has 2 oxygens for every carbon.

will contribute one of each for every molecule. You then have to have an even multiple of

molecules to not end up with an odd number of oxygens.
So if you take

, you should end up with 2 carbons on the RHS.

then has 4 oxygens. 2 of them are already accounted for, so you just need one

to balance out the reaction.

Answer:
x> y-300/12
Step-by-step explanation
1. Subtract 300 from both sides
2. Divide both sides by -12
3. Switch the sides
The answer is c, or 3b+6!!
12.) This does not follow the rule of conservation because on the reactant side there is one Na and two Cl while the product side only has one Na and Cl. They are not equal and do not have the same number of atoms for the different elements. In the law of conservation matter cannot be created or destroyed and this does not follow the law.
13.) 2Na + Cl2 —> 2NaCl
Put a 2 in front of Na and a 2 in front of NaCl
