How much faster will neon effuse than krypton, given that the molar mass of krypton is 83.8 grams and that of neon is 20.18 grams?

According to the Graham's law equation, the effusion rate of neon divided by the effusion rate of krypton is equal to the square root of the molar mass of krypton divided by the molar mass of neon. Doing the calculation, you find that neon effuses 2.03 times faster than krypton.

Explanation:

I don't cap. Also good luck! I believe in you!

2fe + 3h2so4 -> fe2(so4)3 + 3h2

it is necessary to balance equations in order to get the proper amount of reactants as well as products in order not to make a miscalculation.

you cannot change the subscripts as that would change the substance itself. for instance, diatomic elements such as h2 only have the subscript two when a gas. another example would be so4, if you were to change the subscript, the element would no longer be sulfate.

we change the coefficients instead as that only changes the number of molecules rather than the substance itself.

hope this !
