BALANCING CHEMICAL EQUATIONS: PRACTICE AND REVIEW
From albert.io
Estimated Reading Time 6 mins
- CO2 + H2O → C6H12O6 + O2. The first step is to focus on elements that only appear once on each side of the equation. Here, both carbon and hydrogen fit this requirement.
- SiCl4 + H2O → H4SiO4 + HCl. The only element that occurs more than once on the same side of the equation here is hydrogen, so we can start with any other element.
- Al + HCl → AlCl3 + H2. This problem is a bit tricky, so be careful. Whenever a single atom is alone on either side of the equation, it is easiest to start with that element.
- Na2CO3 + HCl → NaCl + H2O + CO2. Hopefully by this point, balancing equations is becoming easier and you are getting the hang of it. Looking at sodium, we see that it occurs twice on the left, but once on the right.
- C7H6O2 + O2 → CO2 + H2O. We can start balancing this equation by looking at either carbon or hydrogen. Looking at carbon, we see that there are seven atoms on the left and only one on the right.
