Ammonia(NH3) rapidly reacts with HCl, making ammonium chloride(NH4Cl). Calculate the number of grams of excess reactant when 3.80g of NH3 reacts with 4.20g of HCl. Chemical equation= NH3+HCl----->NH4Cl
Fundamentals of acids and bases - Water self ionizes to a small extent creating equal concentrations of hydronium and hydroxide ions. Find the molar concentration of these ions in water at 25 o C?
The label on a tank of gas of unknown origin had been lost. To determine its identity (molecular weight) a certain volume of it took 76.32 seconds to effuse through a porous partition. Under identical conditions HCN effused through the hole in 59...
Suppose that 100.0 mL of a 0.120 M solution of magnesium chloride is mixed with 100.0 mL of .210M sodium hydroxide. Assume that the volumes are additive (which is only approx correct) and calculate the molarity of the chloride ion in the final sol..
