Hope thi helps :) and I'd appreciate if you'd mark brainliest because ive been stuck on the same rank for quite a long time :(
A) Potassium
Potassium contains the six chemical elements that make it an alkali metal?
Amount of NH3 = 6.39 mol
Ratio of NH3 : Ratio of product
4 : 10
Hence, amount of product formed = 6.39/4 * 10 = 15.975mol = 16.0mol (3sf)
