My results of part B shows that a penny can hold 21 drops of water on the top. This relates to adhesion since the penny that is copper is attracted to a different substance which is water. When the drops hit the penny‚ the adhesive force of the water and the penny keeps the water from falling off the sides. It also shows high cohesion since the water molecules are attracted to each other. In a water molecule it has a hydrogen bond of oxygen and hydrogen since they are attracted to one another. It

The discovery of copper does not have an exact date. Copper is said to be a prehistoric element. This element was said to be first discovered around 8000BC. The ancient civilizations started to take the copper out of the ore they found around 4000BC. This is when copper started to be put to good use. Early civilizations discovered that copper is malleable and is sharp. They realized they could make copper into tools and weapons. This was easier than the stone that they were originally using. This

science can be seen on a higher level‚ as a science of problem solving. Problem solving requires precision‚ creativity‚ and careful reasoning. In the end the final product of our progress is the result of our decisions that we had to take. In Three Penny Opera by Bertolt Brecht we can notice the presence of the conflict between self-interest and love. Many of the characters’ decisions create a conflict between self-interest and love. In a capitalist society in which competition is rewarded by disrespect

17 g Determine the percent yield of NaCl in your experiment‚ showing all work neatly in the space below. (5 points) 7.17 g / 8.8197 g = 0.81295 = 81% If you had not heated the product long enough to remove all of the water‚ explain in detail how that would have specifically affected your calculated actual yield and percent yield. (5 points) The product’s mass would be greater making the calculations adjust. If my actual yield is greater‚ then so would my percent yield.

Identification of a Copper Compound by Percent Mass Unknown Compound: #9 Abstract: The objective of this experiment was to identify the unknown pure copper salt compound of #9. To do this‚ the mass of copper in the unknown was calculated and then divided by the mass of the whole compound to get the percent copper. The molecular weight was also calculated by dividing mass of copper compound used by moles of compound in unknown sample. The percent copper averaged out to 31.6% while the molecular

factors. Many believe that it is hard work that bring them success‚ others think that luck is more important. I totally agree with the quotation‚ because I believe that success comes from hard work‚ as Newton said “Genius is one percent inspiration and ninety nine percent perspiration”. People often believe that luck is something that is beyond our control. How can we know when we get a big contract? How can we predict when our experiment give way for a new discovery?
