Worked Solution & Example Answer:Answer part A or part B - Leaving Cert Chemistry - Question k - 2019
Step 1
Which two substances in the following list make rain water acidic?
Answer
The two substances from the list that make rain water acidic are Carbon Dioxide (CO2) and Sulfur Dioxide (SO2).
Carbon dioxide reacts with water to form carbonic acid, contributing to the acidity of rainwater. Similarly, sulfur dioxide can dissolve in rainwater to form sulfurous acid, which also increases the acidic nature of rain.
Step 2
Which two metals in the following list are transition elements?
Answer
The two metals from the list that are transition elements are Iron and Copper.
Iron (Fe) is well-known for its role in various chemical reactions and industrial applications, while Copper (Cu) is also recognized for its excellent conductivity and use in electrical applications. Both of these elements are characterized by their ability to form variable oxidation states and are located in the d-block of the periodic table.
