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

(a) 485 x 200 mg = 97000 mg of ibuprofen in the bottle
97000 mg x (1g/1000mg) = 97g of ibuprofen in the bottle
97g (1 mol/ 206.5gC13H18O2) = 0.46973 moles of ibuprofen in the bottle
(b) 0.46973 mol C13H18O2 (6.022 x 10^23 molecules/1mol) = 2.8287 x 10^23 molecules of ibuprofen in the bottle

Answer:
Protons carry a positive electrical charge and they alone determine the charge of the nucleus. Adding or removing protons from the nucleus changes the charge of the nucleus and changes that atom's atomic number. For example, adding a proton to the nucleus of an atom of hydrogen creates an atom of helium.
i hope this helps!
