Consider the following intermediate chemical equations.
2h2(g) + o2(g) → 2h2o(1)
h2(g)+f2(g) → 2hf(g)
in the final chemical equation, hf and o2 are the products that are formed through the reaction between h20 and f2. before
you can add these intermediate chemical equations, you need to alter them by multiplying the
second equation by 2 and reversing the first equation.
first equation by 2 and reversing it.
first equation by (1/2) and reversing the second equation.
