When aluminum, al, metal is dipped in an aqueous solution of hydrochloric acid, hcl, hydrogen gas h_2 is produced with the formation of an aluminum chloride, alcl_2, solution. write the balanced chemical equation showing the phase of reactants and products. express your answer as a chemical equation including phases.
2al(s) + 6hcl(aq) rightarrow 2al^3 6cl(aq) + 3h_2(g)

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 leaf is an organ of a typical plant, and the main functions are to complete photosynthesis and allow the plant to exchange gas, just like how we have the respiratory system. leaves have the stomata, which collects maintains co2 and o2 levels. this is necessary for cell metabolism. the leaf also collects sunlight using chloroplasts. succinctly, leaves own a pivotal role in sustaining plant life.
