Calculate the maximum amount of moles of AlCl3 that can be produced when 6.82 moles of Al2O3 react with 34.1 moles of HCl according to the following equation: Al2O3(s) + 6HCl(aq) → 2AlCl3(aq) + 3H2O(aq)

Nitrogen (n), phosphorus (p), and potassium (k) are the main nutrients in plant fertilizers. according to an industry convention, the numbers on the label refer to the mass percents of n, p2o5, and k2o, in that order. calculate the n: p: k ratio of a 30: 10: 10 fertilizer in terms of moles of each element, and express it as x: y: 1.0.

Calculate the expected ph values of the buffer systems from the experiments (a,b,c,d), using the henderson- hasselbalch equation, ph-pka+log[a-]/[ha]. use for pka values carbonic acid= 6.37, and acetic acid= 4.75.
