Chemical Equation Balancer, Needs Improvement
Written by WTJ on March 25, 2008 – 9:33 am -Stumbled this Chemical Equation Balancer and I thought it will eases chemistry students’ life. But…
2H2 + O2 –> 2H2O
That is the simplest and yet the balancer can’t do it. It can only do those equations given in the examples.
H2O is the water equation (just in case you don’t know). Some of you might wonder why the chemical equation to form a water molecule is 2H2 + O2 –> 2H2O.
The fact is, in nature, both hydrogen (H) and oxygen (O) exist in diatomic molecules, which also means each hydrogen molecule is consisted of 2 hydrogen atoms. In order to form water,
H2 + O2 –> H2O
However, you can see that the above equation is not balance. The sum of H2 and O2 should be H2O2, but we want H2O. We need to do some simple maths to balance the equation. All we need to do is adding a 2 in front of H2 and a 2 in front of H2O.
2H2 + O2 –> 2H2O
The 2 in front of the 2H2 means there are 2 hydrogen molecules ( H2 +H2 ). So,
H2 + H2 + O2 –> H2O + H2O
2H2 + O2 –> 2H2O
