1. Use Sandpaper to clean the Cu.
2. Hold the Cu with the crucible tongs in the hotest part of the flame for about 2 minutes.
Note the change in the Cu.
3. Put an evaporating dish near the base of the burner, and with crucible tongs put a
piece of Mg in the flame and do not look at the flame.
4. Place 2 heaping microspatulas of CuCO3 in a test tube. note appearance.
5. Put test tube over the flame for 3 minutes and CO2 will now be present.
6. Put HCl and Zn in a test tube. Note changes.
7. Hold a test tube over the test tube with the HCl and the Zn. After thirty seconds put a
burning wood splint in the test tube, a pop will indicate the presence of hydrogen gas.
8. Add about 5ml of CuSO4 in a clean new test tube. Put a piece of Zn in the solution .
Note appearance of solution before and after Zn is in the tube.
9. Add 2ml of (Zn(C2H3O2)2) to a new test tube. Then add about 2ml of Na2PO3 to the
test tube. Observe Changes.
10. Add about 5ml of Na2SO3 to a new test tube. Then add about 1ml of 6 M HCl. Smell,
but not directly.
On step two the copper turned black when in the flame. After the Mg would flared in the
fire, the Mg turned to ashes. The CuCO3 was a white powder, and after it was in the
flame CO2 was present and the CuCO3 turned black. the Zn and HCl started to bubble
and their was a pop indicating Hydrogen gas. The Zinc turned black and the clear CuSO4
became green. The (Zn(C2H3O2)2), and the Na2PO3 became mirky white. In closing I
could not Smell the Na2SO3, and the HCl.
Their were many Chemical Rxn in this lab and are stated in the observations.

AIR POLUTIONAIR POLUTION Problem The first thing people see, in the morning, when they walk outside is the sky or the colored sun. Is this world giving us the privilege of seeing the natural colors of the sun through all the layers of pollution within the air (Dinanike 31)? Not only are beautiful sights such as this hidden behind the pollution this world causes everyday, but an increase in diseases, infections and death occurs. What causes pollution? What can we do to prevent it, and get rid of it? Is it fa

Illuminating the Path of Progress Illuminating the Path of Progress Thomas Alva Edison is the most famous inventor in American History. Edison designed, built, and delivered the electrical age. He started a revolution that would refocus technology, change life patterns, and create millions of jobs. He became famous for his scientific inventions, even though he was not a scientist. His real talent was his ability to clearly judge a problem and be persistent in experimenting. He was the master of the trial and error method. Thoma

Greek mythology tells of the winged horse Pegasus, ancient Persian myths tell of winged bulls that guarded the royal halls, and a 4000 year old Chinese story, from the Annals of The Bamboo Books, describes how the Emperor Shun escaped from captivity by donning the work-clothes of a bird.

He caused a new revolution in thinking about how thinking develops. In 1984, Piaget observed that children understand concepts and reason differently at different stages.

However, there were few minds who were able to put all of these ideas together. One of these minds belonged to Claudius Ptolemy, or just Ptolemy as he is commonly referred to. We know almost nothing of the chronology of Ptolemy's life, and we don't even know his birth or death dates. We do know, though, about his ideas in several fields, which include geography, astronom

DeceptionDeception Is psychological science ever likely to devise an infallible method to detect deception? If so, how? If not, why not? The detection of lies is a highly complex process as there is great variation between individuals. This makes the process of devising a test that will apply to everyone and be 100% accurate very difficult if not impossible. There will always be an individual motivated enough to devise a way of falsifying information. Some tests are more reliable than others but without

A water filled plastic dish was placed on paper and the light was refracted as it entered the dish. Lines were drawn by looking through the water dish and lining up pins placed on certain areas on the paper. The angles between certain points on the paper and the perpendicular line were measured which were the angles of incidence of the rays. The average
SuperconductivitySuperconductivity Superconductivity is the ability of certain materials to conduct electrical current with no resistance and extremely low losses. This ability to carry large amounts of current can be applied to electric power devices such as motors and generators, and to electricity transmission in power lines. For example, superconductors can carry as much as 100 times the amount of electricity of ordinary copper or aluminum wires of the same size. Scientists had been intrigued with the concep

Every year 200000 to 570000 people die from outdoor pollution alone Th Every year 200,000 to 570,000 people die from outdoor pollution alone. This is about .4 - 1.1 percent of the annual death tolls. Pollution is one of the biggest world problems today. It takes its toll on many, while others just get passed over and aren’t affected at all. But we don’t know who will be passed over and who’s life will be taken next. So we must be prepared with knowledge about what we are doing to ourselves. Pollution is a world problem because it affects wildlife all over the glob

Laser light is an entirely new kind of light, more brilliant, more intense than anything found in nature. Laser light can be so powerful that it can vaporize any known material on earth in a fraction of a second. It can bore holes in the toughest metals or easily pierce the hardness of a diamond. In contrast, less powerful, exquisitely precise beams from other kinds of lasers can be used to per

The beginning of compounding dates back to medieval times with priests, monks, and medicine men. Specialization first occurred in the early 9th century in the civilized world around Baghdad. Over time it gradually spread to Europe as alchemy evolved into chemistry as doctors began to abandon beliefs that were not demonstrable in the physical world. During this time,

Most cancers take the form of tumors, although not all tumors are cancers. A tumor is simply a mass of new tissue that serves no physiological purpose. It can be benign, like a wart, or malignant, like cancer. Benign tumors are made up of cells similar to the surrounding normal cells and are enclosed in a membrane that
