Yes, as limewater is liquid slaked lime if I recall correctly. And if carbon dioxide reacts with limewater, it turns cloudy.
yes
chemical reaction between copper oxide and glucose
A chemical change. CaSO3 is insolube in water.
Chemical equation between the reaction of carbon dioxide and lime water is, CO2 + Ca(OH)2 -------> CaCO3 + H2O
Lime water turns milky when CO2 (carbon dioxide) is passed through it. So to test if a given liquid is lime water, pass CO2 through it, if it turns milky, then it is limewater. You can reverse this chemical reaction by putting vinegar in it.
Lime can be used to start a fire if it is exposed to water. For example, leave a bag of lime outside in the open air. When it rains, the water coming in contact with the lime is able to cause a reaction that starts a fire.If you want the actual chemical equation:CaO + H2O -> Ca(OH)2 OR Calcium Oxide + Water = Calcium Hydroxide
Chemical reaction of lime and dehydrated gypsum with water.

Chemical equation between the reaction of carbon dioxide and lime water is, CO2 + Ca(OH)2 -------> CaCO3 + H2O
The gas yielded from a chamical reaction should be allowed to pass through clean lime water. If the gas is CO2, it turns lime water milky by formation of CaCO3. This is the confirmatory test for CO2 gas
When acids react with carbonates, carbon dioxide is produced. You can test this by waiting for the chemical reaction to take place and then using a bung to insert the gas into lime water!

yes
Lime water absorbs the carbon dioxide gas produced during the reaction
The absorption of water is not a chemical reaction.
yes the air around turns the lime water chalky. It is due to the formation of calcium carbonate from lime water due to its reaction with atmospheric air which contains carbondioxide. the chemical reaction for the phenomenon is as follows Ca(OH)2+co2 =CaCO3+H2O
