Answer:
A standard test for the presence of carbon dioxide is its reaction with limewater (a saturated water solution of calcium hydroxide) to form a milky-white precipitate of calcium hydroxide.
With valency 4 carbon is able to attain noble gas configuration by sharing its four valence electrons with other elements.
