Get all the equipment’s ready and put them on a table. Take a pair of goggles and put them on and make sure hair is tied up‚ if long‚ using any sort of hair band. Take the 100ml glass beaker and place it under the water tap’s opening‚ the place where the water comes out from‚ then turn the tap on. Do not turn the tap off until the water inside the beaker reaches the 50ml mark‚ to ensure that there is only 50ml of water in the 100ml beaker. Then take the beaker and place it somewhere safe on the table

The progress of the reaction was monitored in my case using two TLC plate. It first started off with the spotting of Standard benzoin and benzil which were provided in the lab and followed by the addition of the reaction mixture at once it starts changing colour/boiling‚ then at 10 and 20 mins into the reflux. Once all the necessary steps were spotted‚ the TLC plate was placed in in a beaker containing CH₂Cl₂(methylene chloride)‚ which was used as the developing solvent in this experiment. To check

Experiment 7 INVESTIGATING STOICHIOMETRY WITH SODIUM SALTS OF CARBONIC ACID Introduction In this experiment we are going to get a better understanding of chemical stoichiometry. We are going to be reacting sodium bicarbonate (NaHCO3) and sodium carbonate (Na2CO3) with hydrochloric acid (HCl). To start off the mass of two unknown substances (being the sodium bicarbonate and sodium carbonate) will be taken. We will need to construct balanced equations for both of the reactants with the HCl and

1. What is the molarity of a solution of ammonium chloride prepared by diluting 50.00 mL of a 3.79 M NH4Cl solution to 2.00 L? 2. A student takes a sample of KOH stock solution and dilutes it with 100.0 mLof water. The student determines that the diluted solution is 0.046 M KOH‚ but has forgotten to record the volume of the original stock solution sample. The concentration of the stock solution is 2.09 M. What was the volume of the original sample of stock solution? 3. A chemist wants to prepare

The leaders of the political parties of the Canadian House of Commons ‚ with the assistance of ’whips’‚ very strongly discipline their party members to vote on issues as a single entity‚ especially in plenary sessions (Olson‚ 2003).

Head injuries can take students out of the game for the rest of their lives‚ and make their lives different forever. Concussions are a big problem with sports today‚ but so is the amount of pressure put on these student athletes. limiting sports can help athletes by limiting the pressure put on them.

Chapter 4: Limiting Liberalism or Generous Germany? If we now have to start apologizing for showing a friendly face in response to emergency situations‚ then that’s not my country. - Angela Merkel. To repent for WWII floods of Syrians‚ Afghans and Iraqis have entered Germany‚ and there “…suddenly become an image of openness‚ generosity and solidarity.” (Godin‚ 2015).

Our inspiration for this experiment came from a lecture in class about the Los Angeles council agreeing that there should be a law limiting homeless people’s belongings to what can fit in a trash bin. This would force the homeless people to throw away large portions of their belongings to benefit the city from not having “trash” on the streets. According to the L.A. times‚ the legislation California believes that this law will “limit storage on sidewalks‚ parkways‚ and alleys citywide to what homeless

Using Stoichiometry to Determine Gases Produced in a Reaction Introduction Magnesium is a metal and is the third most commonly used metal by chemists. Some would say it is the least dense structural metal. Its lightness is often alloyed with aluminum. Magnesium is also used in racing car wheels called MAG wheels. Many car-manufacturing companies will use magnesium and aluminum because of the lightness of the metal. Both of these metals are reactive with acids. The most common acid in they
