Simple 1 Step Stoichiometry 1. Using the following equation:
2NaOH+H2SO4 + 2 H2O + Na2SO4
a.
How many moles of Na2SO4 can be made with 8.55 mol of H2SO4?
b. How many moles of H2O can be made from 3.06 mol of H2SO4?

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.
