Answer
The diagrams show if a metal reacts with the acid by displaying visible signs of a reaction. These signs could include the formation of bubbles or fizzing in the solution, or the disappearance of the metal piece, which indicate the production of hydrogen gas and the formation of a salt.
Explanation
## Step 1: Understanding the questionThe question asks us to explain how the diagrams (not provided) show if a metal reacts with the acid. In a typical reaction between a metal and an acid, there are certain signs that indicate a reaction is taking place. ## Step 2: Identifying signs of a reactionWhen a metal reacts with an acid, it typically produces a salt and hydrogen gas. The production of hydrogen gas can be observed as bubbles or fizzing in the solution. The metal piece may also start to dissolve or disappear. ## Step 3: Formulating the answerBased on the information above, we can conclude that the diagrams would show a reaction between the metal and the acid if there are visible signs such as bubbles, fizzing, or the disappearance of the metal piece.
