Terephthalic acid, used in the production of polyester fibers and films, is composed of carbon, hydrogen, and oxygen. When 0. 6943 g of terephthalic acid was subjected to combustion analysis it produced 1. 471 g co2 and 0. 226 g h2o. If its molar mass is between 158 and 167 g/mol, what is its molecular formula?

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
