Which of these is the balanced equation for this reaction

Explanation:

A balanced equation is defined as the equation where number of atoms of the reactant equal to the number of atoms of the product.  

This also means that mass of the reactants is equal to the mass of products in a chemical equation.

For example,

Here, number of atoms on reactant side are as follows.

Au = 2S = 3H = 6

Number of atoms on product side are as follows.

Au = 2S = 3H = 6

Hence, the number of atom of reactant side are equal to the number of atoms on product side.

Therefore, the reaction equation is a balanced equation.

Only algae, oak trees, and bermuda grass produce atp by photosynthesis i am almost positive

Atp is is our little "pocket" of energy. of course, if you have too little, then it means you have too little energy, and you'll pass out. the way to not have enough, is to have no energy sources (glucose, fats, proteins). you can't have too many atp molecules. cycles like the krebs cycle produce it, but if you have too much of any substrate (or too little for that matter), the cycle stops and atp is no longer made (it stops until substrate levels are such that the process can go on). in any case, this is unlikely since atp is constantly hydrolyzed and remade, even while you're asleep. you won't have too much. if you have zero, you are dead or dying.
