Copper is reacted with H2SO4 acid to form Copper (I) Sulfate. Hydrogen gas is produced during this reaction. If 5 liters of the acid solution which has 0.2 M, was added to the stochiomateric amount (i.e. the theoretical amount precisely) of the metal,
Calculate:
1-The mass of the metal reacted.
2-The mass of Copper (I) Sulfate produced.
3-The mass of hydrogen gas produced.

Silver has an average atomic mass of 107.87 u. If 48.18% of Ag exists as Ag-109 (108.9047 u), what is the identity and the atomic mass of the other isotope?
if the solubility of agno3 at 40oc is 211 g per 100 g of water what mass of this solute can be dissolved in 350 g of
A buffer is prepared by mixing 453 mL of 0.143 M HCl with 983 mL of 0.848 M ammonia (NH3). Given that the Kb of NH3 is 1.8 x 10-5, calculate the pH of the solution.
Two isotopic compounds are produced in the synthesis of a new therapeutic drug which must be separated by repeated chromatography cycles. In each cycle, the solution containing both compounds must pass through a chromatography column
