Determine mass contribution for the following isotopes of the same element. At the end, tell me the atomic mass of the element using the mass contributions.

Do not forget your units or the question will be marked incorrect.

Isotope 2 amu: 186.956

percent abundance: 62.6%

Atomic Mass of the element ?

Water ionizes by the equation h2o(l)⇌h+(aq)+oh−(aq) the extent of the reaction is small in pure water and dilute aqueous solutions. this reaction creates the following relationship between [h+] and [oh−]: kw=[h+][oh−] keep in mind that, like all equilibrium constants, the value of kw changes with temperature.

Which of the following is true for the actual yield of a reaction? it is always calculated as a ratio. it is the yield from the excess reactant. it is the yield from the limiting reactant. it is always less than the theoretical yield.

‘which reaction would most likely require the use of an inert electrode?
