When separated from a water solution cuso4 forms a hydrate with 5 water molecules per formula unit. If 36 g of anhydrous cuso4 are dissolved in water, why mass of the hydrate could be recovered from the solution.
A 0.021 mol sample of a weak acid, HX, is dissolved in 575 mL of water and titrated with 0.41 M NaOH. After 29 mL of the NaOH solution has been added, the overall pH = 6.074. Calculate the Ka value for HX.
Consider the combustion of ammonia: 4 NH3(g) + 3 O2(g) 2 N2(g) + 6 H2O(g). If N2 is produced at the rate of 0.63 mol/s, what is the rate of consumption of NH3?
when methane CH4 reacts with oxygen gas O2, water and carbon dioxide are formed. if 25.0 liters of oxygen reacts at 125.0C and 2.00 atm with 22.00L of methane initially
Calculate the molar heat (enthalpy) of combustion for butyric acid.
Dolomite is a mineral consisting of calcium carbonate (CaCO3) and magnesium carbonate (MgCO3). When dolomite is strongly heated, its carbonates decompose to their oxides (CaO and MgO) and carbon dioxide is expelled.
