Iron is manufactured by reducing iron ore in a Blast Furnace. The equation for the reaction is: Fe2O3 (s) + 3C0 (g)
Fe(s) + 3CO2 (g)
How many moles of CO2(g) are produced when one (1) mole of Fe2O3 is reduced?
A. 1
B. 2
C. 3.
D. 5

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.
