Your class wanted to verify a certain property of acids over lime water. Use this information to answer questions 1 and 2.

Here are the answers to the questions:

Question 1: The property of acids being tested is the ability to B. Produce carbon dioxide when it reacts with carbonate compound Lime water ($\text{Ca(OH)}_2$) is used to test for the presence of carbon dioxide ($\text{CO}_2$). Acids react with carbonate compounds to produce $\text{CO}_2$ gas.

Question 2: What observation will be made in the experiment with lime water? A. A clear lime water turns milky indicating the production of $\text{CO}_2$ gas When carbon dioxide gas is bubbled through clear lime water, it reacts to form insoluble calcium carbonate ($\text{CaCO}_3$), which appears as a white precipitate, making the solution milky.

Question 8: Which of the following statement is true about binary compounds? A. consist of only two elements A binary compound is defined as a chemical compound that contains exactly two different elements.
