1. Zhu Huiqin et al. reacted acenaphthylene with cerium ammonium nitrate in acetic acid medium and in the presence of polyethylene glycol to prepare 5-NITROACENAPHTHENE. The reaction conditions were mild, the selectivity was good, and the yield was high. Ceric ammonium nitrate is mainly used a...
To prepare acetic acid from acetonitrile, we can follow a series of steps involving hydrolysis. Here’s a step-by-step breakdown of the process: Step 1: Protonation of Acetonitrile- Starting Compound: Acetonitrile (CH₃C≡N)- Action: Treat acetonitrile with an acid (H⁺).- Result: The...
Lance Lund, a professor at Anoka-Ramsey Community College, was asked to prepare a promotional science video for the college back in 1995 that was to air on a local cable access channel. All went well until he inhaled some sulfur hexafluoride (SF6). The video never aired, but many more of...

If instead, we slowly add the nitric acid to the hydrochloric acid, the reaction proceeds gently. Excess heat is allowed to dissipate, and toxic gases evolve gradually. The evolution of toxic gasses is also why we never store aqua regia and especially don’t prepare it in a sealed receptacle...
Oat groat takes the longest to cook, as it comprises whole oats. Steel-cut, crushed, and rolled oats take less time to prepare. Unless the packaging says otherwise, people can make oatmeal by boiling the oats in cow’s milk, plant-based milk, or water. Cooking times will vary and can...
Prior to your run, start by inhaling through the nose, taking deep belly breaths up to a count of seven. Forcefully breathe out through the mouth until you have expelled all the air in your body. This breath will warm up and activate your core to prepare for the run. To Recover from ...
