Elements react to the different solution in different ways. Some show a chemical or physical reaction and some don’t show any kind of reaction. By using four elements and four solutions we are trying to see which out of all of these elements is the most reactive. We are trying to determine which element would be the most reactive? The elements are copper, zinc, silver, and magnesium. The solutions are copper nitrate, silver nitrate, zinc nitrate, and magnesium nitrate. If the element is in the alkali earth metals such magnesium than it should be more reactive with the solutions than most groups and the metals in the transition metals should have some reaction to some solutions. Alkali earth metals are pretty reactive while transition metals are less reactive. Analysis: …show more content…
This lab was done to see which of these elements were the most reactive. The order of the most reactive to least reactive would go like this: Magnesium was the most reactive with the solutions and reacted with all of the solutions in different ways such as bubbling with Mg(NO3)2, developed dark color with Cu(NO3)2, rusting with Ag(NO3)2, black dust coming off with Zn(NO3)2 and changed the solution’s color with Cu(NO3)2. Zinc was the second most reactive because it had the second most amount of reactions and reacted to the solutions by developing a dark ring and changing the solution's color with Cu(NO3)2 and creating a black dot in the middle with Ag(NO3)2. Copper is the third most reactive because it only reacted with Ag(NO3)2 by having the bottom of the surface change. Sliver is the least reactive because it didn’t react to any of the solutions. It makes sense that magnesium would have the most reactions because it is an alkali earth metal and alkali earth metals are pretty reactive. The rest were transition metals and transition metals aren’t that reactive with
An error that could have been present during the lab includes not letting the zinc react completely with the chloride ions by removing the penny too early from the solution. For instance, the percent error of this lab was 45.6%, which was determined by the subtraction of the theoretical percent of Cu 2.5% and the experimental percent of Cu 3.64% and dividing by the theoretical percent of Cu 2.5%. This experiment showed how reactants react with one another in a solution to drive a chemical reaction and the products that result from the
Discussion 1. Zn0 (s)+ Cu2+S6+O42-(aq) →Cu0(s) + Zn2+S6+O42-(aq) Zn0(s) → Zn2+(aq) + 2e- Cu2+(aq) + 2e- → Cu0(s) Zn0(s) + Cu2+(aq) → Zn2+(aq) + Cu0(s) Oxidant (oxidizing agent) is the element which reduces in experiment.
Cadet Eric Wiggins Date: 18 September 2014 Course Name: Chem 100 Instructor: Captain Zuniga Section: M3A Identification of a Copper Mineral Intro Minerals are elements or compounds that are created in the Earth by geological processes. The method of isolating metals in a compound mineral is normally conducted through two processes.
Metal cations can be identified based on the colors they emitted off when heated in a flame.1 When atoms of the ions that were tested are excited, their electrons move up to higher levels of energy.2 When the electrons relax and return to the original states, they emit photons of specific energy creating wavelengths of light that produces colors.3 The test wire and Bunsen Burner were used to excite the solution in the crucible. The standard metal cations that were tested and their outcomes are as shown in Table 1.
If all three of these elements are present,
The purpose of the lab was to discover the properties and the trends of the alkaline earth metals. In part A, the trend was as the atomic number increase in the alkaline earth metals the elements are more reactive. The alkaline earth metals each have two electrons in their outer shell and because all electrons want to become stable they are ready to give up the two electrons. When they are combined with water, the chemical reaction occurs differently based on each element.
1. Magnesium is an alkaline earth metal with an atomic number of 12 and an atomic mass of 24.305. It is part of the second group of elements on the periodic table located on the far left side of the periodic table. *CAUTION* Magnesium is a flammable metal!
In order to understand the experiment, the first piece of background knowledge one must know is what an element is. An element is a substance which cannot be broken down into a simpler matter. Elements are made of subatomic particles called protons, neutrons, and electrons. Protons and neutrons are found in the nucleus of the atom, while electrons are found in clouds surrounding the nucleus, called electron clouds. The charges in each subatomic particle differ, as protons are positive,
Introduction: The purpose of this experiment is to demonstrate the different types of chemical reactions, those including Copper. There are different types of chemical reactions. A double displacement reaction is a chemical process involving the exchange of bonds between two reacting chemical species. A a decomposition reaction is the separation of a chemical compound into elements or simpler compounds and the single-displacement reaction is a type of
4. What is an appropriate ionic radius for a couple of the missing elements in your table? 5. Are there any inconsistencies in the periodic table? Is there anything odd or that stick out of the normal pattern?
The ionization energy for the transition metals however are not as consistent and form little bumps on the graph The elements Beryllium, Boron, Magnesium, Aluminum, Zinc and Gallium form little peaks and troughs for both the atomic radius and the ionization energy The elements that are found on the peaks of the AR graph are the elements Hydrogen, Lithium, Sodium and Potassium. These elements are better known as the Alkali metals and are found in the far left column of the periodic table, also known as group 1. The elements that are found on the troughs of the AR graph are the elements Helium, Neon, Argon and Krypton. These elements are better known as the noble gases and are found in the far right column of the periodic table, also known as group
Inorganic mercury (Hg+ or Hg2+) in mercury salts also get formed. Salts of mercury (I)
P1 - Volumetric Analysis Made Easy The periodic table is split into 8 different categories. Group 1 consists of alkali metals which are very reactive. However group 7 contains very reactive non-metals. The periodic table starts from alkali and ends at noble gases (Group 8).
This paper will briefly describe the other three elements and
As well as this , their position on the periodic table makes them alkali metals, which means that they all have low boiling and melting points. As well as this , they will react violently when placed in water and will create a strong base and hydrogen gas as the products of the reaction. Group seven elements are known as halogens and consist of five non-metal elements with seven electrons in their outer shell.
