Consider the unbalanced equation for the oxidation of butene. C4H8 + 6O2 Right arrow. CO2 + H2O For each molecule of C4H8 that reacts, how many molecules of carbon dioxide and water are produced? two carbon dioxide molecules and two water molecules four carbon dioxide molecules and four water molecules two carbon dioxide molecules and four water molecules four carbon dioxide molecules and two water molecules

You use the atomic number to find out how many protons and neutrons there are in the atom. you use the atomic mass to find out how many protons and electrons there are in the atom. 

Ametal with a large number of free flowing electrons most likely has good conductivity

Are there any options that could alot..

Answer:             1.0  × 10⁻⁵ msolution:                     as we know ph is given as,                                    ph  = -log [h⁺]and,                                    [h⁺]  =  10^-ph    (1)putting value of ph in eq. 1,                                    [h⁺]  =  10⁻⁵                                    [h⁺]  =  1.0  × 10⁻⁵ m
