Reactivity of Metals with Acids

The video tutorial discusses the reactions of metals with acids, focusing on the role of Table J in determining reactivity. It explains that metals above hydrogen on Table J react spontaneously with acids, producing hydrogen gas and a salt. The tutorial provides examples of reactions, including balancing equations, and offers practice problems to reinforce learning. It concludes with a Regents question on reaction spontaneity, emphasizing the importance of Table J in predicting reactions.

Which metals on Table J will spontaneously react with acids?

• All metals

• Only copper, silver, and gold

• Metals above hydrogen

• Metals below hydrogen

What are the typical products when a metal reacts with an acid?

• Water and salt

• Hydrogen gas and salt

• Oxygen gas and salt

• Carbon dioxide and salt

In the reaction of hydrochloric acid with zinc, what is the correct formula for zinc chloride?

• Zn2Cl2

• Zn2Cl

• ZnCl2

• ZnCl

What is the balanced equation for the reaction of sulfuric acid with calcium?

• H2SO4 + Ca → H2 + CaSO4

• H2SO4 + Ca → H2O + CaSO4

• H2SO4 + Ca → H2 + CaSO3

• H2SO4 + Ca → H2O + CaSO3

• Iron does not react with acids

• Iron is equally active as hydrogen

If a metal is below hydrogen in Table J, what can be inferred about its reaction with acids?

• It will react spontaneously

• It will react slowly

• It will react explosively

• It will not react
