Chemistry:
Which of these two chemicals is the limiting reactant?
Grams are not present in the reactant side and I don't know why,
I typed the formula straight off of my homework but I can assume Al
on the reactant side have the mass
2Al($)+2KOH(aq) +4H2SO4(aq)+22H20(1) +2K AHSO4)2-12 H20(s)+ 3H2(g).

This question has to do with an alum synthesis experiment from aluminum, KOH, and H2SO4. The overall reaction is given in equation (1-1): (1-1) 2Al(s) + 2KOH(aq) + 22H2O(l) + 4H2SO4(aq) ---> 2KAl(SO4)2.12H2O(s) + 3H2(g) Note: we used 0.045 moles of H2SO4 and 0.0175 moles of KOH in the experiment. Question 1: Given that KAl(OH)4 was limiting, how many moles of H2SO4 were actually used to form the maximum possible amount of KAl(SO4)2 (Hint: Moles of Al used in this...

how
would i write an equation explaining how i confirmed that sulfate
was present in my product. in order to confirm this we added BaCl
to our product
equation: 2Al(s) + 2KOH(aq) + 4H2sO4 + 22H2O --> 2KAl(SO4)2
• 12H2O + 3H2(g)
how would i do this?

Synthesis of Alum (Potassium Aluminum Sulfate) from Aluminum Aluminum cans can be recycled to make potassium aluminum sulfate dodecahydrate, KAK(SO)12H20, which is abbreviated to "alum". The 12 waters are part of the overall formula. Alum can be used to make dyes, printing fabrics, making paper, adhesives, pickling of food and vets use it to induce a dog to throw up. x 1 rxn 2 run 3 The following are the four reactions that lead to alum: Al(s) + 2 KOH...
