Solution Steps

Step 1: Analyze the provided text

The provided text shows that 5 out of 6 questions were answered correctly. The current question, number 7, is unanswered and pertains to bases, salts, and earth metals dissolving in water.

Step 2: Evaluate the statement about bases

The statement claims bases are salts and earth metals that dissolve in water. This is incorrect. While some bases are formed from earth metals (e.g., alkali metal hydroxides), not all bases are. Additionally, salts and bases are distinct chemical categories. Many bases dissolve in water, but not all.

Step 3: Determine the correct answer

Since the provided statement is false, the correct answer is not to select the checkbox. The "I don't know" option is also incorrect. The user should have selected "False" (not shown in the image).

Final Answer

The statement is false. Bases are not defined as salts and earth metals that dissolve in water. While some bases may contain earth metals and dissolve in water, this is not a defining characteristic of all bases.

Consider a diagram in which the variable measured on the y-axis remains constant while the variable measured on the x-axis increases. The graph of these two variables is a horizontal line, a vertical line, a line that has a negative slope, non-existent because the two variables are not related, or a line that has positive slope.
