How would you balance: H2 + O2 --> H2O? + Example - Socratic
2015年12月6日 · H 2 + O2 → H 2O Notice the imbalance of atoms. On the left side, the reactant side, there are 2 hydrogen atoms and 2 oxygen atoms. On the right side, the product side, there are 2 hydrogen atoms and only 1 oxygen atom. An important thing to remember when balancing equations is that the molecules themselves may not be changed—only their coefficients can. For example, we can change H 2O to ...
How would you balance H2 + O2 = H2O? | Socratic
2015年10月23日 · From the original equation, you first need to write each component separately. H 2 + O2 = H 2O Left side: H = 2 ; O = 2 (number based on the subscript) Right side: H = 2 ; O = 1 (number based on the subscripts; no subscript means that the element is just 1) Notice that the number of H is already balance but the number of O is not.
