A chemist titrates 130.0 mL of a 0.2136 M trimethylamine ((CH3N solution with 0.8361 M HNO3 solution at 25 °C. Calculate the pH at equivalence. The pKb of trimethylamine is 4.19. Round your answer to 2 decimal places. Note for advanced students: you may assume the total volume of the solution equals the initial volume plus the volume of HNO3 solution added.

d.) the average kinetic energy of the gas particles is greater in container b because its particles move faster.

"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."

it is the most commonly accepted one

answer: they produce more slow than unicellular organisms.
