Velma and Shaggy are debating on which cleaning solution to use when cleaning the Mystery Machine based on how strong the solution may be. Velma recommends using a 0.25 M NaOH solution with a pH of 13.40.
Shaggy recommends using a 0.025 M NaOH solution with a pH of 12.50.

Who is recommending the stronger cleaning solution, Velma or Shaggy? Why is their recommendation correct?

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.

the correct answer to this question is 2
