A! Oxidize. Hope this helps!
Answer:
2Al(s) + 6HCl(aq) = 2AlCl3(aq) + 3H2(g)
Explanation:
The reaction is a displacement reaction.
The reaction does not commence immediately because the Al(aluminum) has Al2O3 (Aluminum oxide) which protect it from reacting with water.
It takes some time for the HCl (hydrochloric acid) to eat the coating, then the reaction proceed vigorously to produce hydrogen gas bubbles. Generally metals that are above hydrogen in the electrochemical series tend to displace Hydrogen from Hydrochloric acid. The more negative the electrochemical volts the more the tendency to lose electron. Metal above hydrogen have negative evolts while those below have positive evolts
The products and the reactants are the components of the reaction. The equation of phosphoric acid represents the decomposition reaction as it forms oxygen and water. Thus, option a is correct.
<h3>What is a decomposition reaction?</h3>
A decomposition reaction is a chemical breakdown of the reactant into two or more products. The large and complex compound breaks into smaller and simpler molecules.
The following equation, 4 H₃PO₄ → P₄ + 5 O₂ + 6 H₂O is an example of decomposition as phosphoric acid breaks into phosphorus, water, and oxygen molecules.
Therefore, option a. the reaction of phosphoric acid is a decomposition reaction.
