Answer:

Due to addition of acidic or basic solution.

Explanation:

Water equilibrium varies with pH because with the addition of acidic solution the pH of the solution decreases due to the presence of H+ ions which also increases the concentration of H+ ions in the water solution while on the other hand, by the addition of basic solution the pH of water increases due to the presence of OH- ions which also increases the concentration of OH- ions in the solution.

Answer:

1. Life is slow to change, we are now freed from the shackles and bonds of slavery but we are still imprisioned by the unrealistic thinking of our former masters. We work long hours for minimal pay, live in bad conditions, and have little to eat. Obtaining an education and figiting for our rights is difficult.

2. We were offered free land and a mule. but is it enough to support our families. Schools have been started but we need our kids help to work the lands.

3. Our challenges are many, we struggle with making enough money to support our families, we live in the worst conditions and are ridiculed everywhere we go. Our education is lacking and we have no way to better ourselves.

4. Before the war we woke early and worked the fields, we were slaves and had no choice in our lives, we were sold at the will of our masters and often seperated from our families. During the war we struggles to know what to do, many of our masters are serving in the war, we are offered the opportunity to fight for the north but must leave behind our women and children and what will become of them. After the war while on the surface much has changed when you look closer you see that it really has not, many of us continue to work for our former masters for meager pay, we can not support our families and work long hours.

5. The greastest change from the war is we are now free and if we have the means we can seek better opportunities for ourselves.

6. My hopes for the future is to be free of this cycle we are in, working for our former masters, not having an education. My hopes is to truly be free and equal to those around me.

Viking Motivations
Scandinavia was very cold and made agriculture difficult. It was also becoming very overcrowded. Monks on the English island of Lindisfarne are surprised by violent raiders from the sea. This is the first record of Viking raids. Viking migrated from Scandinavia in the Summer to look for resources.
Polynesian Motivation
Scientists estimate that the sweet potato was introduced to Polynesia by 700 CE which supports theories that they had traded with South America. Polynesians wanted to explore and trade to get resources that they didn't have on their islands.
Viking Techniques
Vikings had really long, strong ships made of oak that contained one mast and a square sail. They were often called "dragon" ships because they often had carved dragons protruding from the ends. In 836, a fleet of possibly 35 Viking ships invade Devon which is in England.
Polynesian techniques
The Polynesians used deep-sea voyaging canoes and oral sailing traditions such as songs about stars for navigation. A Polynesian canoe was found that had been buried in mud when a tsunami hit the island of Huahine near Tahiti somewhere between 850 and 1100.
Polynesian Extent of Exploration
By 1,000 CE, the Polynesians had already reached South America and returned. The Polynesians reached places as far as modern California, as evidenced by fish hooks.
Viking Extent of Migration
In 1,001 it is believed that Leif Erikkson reached the American coast. The Vikings are said to have reached North America about 500 years before anyone else.
Reasons for end of Polynesian Migration
The Polynesians stopped going and coming back, instead, they started settling in places like Hawaii, which was settled 1000 and 1300. The Polynesians' last stop in the Pacific was in the Cahtham Islands in 1300
793
Reason for Vikings End of Migration
The Vikings slowly became integrated with European cultures and Scandinavian countries were converted to Christianity. Many European coastal cities became more fortified and were better equipped to protect themselves aganist Viking raids. A common marker for the end of the "Viking Era" is 1006, which is the year of the last major Viking incursion into Europe. It was the Battle of Stamford Bridge where the Norwegian King Haraldr attempted to reclaim a portion of England and lost.
