Question 3 6 pts Examine the balanced net ionic equations for the metals that reacted anywhere in this experiment. Select all of the true statements from the list below. One or more answers are true and you will receive negative points for incorrect answers. The sum of the charges for the reactants equals the sum of the charges for the products. One of the products of the reaction is always hydrogen gas. The metal always loses electrons in the reaction....

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

Question 22 5 pts Which of the following statements about the quantum- mechanical model of atoms is true? Not only did the Bohr model correctly describe the hydrogen atom and its line spectra, but it also perfectly described more complicated multi-electron atoms.
