Step 1: Define

[RxN - Balanced] 6HCl + Fe₂O₃ → 2FeCl₃ + 3H₂O

[Given] 10.4 mol HCl

Step 2: Identify Conversions

[RxN] 6 mol HCl = 3 mol H₂O

Step 3: Stoichiometry

under a microscope, cancer cells may look very different from normal cells. they often have different sizes and some may be larger than normal while others are smaller. cancer cells are often abnormally shaped and the control centre of the cell (the nucleus) may have an abnormal appearance.

i think? ?

a electronegativity decreases beacuse the size of nucleus is bigger.
