I have some questions about acetone peroxide.

Example: We want to make acetone peroxide from : acetone , hydrogen peroxide 30% and Sulfuric acid 98%

What causes the conversion of acetone peroxide to trimer or dimer or monomer?

Does temperature affect?

Concentration of hydrogen peroxide?

Type of catalyst?

How to make acetone peroxide trimer?

How to make acetone peroxide dimer?

Please tell me
Calcium sulfate dihydrate, also known as gypsum, is produce when sulfuric acids reacts with calcium carbonate. A limestoon found in the mountaon of magnolia contains 94% CaCO3, 5% MgCO3 and the rest are unreactive spieces called lacrima. Determine of the amount of gypsum produced weight of sulfuric acid sufuric acid used, and the amount of gas formed if 4,500kg of limestone completely reacts with sulfuric acid

Total no of electrons in Cr24 with m= 0
I need help for the following problem:
A solution of VO2Cl 0.01M in 0.1 M HCl is saturated with hydrogen gas at a pressure of 1 atm. Calculate ph and composition of the solution when equilibrium is reached, knowing that:
VO2 + / VO ++ E ° = +1,000 V
VO ++ / V +++ E ° = + 0.337 V
V +++ / V ++ E ° = -0.255 V
Calculate E for the titration of 50.00 mL of 0.100 M Ag+ when 25.00 mL of 0.150 M Cl−
is added. Silver wire is the indicator electrode and the saturated Ag-AgCl electrode is the
reference electrode. E = 0.197 V for the saturated Ag-AgCl electrode,E = 0.7993 V and Ksp =
1.8 × 10−8 for AgCl.

Answer: 0.497 V
