1.	What will happen if limewater is passed through co2 gas?
Answer» Thanks There is an exothermic reaction takes place with hissing sound and both of this combined together to form Ca(OH)2 hence the reation is known as combination reation. Carbon dioxide\xa0reacts with\xa0limewater(a solution of calcium hydroxide, Ca(OH)\xa02),\xa0to\xa0form a white precipitate (appears milky) of calcium carbonate, CaCO\xa03. Adding more\xa0carbon dioxideresults in\xa0the\xa0precipitate dissolving\xa0toform a colourless solution of calcium hydrogencarbonate.
