Greater mobility in the First World War eventually led to trench warfare because the advancements in military technology, such as machine guns and artillery, made it difficult for soldiers to move freely across open battlefields. As a result, both sides dug trenches to protect themselves from enemy fire. Additionally, the development of barbed wire and the use of chemical weapons further hindered mobility, forcing soldiers to seek protection in the trenches. This shift to static, defensive warfare ultimately led to the prolonged and brutal stalemate of trench warfare. **

The correct name for the compound is lead(II) chloride. The Roman numeral II in parentheses indicates that the lead ion has a +2 charge, and the chloride ion has a -1 charge. Therefore, the compound is formed by the combination of one lead ion and two chloride ions, resulting in lead(II) chloride. The term "lead dichloride" would imply the presence of two lead ions and two chloride ions, which is not the correct chemical formula for this compound. **
