Radiator fluid Coolant Radiator fluid is an essential unit of the auto since it shields the motor from the solidifying harm. At the point when the water gets changed over into ice‚ it represents an issue for the auto. Liquid catalyst is really the warmth exchange liquid which is utilized to ensure the solidifying. In both the sunlight based water radiators and the HVAC chillers it is utilized. Concoction are added to the water keeping in mind the end goal to keep the solidifying. Liquid catalyst

Discussion and Interpretation of Results The addition of HBr to 1-hexene created a 2-bromohexane‚ as indicated from the ethanol silver nitrate test and sodium iodide/acetone test. The observations when the product was subjected to these tests were similar to what were observed with the 2° bromide compound. When subjected to the silver nitrate test‚ the product produced a precipitate at the same rate of the 2° bromide compound‚ and the product produced a hue of yellow that was also similar to the

Problem: What methods could be used to extract materials from the given mixture that contains iron filings‚sand‚salt and small stones? Background There are things that must be understood before doing this lab. The first thing that must be understood is a mixture. A mixture has two or more pure substances‚ and the substances keep their chemical compositions (study.com).The next thing to apprehend is filteration. Filtration is a method used to separate a solid that isn’t dissolved in water. Another

It must be noted that the actual undertaken procedure included a few differences from the ideal protocol. A total of 7 ml of extra water was added to the reaction before it was treated in the separatory funnel due to there being so much white precipitate that the mixture had turned to a paste as opposed to a liquid. The aqueous layer was accidentally not drained between adding the two different ether fractions‚ so the aqueous layer was drained after that and 10 ml of extra diethyl ether were added

Objective The objective of this experiment is to perform a steam distillation using a microscale distillation apparatus and isolate a natural product from cloves. Introduction By performing steam distillation we can isolate eugenol at lower temperature than its usual boiling point of 248 degree Celsius. Eugenol belongs to a category called essential oil. Many of these compounds are used as flavoring and perfumes and in the past were considered the essence of plant from which they were derived

In the fume hood‚ approximately 2g of Ca(OH)2 was dumped from a vail into a 250ml beaker. To avoid any left-over Ca(OH)2 inside the vail‚ certain amount of distill water wad added to it‚ and the vail was shook several times after the lid was closed. Pouring the solution in the vail into the beaker‚ and add distill water until it reached the 100ml line. Then‚ the beaker was put on top of a magnetic stir with a magnetic stir bar placed in it. Turning on the magnetic stirrer and allowing the stir bar
