How many liters of O2 can be made from 342 g of H2O2?The density of H2O2 is 1.463g/mL and the density of O2 is 1.428 g/L. How many liters of O2 can be made from 55.0 mL of H2O2? How many liters of O2 will form if 22.5 g H2O2 react?
After treating an antacid with 5.00 ml of .1065 M NaOH, the untreated acid was diluted to exactly 250 mL with distilled water in a volumetric flask. 25.00 mL of that diluted acid required 17.03 mL of the same NaOH solution to neutralize it. Calcul..
If a solution contains 0.01M Ca^2+, 0.01 M Zn^2+, and 0.01 M Ni^2+ ions and you want to separate them using aqueous (NH4)2C2O2, which ion will precipitate first as an ozalate, CaC2O4, ZnC2O4, or NiC2O4
What are these 3 techniques? Explain in detail how each technique is used and what information you receive from using them?
Zinc metal can be obtained from zinc oxide (ZnO) by reacting the oxide with the element carbon. The products of the reaction are Zn and CO2.
