Copper carbonate hydrate produces 1 mole of water (MW = 18.015 g/mol) was for every mole of solid product (MW = 79.545 g/mol) produced. Given that 3.327 g of product was produced during the reaction, how many grams of water were released as water vapor? (moles = mass/molecular weight).
Write a complete, balanced equation for this double displacement reaction. (Hint: the solid is a composed of Ni+2 ions and hydroxide ions.) Don't write the net ionic equation but rather the complete form with neutrally charged compounds with all of the atoms.
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 me..
