Hey man its difference in temperature
Answer:
1.) 2H2 + O2 ---> 2H2O
2.) CH4 + 4Cl2 ---> CCl4 + 4HCl
Explanation:
In order to balance the equation, you have to make sure there are the same amount of each element on both sides.
Ex (#1). By adding the coefficients infront of H2 and H20, You now have 4 hydrogen's and 2 oxygens on the left side as well as 4 hydrogens and 2 oxygens on the right side.
Sorry if that's confusing, but hope this helps! :)
