewater (calcium hydroxide solution) reacts with CO2 in the air to form insoluble calcium carbonate, causing the limewater to turn milky or cloudy. This reaction is often used as a test for the presence of CO2.
When CO2 mixes with limewater how do you know a chemical reaction took place?
When CO2 reacts with limewater (calcium hydroxide), the solution turns milky due to the formation of calcium carbonate, which is insoluble and precipitates out. This indicates a chemical reaction has taken place as a new substance with different properties has formed.
Why does limewater turn clear when you continue blowing into it after it has turn chalky?
Because there is an excessive amount of CO2, causing another chemical reaction to take place.
How can limewater be made from calcium carbonate?

If a plant is put into limewater in a testube which is sealed and left overnight Will the limewater become very chalky?
Of cousethe plant sets off CO2 which reacts with ca(oh)2 exists in limewater engender caco3so the limewater will become chalky
CH4 plus O2 equals H20 plus?
The chemical reaction is: CH4 + 2O2 --> 2H2O + CO2 CO2 is the carbon dioxide.
Balanced equation carbon dioxide limewater?
The balanced equation for the reaction between carbon dioxide and limewater (calcium hydroxide) is: Ca(OH)2 (aq) + CO2 (g) -> CaCO3 (s) + H2O (l) This reaction forms a white precipitate of calcium carbonate and water.
Is CO2 plus 6H2O a chemical or physical reaction?
CO2 reacts with H2O in one molar ratio forming the carbonic acid . one CO2 molecule can not react with 6 water molecules......
What colour would Carbon dioxide change limewater to?
Carbon dioxide would turn limewater milky white due to the formation of calcium carbonate when it reacts with the calcium hydroxide present in the limewater.
What is the equation for limewater and co2?
Carbon dioxide(CO2) + Lime Water[Ca(OH)2] → Calcium Carbonate(CaC03) + Water(H2O)
How do you test carbondixoide gas?
Use limewater (saturated calcium hydroxide solution). When you bubble CO2 through the limewater, it reacts to form calcium carbonate which makes it visibly cloudy. Ca(OH)2 (aq) + CO2 (g) → CaCO3 (s) + H2O (l)
In a chemical equation what are the reactants and products?
Reactants are the substances that are present at the start of a chemical reaction and are consumed during the reaction. Products are the substances that are formed as a result of the chemical reaction.
