Carbon is an element true or false
WebAnswer: Carbon dioxide. Explanation: Carbon dioxide is a non-polar molecule, while water is a polar molecule. Due to the fact that carbon dioxide’s atoms share electrons equally, it is a non-polar molecule. electrons are equally distributed among the atoms of water, making it a polar material.
