The powdered iron is magnetic, but the powdered sulfur is not. If they both form a mixture in a beaker at room temperature the iron retains its magnetic properties.
<u>Explanation:</u>
Mixing of iron with sulfur, No chemical reaction occurs. This a type of physical reaction so no changes occur.
The iron retains its magnetic properties. If this mixture is heated for a certain degree celsius.
Then it undergoes a chemical reaction. The iron mixed with the sulfur to form iron sulfide(FeS).
Answer:
Valley Forge functioned as the third of eight winter encampments for the Continental Army's main body, commanded by General George Washington, during the American Revolutionary War. In September 1777, Congress fled Philadelphia to escape the British capture of the city. After failing to retake Philadelphia, Washington led his 12,000-man army into winter quarters at Valley Forge, located approximately 18 miles (29 km) northwest of Philadelphia.
Explanation:
They remained there for six months, from December 19, 1777 to June 19, 1778.At Valley Forge, the Continentals struggled to manage a disastrous supply crisis while retraining and reorganizing their units. About 1,700 to 2,000 soldiers died from disease, possibly exacerbated by malnutrition. Today, Valley Forge National Historical Park protects and preserves over 3,500 acres of the original encampment site.
It lead to American Independence because before the war the colonies had salutary neglect so England was not controlling what they do. But after the war in 1763 King George III issued the Proclamation of 1763 which said settlers could not settle west of the Appalachian mountains. He did this because England was in debt after spending so much money on the war so he could not send troops to fight the remaining Natives which were a danger to the colonists. (They had killed over 2,000 of the settlers in that area). After this colonists became angry because they could not settle the land they fought and died for (since the war was fought in America not in England). You must also remember that the colonists are British but King George III, Parliament and the rest of the English citizens do not consider them citizens but subject since they do not live in England or were born there. (They were born in the colonies) So when King George III sent out the act like the Sugar, Stamp, Declaratory Tea Quartering, and Townshend acts, they did not apply to anyone in England but only to the colonies, to help England not be in debt. (The king and Parliament believe that England became in debt to help the colonies have land to settle, so therefore they must pay to get England to the way it used to be) The colonists are angry at these acts because they tax the things that they want like sugar,paper, legal documents, tea, paint, lead, glass, playing cards. All of these things were taxed during different times though. The only Act that was a tax in disguise was the Quartering Act where colonies had to house soldiers in barracks provided by the colonies.So the effect of all of these acts is that the colonists are furious so they smuggle goods which causes the Writs of Assistance where British can search any home at any time for smuggled goods. (similar to a search warrant). Another effect is that the colonies split and some become loyalists who are loyal to the king and the others become patriots who are not and just want to have peace. After some time the patriots become to see themselves as a whole and as Americans and not just as separate colonies. Then the Boston Massacre happens and things get heated. After that the Boston Tea Party occurs where colonists dress up as Native Americans and dump 342 chests of tea into the Boston Harbor (worth over 1 million dollars today!). After this, Parliament and King George III issue the Intolerable/Coercive Acts which enforces a stronger Quartering Act where soldiers must stay in the colonists' homes and the colonists must provide the room, food, board, beer and other necessities, they close the Boston Harbor until all of that lost tea is paid for, a new governor (General Gage) governs Massachusetts and enforces martial law, also the kings sends 10,000 soldiers, and any Officials charged with crime will have their trial in England and not in the colonies. This draws the line between England and her colonies and pretty soon small battles like Lexington and Concord (where the British were defeated) happen as well as events like the 1st Continental Congress. After this things start to fall in place and the Revolutionary War takes place. I hope this answers your question!
Hope this helps!

Answer:
B) they were killed by diseases brought by the Spanish, such as smallpox and influenza
Explanation:
Most of diseases were normal to the Spaniards, so it did not affect them, but for the Mayans it was a killer, as they don't have the natural immunity, unlike the Spaniards.
