Lab performed: September 18 & 19, 2014 Due: September 26, 2014 Purpose The purpose of this experiment is to observe and compare synthesis, decomposition, single displacement and double displacement reactions and the physical and chemical reactions that occur as a result. Hypothesis If any chemical is added or brought near another chemical, then a reaction will occur and physical and chemical changes will be seen. Procedure Procedure and Materials taken from Nelson Science Perspectives 10 pages 244 to 247 Material changes include: Glowing splint used in placed of limewater in Station 2 Magnesium …show more content…

When the copper is heated, the flame of the bunsen burner changed from blue to green. The colour of the copper metal changed from a shiny reddish-brown colour to a dull gray-brown colour. When the magnesium is heated, it changed from a dull gray metal to a pale white colour. b) 2Mg (s)+ O2 (g) ----> 2MgO (s) Magnesium + Oxygen ----> Magnesium Oxide 2Cu (s) + O2 (g)----> 2CuO (s) Copper + Oxygen ----> Copper Oxide c)Copper (II) Carbonate forms the molecular compound of Carbon Dioxide when heated. Copper oxide remains as the ionic compound. When copper (II) carbonate and oxygen are heated, there is an oxidation reaction that occurs. The copper ion bonds with one oxygen ion while the carbon atom bonds with the remaining two oxygen ions. d) CuCO3 (s)----> CuO (s)+ CO2 (g) Copper (II) Carbonate ---> Copper Oxide + Carbon Dioxide e)When a glowing splint is brought near the opening of hydrogen peroxide, it re-ignites which means that oxygen gas has been produced as hydrogen peroxide …show more content…

For Station 4 , the magnesium and zinc turnings blackened when introduced to Cu(NO3)2 . Copper (II) nitrate, zinc nitrate and magnesium nitrate all changed colour when sodium carbonate was added. b)Magnesium is most reactive (#1). Zinc is second most reactive (#2). Copper is the least reactive (#3). c) Copper (II) Nitrate is the most reactive (#1). Zinc Nitrate is second most reactive (#2). Magnesium Nitrate is the least reactive (#3). d)It is the in the opposite order. While the magnesium metal is the most reactive, magnesium nitrate is the least reactive. Copper metal is the least reactive but copper nitrate is most

How Sodium Decompose Into When Heated Lab Report

798 Words | 4 Pages

At the particle level, NaHCO3 is composed of sodium ions, bicarbonate ions (HCO3-), and water molecules (H2O). When heat is applied to NaHCO3, the thermal energy breaks the bonds between the bicarbonate ion and the hydrogen ion. This causes the formation of carbonic acid (H2CO3). The resulting Na2CO3 is formed from the remaining sodium ion and the carbonate ion (CO3^2-), which is produced from the decomposition of the bicarbonate

Compare The Formation Of Cu (Oh) 2 To The Rate Of Reaction Lab Report

907 Words | 4 Pages

This experiment was composed of five reactions: The formation of Cu(NO3)2, the formation of Cu(OH)2, the formation of CuO, the formation of CuSO4, and the formation of Cu(S). For Reaction 1 which was the formation of Cu(NO3)2, the mass of the copper wire was taken in an analytical balance so that it can be compared to the final mass of copper at the end of the experiment. The copper wire was bent slightly and was laid flat in a 250 mL beaker so that the 16 M HNO3 solution could cover the whole wire. In the fume hood, a disposable pipette was used to distribute about 4 mL of 16 M HNO3 into the beaker with the copper wire.

This means that all of the elements in the same group have a main aspect in common, except for a few exceptions. These elements react with the same specific compounds. This was used to identify the order of the groups from left to right and to determine which elements go under which group. Some research was conducted to identify all the names of the groups ranging from element number one to element number 20. Once all group names were recorded, it was researched which groups react with which compounds that are given on the element cards.

Double Displacement Reaction Lab Report

1327 Words | 6 Pages

Another property that indicates a double displacement reaction occurred is the formation of gas. This was seen through three of the reactions performed in this lab; sodium carbonate with hydrochloric acid, sodium carbonate with sulphuric acid, and sodium hydroxide with ammonium chloride. In the sodium hydroxide and ammonium chloride reaction, when the two solutions are mixed, bubbles began to form rapidly. This clearly indicated that a gas was released when the reactants were mixed. Lastly, a property that indicates a double displacement reaction occurred is a temperature change.

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

If the water changes colors after it’s added, that means the mixture is a base. Observations recorded on this step focused mostly on physical changes. To go even more in depth for part A, magnesium was also tested for reactivity. The steps for Mg are consistent with the steps for Ca, apart from that in this instance, the test tube is boiled after the metal is added to the water. Observations were still recorded.

Lead Is More Active Due To Most Active Out Of Three Metals

321 Words | 2 Pages

Referencing our data, it can be determined that out of the three metals, Pb, Cu and Zn, it is shown that Lead (Pb) is more active than Copper (Cu) due to single-replacement reaction that took place. Lead had replaced Copper in the solution. Zinc (Zn), however, had replaced Lead thus leaving Copper to be the least active leaving Zinc to be the most active out of the three. In order of activity from least active, to most active, the metals would be lined up as following: Ag, Cu, Pb, Zn, Mg. From this lineup, it was be determined that hydrogen is more active than the elements silver and copper yet less active than zinc and magnesium.

Nitric Acid Experiment

789 Words | 4 Pages

Research Question: How does the concentration of the nitric acid affect the the time for the magnesium to dissolve or react. Hypothesis: If the concentration of the nitric acid is lower, the magnesium strips will dissolve slower and each time the concentration acid is higher the magnesium strip will dissolve faster. The reason for magnesium strips to dissolve faster when the concentration of the nitric acid is higher is because the reaction of this experiment is exothermic and when more energy is given out the faster the magnesium strips will dissolve. Collision theory is when different reactions collide at different rates, a slow reaction have a low rate of reaction and a fast reaction have a high rate of reaction.
