The answer is the second one: The total magnification would be 400X.

Explanation for each option:

  1. The total magnification would be 4X. - This is incorrect. The 40X objective lens alone provides a magnification of 40 times, not 4 times.

  2. The total magnification would be 400X. - This is correct. Total magnification is calculated by multiplying the magnification of the objective lens by the magnification of the eyepiece lens. Typically, the eyepiece lens has a magnification of 10X. Therefore, 40X (objective) multiplied by 10X (eyepiece) equals 400X total magnification.

  3. The total magnification would be 40X. - This is incorrect. This option only considers the magnification of the objective lens and does not account for the additional magnification provided by the eyepiece lens.

In summary, the total magnification when using a 40X objective lens with a standard 10X eyepiece is 400X.

All six compounds are acids. Select the statements that are true. (A) H-Cl (B) H-F A and B are binary acids. C and D are carboxylic acids. E and F are carboxylic acids. B is a stronger acid than A because the fluorine atom is more electronegative than the chlorine atom. C is a stronger acid than D because there are more oxygen atoms surrounding the central atom in C than in D. The presence of the chlorine atom in F makes it a stronger acid than E.
