Magnesium-aluminum alloys are commonly used in aircraft construction. When treated with acid, both metals react to form hydrogen gas, as shown in the unbalanced chemical equations below. A 1.000 g sample of alloy produces 0.107 g of H2 (g) when reacted with excess HCl (aq). What is the percent composition by mass of Al in the alloy? Al (s) + HCl (aq) à AlCl3 (aq) + H2 (g) Mg (s) + HCl (aq) à MgCl2 (aq) + H2 (g)

A materials scientist has created an alloy containing aluminum, copper, and zinc, and wants to determine the percent composition of the alloy. The scientist takes a 12.502 g sample of the alloy and reacts it with concentrated HCI. The reaction converts all of the aluminum and zinc in the alloy to aluminum chloride and zinc chloride in addition to producing hydrogen gas. The copper does not react with the HCI. Upon completion of the reaction, a total of 9.78 L...
