BC Science 10?

what? no!
is one of the question in my chemistry textbook!

Which country are u in? Or, which country's textbook are u using?

But give u the answer 1st.
Balanced equation:
2C2H5OH (l) + 7O2 (g) ----> 4C02 (g) + 6H20 (g)
It obeys the law of conservation of mass because the numbers of atoms in the 2 sides of the equation are the same. It means, nothing is added or disappearing in this chemical reaction.
