Interpretation:
The correct statement regarding the tap water needs to be determined.
Concept introduction:
A mixture consists of two or more substances which can be separated by different methods. A compound is a combination of two or more elements in fixed ratio held together by

Answer to Problem 13STP
Student A is correct.
Explanation of Solution
Pure water is a compound containing oxygen and hydrogen in fixed ratio. Tap water consists of many impurities which can be separated by filtration method. So, the tap water is a mixture not a compound. So, student A is correct.
Tap water is not a compound because it consists of many impurities. In a compound, two or more elements in fixed ratio held together by chemical bonds.

- For each scenario below, select the color of the solution using the indicator thymol blue during the titration. When you first add indicator to your Na2CO3solution, the solution is basic (pH ~10), and the color is ["", "", "", "", ""] . At the equivalence point for the titration, the moles of added HCl are equal to the moles of Na2CO3. One drop (or less!) past this is called the endpoint. The added HCl begins to titrate the thymol blue indicator itself. At the endpoint, the indicator color is ["", "", "", "", ""] . When you weren't paying attention and added too much HCl (~12 mL extra), the color is ["", "", "", "", ""] . When you really weren't paying attention and reached the second equivalence point of Na2CO3, the color isarrow_forwardThe following reaction is run in which the initial conditions include only methane (CH4) at a concentration of0.115 M.
