Use the following BALANCED equation to answer the question: 2 C4H10 + 13O2 → 8 CO2 + 10 H2O what is the mole ratio of C4H10 to carbon dioxide for this equation?

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.

your answer is a. the enthalpy of formation for a pure element in its standard state is always positive.
