2) The reaction above shows an simple chemical reaction involving the
combustion of ethane, a fuel, in the presence of oxygen gas to form
water and carbon dioxide. What is the primary source of hydrogen
atoms in the water molecule on the product side?
A)
Hydrogen from the atmosphere reacts with
Carbon atoms recombine with oxygen to form
hydrogen atoms
Hydrogen atoms in methane form new bonds with
oxygen to form water.
Oxygen atoms from the reactant lose protons and
electrons to form hydrogen.
