Part A Which one of these statements about formal charge is true? O To draw the best Lewis structure, you should minimize formal charge. Formal charge is used in calculating the dipole moment of a diatomic molecule. Formal charge takes into account the different electronegativities of the atoms in a molecule. Formal charge is the same as oxidation number Formal charge is most useful for ionic compounds. Previous Answers Request Answer Submit X Incorrect; Try Again; 5 attempts remaining Feedhack

Can you help me in this question? Thanks all.
Part A Two workers pull horizontally on a heavy box, but one pulls twice as hard as the other. The larger pull is directed at 25.0° west of north, and the resultant of these two pulls is 470.0 N directly northward. Use vector components to find the magnitude of each of these pulls. Assume that the smaller pull has a component directed to the north Enter your answers numerically separated by...
