Silver nitrate

Observation My selected artifact is two photographs that Benson took of the organization MOVE, when they were prevalent in Philadelphia. The first, MOVE 78’, depicts 8 members of the group sitting and standing near a fire that is in a large trash can. They appear in front of a dilapidated house. It seems to be either winter or fall, given that many of the members are wearing what seem to be thick coats and the trees are bare. The group consists of mostly males and it is unclear what has been…

equation for the reaction of our gunpowder is 10Na NO3 + 8C + 3S → 2 Na2 CO3 + 3Na2SO4 + 6CO2 + 5N2. This shows that Sodium Nitrate is reacting with Carbon/Charcoal and Sulfur to form Nitrogen, Carbon Dioxide, Sodium Carbonate, and Sodium Sulfate. In gunpowder, the Sodium Nitrate is decomposed at a high temperature to produce oxygen for the gunpowder reaction. Since the Sodium Nitrate is able to…

Bam! Bam! Bam! goes the gun of a soldier. Have you ever wondered where gunpowder came from? Gunpowder, as well as silk and paper, are just some of many objects traded along the Silk Road that have an impact on our lives today. To begin with the silk road was a trading system and gunpowder was one of the objects exchange on the silk road.Gunpowder is made out of charcoal but it is also known as black powder. Gunpowder is a explosive chemicals which means it is very dangerous. Back to what I was…

Additionally, the ice pack reduces pain and swelling during the recovery post or pre-surgery. The extra-large cold pack is sized to provide adequate coverage for the back, hip, abdomen and thigh. FLEXIBLE COLD THERAPY:…

which heat is released. After researching and testing multiple compounds, I have concluded that Ammonium Nitrate is the best compound for a cold pack. One of the most important factors in choosing a compound for a cold pack is how cold it will get, because of this, Calcium Chloride is a bad choice for a cold pack as it is an exothermic reaction and releases heat. On the other hand, Ammonium Nitrate had the largest drop in temperature, with a drop of 9.6° celsius. This is good for a cold pack…

few different parts such as Potassium Nitrate, Charcoal, and Sulfur and they use different chemical compounds to create three kinds of results: A tremendous "boom" A bright light Heat What is the recipe for black powder? Why do you think Potassium Nitrate, Charcoal, and Sulfur become explosive after they are ground together? Black Powder is a mixture of Potassium Nitrate, Charcoal and Sulfur. The Sulfur and Charcoal act as fuels, and the Potassium Nitrate is an oxidizer. Black powder is used…

How gunpowder changed warfare How gunpowder was invented is that some scientists in china were experimenting Saltpeter a powerful agent potassium nitrate. It was used in medical compounds for years until a man thought about mixing the potassium agent with sulfur and charcoal, it had a result of a mysterious powder. Some observers said that smoke and fire the scientist’s body parts were burnt and the houses that they were working at burnt down too. The powder was used by the reigning Sung…

China really only started coming to the Olympics in the early 90’s and wasn 't really known for anything athletic before then. In 2008 China ranked #1 overall in the Olympics finishing with 51 gold medals, 21 silver medals, and 28 bronze medals. China 's best sports at the Summer Olympics are badminton, diving, gymnastics, shooting, table tennis, and weightlifting. China is known for soaring in table tennis and has won 23 of 27 gold medals for table tennis in…

fit and just lay my chair back and was scowling. At this time Stef says “hey at least the radio still works”, and she hooked her iphone up to it and started playing relaxing music, which instantly flipped my mood. I think that her ability to see the silver lining in situations is one of the main reasons that I find it so enjoyable to be around…

Have you ever thought what if I had tried harder then I would have succeeded? Most likely you have and that is known as counterfactual thinking. Counterfactual thinking is the theory of what could have been. We tend to correlate our failures with counterfactual thinking. For example, if we had studied harder on that test and not gone out that night we might have gotten an A on the test not a B. We can also look at counterfactual thinking in a positive way and how that helps us in our lives. In…
