Carbon dioxide is also known as CO2. It is composed of two oxygen atoms bonded to a single carbon atom. At standard temperatures, CO2 is in a gas form. Some people make CO2 for making their vegetable gardens more productive. Plants use CO2 in the photosy
Scientists use sophisticated instruments to measure concentrations of harmful substances in the air, but it's tough to say exactly what percentage of air pollution comes from cars. This makes sense, because many other human activities contribute to air pollution as well. In fact, the production of...
