Okonkwo, a central character in Chinua Achebe's novel "Things Fall Apart," meets his demise through suicide. Facing the disintegration of his culture and personal downfall after killing a colonial official, Okonkwo chooses to hang himself, an act considered an abomination by his community. This action contrasts deeply with his earlier life, driven by a fear of appearing weak like his father. Okonkwo's suicide symbolizes the ultimate defeat and despair in the face of the unstoppable forces of colonialism and change that have invaded and begun to dismantle the traditional Igbo way of life he fought so hard to uphold.

To calculate the formula mass of iron oxide, you first need to know the exact chemical formula, which often is Fe2O3 for ferric oxide. The formula mass is calculated by adding the atomic masses of all atoms in the formula. Iron (Fe) has an atomic mass of approximately 55.85 u, and Oxygen (O) has an atomic mass of about 16.00 u. For Fe2O3, the calculation is as follows: (2 * 55.85 u) + (3 * 16.00 u) = 111.7 u + 48.00 u = 159.7 u. Therefore, the formula mass of iron(III) oxide (Fe2O3) is approximately 159.7 u.

In the context of inkjet cartridges, "XL" stands for "Extra Large." This designation indicates that the cartridge contains more ink than the standard (or "normal") version, offering a higher page yield. This means that XL cartridges can print more pages before needing a replacement, making them a cost-effective option for users with high printing demands. While XL cartridges are more expensive upfront, the cost per page typically is lower compared to standard cartridges. Therefore, consumers looking to minimize their long-term printing expenses often opt for XL cartridges, despite the higher initial cost. It's important to ensure your printer is compatible with XL cartridges before making a purchase.
