Skeleton equation to word equation c4h10 (g) ^ + o2 (g) -> co2 (g) ^ + h20 (g) ^ = covalent compound

C4H10 is a saturated hydrocarbon or alkane with the general formula CnH(2n+2). Since n = 4 for C4H10, the prefix is but-, and this compound is butane. The rest of the substances are common compounds: oxygen, carbon dioxide and water, so the word equation is:
butane combusted with oxygen gives carbon dioxide and water vapor

Okay well gravitational energy is matter forced by gravity making energy though the kinetic energy then the electric energy produces electricity from the kinetic energy and the kinetic energy gets its energy from the gravitational energy. was that the answer you wanted or something else?
