Answer:
D. All of these.
Explanation:
For an equation to be balanced the number of atoms of each kind in the reactants and the products should be the same.
Then from this equation, CO is a product.
Last, two carbon atoms undergo reaction with the oxygen molecule for complete reaction to occur. Each atom combines with one oxygen atom.
the most free particles are gases, then liquids, solids
The atom that is made up of two protons is He. The number of neutrons is also two. The number of electrons matters in the charge. So to make 10 electrons, we add 8 more. hence, 4/2 He 8-.
