    Correct Answer

    Explanation
    Lemon juice has a pH of 3, making it acidic. The pH scale ranges from 0 to 14, with 0 being the most acidic and 14 being the most alkaline. A pH of 3 indicates that lemon juice is highly acidic, which is why it has a sour taste. The acidity of lemon juice is due to the presence of citric acid, which gives it its characteristic flavor and pH level.

    Explanation
    The bigger the splatter, the less energy was used to make it. This implies that a smaller amount of energy was required to create a larger splatter.
