The Decomposition of Potassium Chlorate Hypothesis: Potassium chlorate decomposes into potassium chloride and oxygen gas‚ which means that when the glowing splint is inserted into the test tube‚ the flame will have enough fuel to fully reignite the splint. When the manganese dioxide is added‚ this will increase the rate of the production of oxygen in the reaction‚ without affecting the state of the manganese oxide. Materials: Test tube Retort stand Bunsen burner Scoopula Flint sparker 2cm of potassium

When you mix copper‚ silver‚ and nitrate together‚ you will end up with silver nitrate solution will turn blue (it has become copper nitrate). On the piece of copper‚ there would be a coating of solid silver. If a chemical reaction is going to be observed when chemicals are mixed‚ heated or any other means of altering the substance‚ then we will be able to predict the products formed. If it is observed that in the original versus the changed substance no new substances are formed‚ the change is reversible

CLASSIFICATION TESTS FOR ORGANIC HALIDES James Anand L. Regala‚ Sabrina Nicolle G. Sarte‚ Ann Michelle Siao‚ Michael Sibulo‚ Victoria Tan Group 8 2C Pharmacy Organic Chemistry Laboratory ABSTRACT This experiment is done to classify organic halides. Most organic halides are synthetic and are not flammable. One way to classify organic halides is by classifying its -carbon atom as primary‚ secondary or tertiary. If the -carbon is attached to one R group‚ it is then primary. If the -carbon is

tested for the PH value and it was neutral. The flame test was negative. There was no pigment in the flame. For our second unknown‚ the substance color was powdery-white‚ glittery‚ and clumpy. The odor was like rubber. When we tested the solubility in water in water it resulted soluble and in ethanol as well. The electrical conductivity was tested weak. The PH value was tested acidic. Just like the first unknown‚ this substance had a negative flame test.

Possessing and perusing unauthorized material is considered felonious. If discovered‚ then identified personages are penalized. Their novels are eradicated by flames and their belongings are obliterated. The government is portrayed as an oppressive and authoritative regime that discourage pursuing and preserving knowledge of any distinction. Any enlightened individual who inquires or expresses themselves is viewed as an unlawful tyrant by the civilians. Thus‚ the appeal of censorship transforms itself

mixture) will usually get increases which in turn increases the fuel consumption. And also the complete combustion of the fresh charge that entered the combustion chamber is not assured‚ because initially the capacity is higher‚ therefore the flame front of the spark ignited by the spark plug has to travel the additional distance of increased bore in order to fire the charge at the farthest corners of the cylinder thereby slackening the combustion process. There must be some modifications

Problem: What are the requirements for and characteristics of a candle flame? What are the products of the combustion of a candle? The purpose of this lab was to find out the properties and characteristics of a candle. Also the purpose was to find the remnants that the combustion of a candle leaves behind as gas. I learned that the candle that is burning releases a certain gas into the air. I also learned that limewater has a chemical reaction when exposed to that gas and turns red. Hypothesis:

Flame Test Lab - Post Lab Questions and Pre-Lab Questions Pre-Lab Questions: 1.When an atom absorbs energy‚ the electrons move from their normal state to an excited state. When an atom emits energy‚ the electrons move from an excited state to their ground state and give off photons. 2.Is the flame test a qunatitative test or qualitative test for the identity of an unknown? This flame test is both quantitative and qualitative. It is quantitative because we are measuring the wavelength
