The reaction rate can be determined by observing the rate of disappearance of the reactants (Al and HCl) and also by observing the rate of appearance of the products (AlCl3 and H2)

If you have 9.7 moles of O<sub>2</sub> how many moles of water could you make? C<sub>3</sub>H<sub>8</sub>+ 5O<sub>2</sub> → 3CO<sub>2</sub> + 4H<sub>2</sub>O

Solution:Balanced chemical equation:C3H8 + 5O2 → 3CO2 + 4H2OAccording to the equation above: n(O2)/5 = n(H2O)/4Thus,n(H2O) = 4 × n(O2) / 5 = (4 × 9.7 mol) / 5 = 7.76 moln(H2O) =...

All of the following would be electrolytes in water except a. HC<sub>2</sub>H<sub>3</sub>O<sub>2</sub> b. BCl<sub>3</sub> c. MgCO<sub>3</sub> d. Pb(OH)<sub>2</sub>

The answer is BCl3 (boron trichloride). Boron and chlorine are both nonmetals, so this is a covalent compound hence cannot ionize in water. It is therefore a nonelectrolyte
