Magnesium - aluminium alloys are widely used in circraft
construction. one particular alloy contains 70.0% al and
30.0% mg. how many grams of halg) are produced in
the reaction of 0.710g samples of this alloy with excess
heleg?
2 alig + 6hcl(aq) – 2 acc( 3 lags + 3h2 lg)
mg(s) + 2hcl(aq) - mg cl2 lag) + h2 lg)

The characteristics of two different types of reactions are shown below: reaction a: electrons are gained by the atoms of an element. reaction b: protons are lost by the atom of an element. which statement is true about the atoms of the elements that participate in the two reactions? their identity changes in both reaction a and reaction b. their identity changes in reaction a but not in reaction b. their identity changes in reaction b but not in reaction a. their identity remains the same in both reaction a and reaction b.
