Investigating the Temperature at Which Soap Powder Will Perform Best At

By extrapolating from the curve, the concentration of the unknown solution is ≈ 1.9mg.mL. The rate of reaction increases linearly with an increase in the substrate concentration.

The mixture was heated at 120°C using an aluminum block and was stirred gently. After all of the solid dissolved, it was heated for 20 additional minutes to ensure the reaction was complete.

Dimethyl Fumarate was not successfully created during the course of this particular experiment, likely because of a failure of the bromine to mix with the other components of the test tubes. It was observed that the bromine had formed a separate fraction at the top of the rest of the test tube contents, and because of this the necessary reaction could not occur in substantial amounts for a precipitate of dimethyl fumarate to form. The amount of bromine that was in contact with the dichloromethane and dimethyl maleate was simply too small for a significant reaction to occur. The data discussed below is sourced from Alexander Boley. Alex reported the melting point range to be 94-97°C, with an accepted range of 102-105°C. The lower boiling point is most likely due to the compound not being dried sufficiently before the melting point was tested. Alex also reported isolating 0.348 grams of dimethyl fumarate. Since he utilized 0.5 g of dimethyl maleate solution, and the accepted density of dimethyl maleate is 1.153 g/ml, the theoretical maximum amount of dimethyl fumarate that could have been obtained is 0.5765 g; dimethyl fumarate would be present in the same amounts as it's steroisomer because of their identical constitution, so dimethyl maleate's density is a valid input for calculating the final amount of product. The result indicates that his percent yield was 60.36%. The percent loss indicated could be attributed to

Cleanse is an Australian body soap company who produce and wholesale their products out to supermarket chains such as Woolworths and Coles. The company has been operating for over 3 years and has established a head office in Brisbane and Sydney with over 200 employees in its Australian operations. In addition to its Australian operations, Cleanse also has a branch in Delhi, India where they produce the same product and wholesale Cleanse products

I believe mystery powder 14 is powdered sugar (sucrose). I was first able to eliminate both of the known flours, the cornstarch and the baking powder with a vinegar solubility test because the powder immediately fizzed and, after being stirred with a toothpick, dissolved. The powders I was able to eliminate either did not bubble or did not dissolve into the vinegar. Noting the physical properties, that the powder was a bright, opaque white that formed small clumps, I predicted that the powder was powdered sugar. To confirm my prediction, I performed three other tests. The heat test was consistent was powdered sugar, resulting in streams of smoke, a sweet smell, and a caramelization of the powder. The sodium hydroxide (NaOH) test further support

The reaction will be complete after approximately 60 seconds. Observe where color develops, and consider what these results indicate. Record your results in Table 1.

Hypothesis: If the temperature (I.V.) of materials in the reaction are increased, the reaction time (D.V.) will decrease.

The wet, crude product was placed into the 50 mL Erlenmeyer flask. Small amounts of CaCl2 were added to dry the solution. The flask was sealed and the mixture was swirled and left to settle. Once

The solution is stirred with a stirring rod and stopped as soon as the pink colour disappears.
