write a balanced equation for:Gaseous carbon dioxide and liquid water react to produce aqueous glucose (C6H12O6) and oxygen gas.

I try but everytime i change the coefficient it makes the other elements unbalanced.

the starting formula i got was:

CO2(g) + H2O(l) -> C6H12O6(aq) + O(g)

what are the coeficcients and how did u get it? thanks

You make the whole process harder when you write O(g). It's O2 gas. See if that doesn't make everything easier.

so what i have so far is:

6-CO2(g) + 12- H2O(l) -> 1-C6H12O6(aq) + 6- O2(g)

it said all the coefficients were correct except the 12 in front of the H20

how is that wrong?

Count it up. You have 24 H atoms on the left and 12 on the right so it isn't balanced. You also have 24 O atoms on the left and 18 on the right. O doesn't balance either. (In other words, only the C balances). Two suggestions.

a. don't use dashes (-) between the coefficient and the substance, and
b. try a 6 H2O. That will take care of the problems with BOTH H and O.

thanks! i didn't see the 2 after the H

To balance the equation, we need to ensure that the number of atoms of each element is equal on both sides of the equation. Let's go through step by step:

1. Start with carbon:
On the reactant side, we have one carbon atom in CO2, while on the product side, we have six carbon atoms in C6H12O6. Therefore, we need to multiply CO2 by 6 on the reactant side:
6 CO2(g) + H2O(l) -> C6H12O6(aq) + O(g)

2. Move on to hydrogen:
On the reactant side, there are two hydrogen atoms in H2O, while on the product side, there are twelve hydrogen atoms in C6H12O6. We need to balance the hydrogen, so we multiply H2O by 6 on the reactant side:
6 CO2(g) + 6 H2O(l) -> C6H12O6(aq) + O(g)

3. Next, look at oxygen:
On the reactant side, we have 2 oxygen atoms in CO2 and 6 oxygen atoms in H2O, giving us a total of 8 oxygen atoms. On the product side, we have 6 oxygen atoms in C6H12O6 and 1 oxygen atom as a product. To balance the oxygen, we need to multiply O(g) by 7 on the reactant side:
6 CO2(g) + 6 H2O(l) -> C6H12O6(aq) + 7 O(g)

Now, the equation is balanced with respect to carbon, hydrogen, and oxygen. The final balanced equation is:
6 CO2(g) + 6 H2O(l) -> C6H12O6(aq) + 7 O2(g)

Keep in mind that oxygen gas (O2) is produced.
