Problem Which dissolves in water better, salt or baking soda? Hypothesis If salt and baking soda where put in water then baking soda will dissolve better than salt. Abstract The purpose of this project is to determine which material dissolves better in water between salt and baking soda. The hypothesis is If salt and baking soda where put in water then baking soda will dissolve better than salt. One teaspoon of salt and one teaspoon of baking soda were put in two separate transparent glasses of water and then the time of dissolving of each substance were calculated.
By doing this it also eliminates drug errors from happening, such as giving it to the wrong patient or giving the wrong dose. If these measures weren’t followed it could cause the misuse of a drug. The drug could go missing/ stolen and a person could have an overdose of it if they aren’t aware of what they are taking and how much they are taking. If the rules weren’t adhered to staff could be prosecuted for stealing or they could get sacked for not giving medication correctly, and the patients could become very ill and possibly end up
Having the same brand name as another product is also one of the things that are against the FDA’s regulations because this could protect the consumer from buying the wrong drug because of the similar names. If the wrong product was bought, it could have caused serious harm to the consumer, depending on the differences of the two
For reaction (II) Pb (NO3)2 + 2KI -> PbI2+2KNO3 Lead nitrate is soluble, so it gets written as ions. The same goes for potassium iodide and potassium nitrate. Complete Ionic equation: 2 K+1 + I-1 + Pb2+ + NO32- -> PbI2 + 2K+1 + NO3-1 Net Ionic Equation: Pb+2 + 2 I-1 -> PbI2 Warm-Up Exercise 2 In this lab you will mix 25 mL of 0.05M lead nitrate with 1.4 mL of 0.025M sodium carbonate. After the reaction occurs, you will filter the solution to remove the precipitate. You will then test the remaining solution for excess lead ion and for excess carbonate ion… Imagine that you mix the two volumes and then freeze frame the reaction so the it does not proceed: 1.
If your tube becomes clogged, try to gently flush it with warm (not hot) water. The water may need to sit in the tube for 5 to 10 minutes. Do not push hard when trying to unclog the tube, it may break. If this does not work, your doctor may need to change the tube. Site Infection Like any wound, your PEG site may become infected.
All matter may exist in any of three physical states of matter.In the graphic on the left the solid and liquid forms of water - ice are shown. | | Physical Changes:A physical change takes place without any changes in molecular composition. The same element or compound is present before and after the change. The same molecule is present through out the changes. Physical changes are related to physical properties since some measurements require that changes be made.Melting Point: As solid matter is heated it eventually melts or changes into a liquid state at the melting point.
Use your answers to Questions 1 and 2 to explain how a water-insoluble organic acid might be freed of non-acidic impurities. Water-insoluble organic acid can be freed of non-acidic impurities by adding strong base into it during fractional distillation. The water-insoluble organic acid will react with the strong to produce an ionic salt which is soluble in water. On the other hand, water-insoluble organic acid which are slightly soluble in water can be extracted by aqueous base from solution in an organic solvent. The fact that organic acid are weak acids and only partially dissociates in
Anette Santana * Ch.26 - Salt Exercise 7/8/14 Salt Exercise There are different types of definitions for salt. Salt is either a white crystalline substance that gives seawater its characteristic taste and is used for seasoning or preserving food. In this case salt is any chemical compound formed from the reaction of an acid replaced by a metal or other caution. Salt Is composed of the negative of an acid and positive ion of a base. One cool thing about naming salts is the names are related to the name of the acid that forms it.
The hunter process follows the same steps as the Kroll process except for the fact that sodium is added to the vessel and therefore, NaCl is the salt that is entrapped in the pores of the sponge formed. The chemical equation for the hunter process is as
Therefore he went to that shop and got two tattoos in his body. However, I believe that people should not get tattoos because they can cause short-term and long-term health issues. Tattoos can also lead to death. If you want to have tattoos you have to think about what are the dangerous things you may have. The first reason why I do not think getting tattoos are not good thing to do is because some tattoo shops use old needles and have unclean, in safe environment.
