Transcript of Balancing Equations

product Hydrogen (2)
Oxygen (2) Here is how to Balance a
Chemical equation Step 1 Step 2 Final Step Final Equation Lets do this H2 + O2 --> H2O Now the Final step How to Balance
Chemical Equations by Jasmine and Asia Now lets List and number all the elements It's not balanced yet :c First lets get a problem :D H2 + O2 -> H2O H2 + O2 -> H2O >now to balance it
since there is 2 oxygen on the left there needs to be 2 on the right..
> So add a coefficient of 2 H2 + O2 --> (2x) H2O
= H2 + O2 --> (2)H2O Hydrogen (2)
Oxygen (1) H2 + O2 --> H2O (2)H2 + O2 --> (2)H2O > To make this even we must add to hydrogen. To get it to 4 like on the right we must add a coefficient of 2 to hydrogen (2)H2 + O2 --> (2)H2O 2H2 + O2 --> 2H2O why yes those are ugly colors dont judge GOOD JOB! Now you can balance equations! >Now Recount H2 + O2 --> (2)H2O Hydrogen - 2
Oxygen - 2 Hydrogen - 4
Oxygen - 2 reactant
