Fractioned Chemical Equations?

Postby DLee_1L » Thu Oct 03, 2019 5:45 pm

So technically, fractioned chemical equations (e.g H2 + 1/2O2 -> H2O) is balanced. But we multiply so that we have whole numbers because it's easier to look at and work with?

From my understanding, yes you are correct. Using whole numbers just makes things easier to use or read for lab experiments or simple calculations.

Yes. So you'd have to multiply that whole chem equation (both sides) by 2 to get rid of the fraction.

Yes, if you were to multiply by 2 to get rid of the fractions it would be correct so long as you multiply the moles of all the reactants and products. Doing so would ensure that the mole ratios remain the same.

Yes, it's better and more practical to change fractional coefficients in chemical equations into whole numbers. With whole number coefficients, you could clearly see mole ratios between reactants and products.

Yes you are correct. Whole numbers make the equation seem a little more sophisticated and easier for chemists to read. Just make sure to multiply both sides of the equation which won't affect the balance if each atom type.
