Law of Conservation of Energy says that we can't create or destroy Energy and the Law of Conservation of Matter says we can't create or destroy Atoms, so if you are walking behind

you've gain mass?? And does that mean that farting can cause you to lose mass/"weight"??

The covalent compound acetylene, which is the fuel of the oxyacetylene torch used by welders, has the molecular formula c2h2. the covalent compound benzene, a commercial solvent, has the molecular formula c6h6 each of these covalent compounds contains carbon and hydrogen atoms in a one-to-one ratio. would it be correct to write the chemical formulas of each as ch? explain.
