1) What volume of 2.25M H2SO4 should be diluted with water to form a 1.25L of 1.50M acid?
2) What is the concentration of the original solution if 450 mL; a certain solution is diluted in 750 mL water to form 2.0L of 1.50M HCl?
the reaction of NH3 and O2 forms NO and water. the NO can be used to convert P4 to P4O6, forming N2 in the process. the P4O6 can be treated with water to form H3PO3, which forms PH3 and H3PO4 when heated. how many grams of NH3 are needed to produce 20.44 g of PH3?
