Fractions as Coefficients
Is it possible to have fractions as coefficients when balancing chemical reactions? I came across a problem where I had 2/3 as a coefficient, and I wasn't sure as to whether that's acceptable or not?
Thank you!
Thank you!

Re: Fractions as Coefficients
Hi!
When you come across fractional coefficients in balancing, it's preferred to multiply every coefficient by the number in the denominator(in your case, 3) so that there are no fractional coefficients. This most usually happens with oxygen in combustion reactions, where sometimes you have to double every coefficient because oxygen has a fractional coefficient.
Hope this helps ^^

Hello!
I believe if we have fraction as a coefficient, we need to multiply every coefficient by a denominator to create whole numbers.
Hope this helps!

Yes, it's possible to have fractions as coefficients, but you would just need to multiply that fraction out so that you get whole numbers. The result would be the final acceptable answer in a balanced chemical equation.

Yes, it's possible to have fractions as coefficients! However, it's preferred that you have whole numbers as coefficients. At that point, you will have to convert the fractions into whole numbers by finding the common denominator and multiplying it out.

Re: Fractions as Coefficients
When you have fractions as coefficients, you have to multiply the entire equation so that all coefficients are whole numbers.

Re: Fractions as Coefficients
You can't really have a fraction as a coefficient. If you end up with one, you have to multiply every coefficient in the equation by the least common multiple of all the denominators to get the lowest possible whole number for the coefficients.

Hi! Fractions as coefficients are not really possible, so it is best to convert the fraction to a whole number by multiplying the fraction by the number in the denominator. Remember to multiply all the coefficients in the equation as well since you have to increase all the ratios to keep the equation balanced.

Hi! I would multiple the whole reaction by the denominator, in this case, 3. It would make all the coefficients integers which would make it easier if wanting to do more with the equation.

Re: Fractions as Coefficients
Typically in balancing equations, you would want to get rid of the the fractions. As others have explained, you can accomplish this by multiplying the whole equation by the denominator of the fraction of the given molecule.

Fractions as coefficients are usually not acceptable so just multiply the all the coefficients by the denominator of the fractional coefficient so they are all whole numbers. Hope this helps!

Re: Fractions as Coefficients
We must have whole numbers as our stoichiometric coefficients, so I'd find a common denominator and multiply to get whole numbers.

Hi! If you end up getting a fraction, you'd probably have to multiply all the coefficients by the denominator so that you get a whole number and maintain your balanced reaction

Re: Fractions as Coefficients
In balanced equations, you would typically want a whole number as the coefficient so if you do have a fraction as a coefficient, multiplying by a value that will give you all whole number coefficients.

Hi!
When coefficients are fractions, multiplying the bottom of the fraction through to every coefficient is helpful to achieve whole numbers (assuming that all of the other coefficients may be divided by the denominator in the fractional coefficient). Hope this helps!!
