Many drain cleaners are a mixture of sodium hydroxide and aluminum filings. When these two substances mix in water , they react to produce enough heat to melt the fat in a clogged drain. The bubbles produced are hydrogen gas. The complete reaction occurs in two steps:
step 1:Al(s)+NaOH(aq) —> Al(OH)3(s)+Na(aq)
step 2: Na+(aq)+H2O —> Na2O(s)+H2(g)
a) Classify step 1 of the reaction as: addition, displacement, or decomposition.
b) Is this an endothermic or an exothermic reaction?
c) Balance each equation for each step of the reaction.
