Chemical Proportionality (Carbonate and Hydrochloric Acid) Introduction: The purpose of this experiment is what happens when a solid substance‚ a metal carbonate is added slowly to a solution of an acid. We are finding methods of determining acid concentration. For us to balance certain equations‚ we will use a stoichiometry. For this experiment‚ we will need to set up the ratio and finding the concentration of HCI. Procedure: • Grab 4 different beakers. • Add a small amount of sodium carbonate

This experiment will test the suggestion that the enthalpy change between a metal and a solution of a salt is related to the relative position of the two metals in the reactivity. Presumably the further apart in the series the bigger the enthalpy change will be. The experiment is as follows‚ 1) Zn(s) + CuSO4(aq) ZnSO4(aq) + Cu(s) 2) Zn(s) + Pb(NO3)2(aq) Zn(NO3)2 (aq) + Pb(s) Both of the solutions will be in 1mol.dm-3 Apparatus: Distilled Water Polystyrene Cup

IV‚ took the throne. His subjects were not prepared for what was to occur in the coming years under the new ruler. The beginning of Amenhotep IV’s reign didn’t hold too many changes but as the years progressed‚ one by one‚ transformations to the Egyptian way of life (religion especially) began to take place. These changes that were initiated were not only in religion‚ but in art‚ writing‚ politics‚ architecture‚ and all were based on his new philosophy. Egypt had always been known for worshipping

Lab 4: Physical & Chemical Properties Purpose: The purpose of this lab is to distinguish if different substances react to heat or cold and if a solution is added to it during the experiment will it change the substance or leave it the same. Throughout the different tests each substance is put through a series of tests to determine if it changes in any way in regards to color‚ odor‚ or consistency from the start of the experiment. The results will be documented in table 1. Data Table 1: Solubility

How much did you know about snorkelling before starting this unit? Previously to beginning the component of snorkelling‚ I assumed I was fairly confident with this activity as I had been on numerous personal snorkelling trip. However‚ I was initially oblivious to the safety rules as well as correct techniques used whilst snorkelling to enhance an overall safer and pleasurable outing. Therefore‚ the score I rate myself of how much I knew about snorkelling before starting the unit is an average 5.

Question 3: How did your family define this identity to you during childhood? I was raised in a christain home and so I was taught about the importance of loving and respecting others and no matter what ethinic group they belonged. The identity of this group as defined to me‚ during my childhood is that we should have the ‘we’ mentality as it stresses about the needs and goals of others rather than your own needs‚ which played a vital role for my identity (France‚ Rodriguez‚ & Hett‚ 2013).

Chemical Bonding Chemical compounds are formed by the joining of two or more atoms. A stable compound occurs when the total energy of the combination has lower energy than the separated atoms. The bound state implies a net attractive force between the atoms ... a chemical bond. The two extreme cases of chemical bonds are: Covalent Bonds Covalent chemical bonds involve the sharing of a pair of valence electrons by two atoms‚ in contrast to the transfer of electrons in ionic bonds. Such bonds lead

To sum up what I’m saying the way we act affects our relationships and causes some to be made and some to be changed or even lost. This theme is present in the stories “What‚ of This Goldfish‚ Would You Wish?”‚ “The Wife’s Story”‚ and “My So-Called Enemy” as they all have to do with the way relationships affect us. In the short story “What‚ of This Goldfish‚ Would You Wish?” by Etgar Keret the main character Sergei acts consistently with his three wishes. Each time he uses a wish he uses it to help
