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

Naming Chemical Compounds General Information: Scientists all around the globe use a standard method for naming chemical compounds. The standards were set up by an international committee sponsored by the International Union of Pure and Applied Chemistry (IUPAC). Having this standard makes life easier for people who use these compounds everyday. It would be tough to set up any experiment if scientists everywhere used different names for the same compound. It would also make the lab a

Identifying Ionic Compounds Written by Ashleigh Lara. In our experiment we were given 5 different cations who’s mixture of anions ranged from five to three different solutions. At every single station we were given the following materials a spot plate‚ a dropper‚ and the chemicals used to mix with our main substance. Each substance received 3 drops of the different chemicals which were able to give us an observation of what the compound was made into. Many of our experiments color‚ texture and solubility

money‚ it is very common to hear words such as interest‚ usury‚ risks‚ etc. We mention these words very often and many times we do not even know what they mean. But this is not it; it gets more interesting when we start linking all this stuff with other topics such as religion‚ ethics and moral values. Going back to the beginning‚ when we start talking about banks and money‚ it is known by everybody that banks’ main business are the loans and the interests they ask for them‚ which many people do not

I. Abstract The common organic compounds provide us with nutrients are sugars and starches‚ carbohydrates‚ proteins‚ and lipids. In this lab‚ qualitative tests are performed to identify the presence of organic compounds in food using indicators‚ chemical substances that react in a certain way when a particular substance is present. We put one indicator into the each test tube containing different solutions at a time to see what organic compound is present. The color change in the indicator tells
