Currently in this equation, you have 2 hydrogen atoms and 2 oxygen atoms on the left, and then 2 hydrogen atoms and 1 oxygen atom on the right. To balance, you would need to even out the oxygens, so we can first place a 2 in front of H2O to get:
H2 + O2 -> 2H2O
Now, however, you can see that we have too many hydrogen atoms on the right, so to get the final answer, we add a 2 in front of hydrogen on the left:
2H2 + O2 -> 2H2O
I hope this helps!
Answer:
Explanation:
Hello,
In this case, given the mass of the sample and mass of tin we can compute the mass of oxygen via:
Thus, by using the atomic bas of tin and oxygen we can compute their moles:
Next, we need to divide both moles by the moles of oxygen as those are the smallest in order to compute the subscript in the chemical reaction:
Therefore, empirical formula of the oxide should be:

Explanation:
cannot be present in appreciable concentrations in a solution that is strongly acidic in nature. A weak acid is a complex that consists of hydrogen bound to an anion that does not dissociate well in solution comparing to a strong acid which dissolves completely to an anion. Therefore, cannot be present in appreciable concentrations in a solution that is strongly acidic in nature.
Answer:
2
Explanation:
There are 3 carbons on the right side
there are only two on the left side....you need one more ...so add one more... change the '1' coefficient in front of C to '2'
