Explanation: The idea here is that you need to use the number of moles of anhydrous barium iodide, BaI
{2}
, and of water, H {2} O
, to find the mole ratio that exists between the anhydrous salt and its water of hydration in the hydrate.
Answer: When British General Lord Charles Cornwallis and his army surrendered to General George Washington’s American force and its French allies at the Battle of Yorktown on October 19, 1781, it was more than just military win. The outcome in Yorktown, Virginia marked the conclusion of the last major battle of the American Revolution and the start of a new nation's independence. It also cemented Washington’s reputation as a great leader and eventual election as first president of the United States. In the summer of 1780, 5,500 French troops, with Comte de Rochambeau at the helm, landed in Newport, Rhode Island to aid the Americans. At the time, British forces were fighting on two fronts, with General Henry Clinton occupying New York City, and Cornwallis, who had already captured Charleston and Savannah, South Carolina, heading up operations in the south. With the Continental Army positioned in New York, Washington and Rochambeau teamed to plan a timed attack on Clinton with the arrival of more French forces. When they found the French fleet was instead sailing to the Chesapeake Bay, Washington concocted a new plan. By mid-September 1781, Washington and Rochambeau arrived in Williamsburg, Virginia, 13 miles from the tobacco port of Yorktown, where Cornwallis’s men had built a defense of 10 small forts (a.k.a. redoubts) with artillery batteries and connecting trenches. In response, Cornwallis asked Clinton for aid, and the general promised him a fleet of 5,000 British soldiers would set sail from New York to Yorktown.
With a small force left in New York, about 2,500 Americans and 4,000 French soldiers—facing some 8,000 British troops—began digging their own trenches 800 yards from the Brits and started a nearly week-long artillery assault on the enemy on October 9.
