Answer & explanation:
To balance a chemical equation, we must make sure that there are equal amounts of each element in the equation on either side.
To balance an equation step-by-step we first start by counting the amount of each element on each side. If they aren't equal, we must make them amounts equal on either side.
After you make sure all the elements are balanced, the net charge on both sides must also be equal.
Answer:
how many it is you should give only one question
Answer:
It is required 0.3 molecules of O2 to produce 0.6 molecules of H2O
Explanation:
The water´s formation reaction is: 2H2 + O2 --> 2H2O
This reaction shows the molecular O2:H2O ratio: 1:2.
Then, if we want to know how many molecules of O2 are required to produce 0.6 of H20, it is necessary calculate as it showed next:
0.6 molecules H2O * (1 molecula O2 / 2 molecules H2O)= 0.3 molecule O2
