Using the following balanced reaction , how many mol of water are formed if 5.20 mol of Fe (OH)3 react completely? 2Fe (OH)3 +3H2SO4 --> 6H2O +Fe2(SO4)3
Calculate the number of moles in each of the following: a) 85.2 g of Ni, b) 144 g of K, c) 6.4 g of H2O, d) 308 g of BaSO4, e) 252.8 g of fructose C6H12O6
The total precipitate was dissolved in HCl + HNO3. When the solution thus formed was treated with excess NaOH followed by H2O2, a colorless solution and a reddish brown precipitate were formed. The precipitate was found to be soluble in HCl, H2SO4..
What is the molecular formula for the compound containing 30.4% nitrogen and 69.6% oxygen by mass and having a molar mass of 92.0 g?
Two solutions of an unknown slightly soluble salt, A(OH)2, were allowed to equilibriate- one at 25 degrees C, the other at 80 degrees C. A 15 mL aliquot of each solution is tiotrated with .200 M HCl. 8 mL of the acid is required to reach the endpo..
