metal is on the left and the least active metal is on the right. Remember‚ sodium and copper are metals‚ too. B. Suppose you inserted a piece of copper into a solution of nickel chloride and observed no reaction. Then if you inserted a piece of iron into the solution of nickel chloride a nickel deposit formed on the bottom of the well in the well plate. Where does nickel fit into your activity series? The chemical reactions for the preceding question B are: Cu (s) + NiCl2 (aq) à no reaction

1. Introduction The Jominy end-quench test is a technique that has the ability to harden the steel by quenching. It is an essential feature of materials that determine the material’s selection for particular applications. The different types of steels and alloys that are used for hardening in an industry are done by this test and considering that this test is a standardised experiment [1]. 1.1 Aim The specimens that are used in this test are normalized in accordance with the standards. The purpose

I originally did a preliminary test with Iron wool where we used a similar method but Test the iron wool was held over the flame by tongs and not contained within a crucible. We learnt from this experiment the importance of the crucible to contain all of the metal for an accurate test because the iron wool broke off as it heated and we were left with a lot of the iron wool on the bench mats around the Bunsen burner so our calculation of the mass of iron oxide was not accurate as we had not contained

MATSE 259 Solutions to classwork #8 1. For a 99.65 wt% Fe – 0.35 wt% C alloy at a temperature just below the eutectoid‚ determine the following: (a) The fractions of total ferrite and cementite phase. (b) The fractions of the proeutectoid ferrite and pearlite. (c) The fraction of eutectoid ferrite. (a) This part of the problem is solved by application of the lever rule employing a tie line that extends all the way across the α + Fe3C phase field. Noting that the alloy composition is 99

temperatures but it becomes ductile and malleable when heated between 110°C and 150°C. It is a reactive metal that can combine with oxygen and other non-metals and will react with dilute acids to release hydrogen. Mostly zinc is used for galvanizing iron with more than 50% of metallic zinc goes into galvanizing steel and in the preparation of certain alloys. Then‚ zinc is added during industrial activities such as mining‚ coal and waste combustion and steel processing. Some soils are heavily contaminated
