A single displacement reaction is also commonly known as a single-replacement reaction. It’s a type of chemical reaction when elements react with compounds and take the place of another element in that same compound. An example of this occurring is; A + BC → AC. As you can see the replacement is similar to the original object, but the only way in which the element was able to be replaced was if the element taking its place was more reactive. Another thing to note is that for single replacing reaction, a metal replaces a metal and a non-metal replaces a non-metal. Single displacement reactions are characterised by one cation or anion trading place to form new products. Usually, when two compounds react, both cations or both anions will change partners, therefore, producing a double displacement reaction. The test that was conducted to demonstrate single displacement was practical number 4. Materials used to conduct the experiment was: magnesium, zinc, iron, copper, magnesium sulfate, zinc sulfate, iron (II) sulfate, copper sulfate, 16x100ml beaker, 20ml measuring cylinder and magnifying glasses. Six out of Sixteen solutions reacted. The reasoning behind this was because the element that replaced the original element needed to be more reactive. To give …show more content…
For example, cooking. When baking a cake, you can use simple ingredients such as baking soda (NaHCO3) reacts with acidic substances (HA). This can be written as the formula: NaHCO3 → HA → NaA + H(HCO3). Another example is a world landmark. The Statue of Liberty has outer layers that are made of copper, but the inner support is made of steel. When copper started to react to the air it formed a Verdigris coating (reasoning of why the statue is green), a single replacement reaction caused the iron to convert the copper back to copper metal; the iron started to rust and the entire inner support had to be replaced because of this in the
The question I was trying to answer is Which balanced chemical equation best represents the thermal decomposition of sodium bicarbonate. Using that question to guide us we were trying to determine which of the four chemical equations show how atoms are rearranged during thermal decomposition. We concluded it was the second chemical equation, we know that because:

A double replacement reaction, also called a double displacement reaction, is a type of chemical reaction in which two compounds react, and the anions and cations of the two reactants switch places to form two new compounds (products). A general equation for a double replacement reaction would be: AX + BY → AY + BX, along with any states of matter subscripted after each compound. Simply put, a double replacement reaction is the exchange of positive ions, or cations, between two compounds to form two new compounds. A precipitation reaction is a double replacement reaction in which two aqueous reactants
The equation shows how 1 mol of Na2CO3 reacts with 1 mol of H2SO4, so
Planning Firstly here is a list of equipment I used. Boiling tubes Weighing scales Knife Paper towels 100% solution 0% solution (distilled water) measuring beakers potato chips Cork borer. We planned to start our experiment by doing some preliminary work. We planned to set up our experiment in the following way.
Whilst doing the experiment there are many things that will have to remain the same in order to keep the tests fair, these include amounts and measurements as well as concentration and size and shape of the magnesium e.g. long strands. The temperature how ever will be the main change in the experiment, this is the only factor to change in less problems occur where a change is not optional. For each temperature the test will be taken three times to make sure that the results are correct and as accurate as possible, an average will be taken to give a clear and single result. A diagram of the apparatus I intend on using and how it will be assembled; [IMAGE] Safety- To ensure that the investigation is safe I will make sure that all equipment it correctly assembled, and I am wearing the appropriate safety wear and that everybody around is either dressed correctly or far enough away.
This will often be the case with ionic reactions but not always. Remember there is no magic trick that works all the time.
An elements¡¦ reaction to certain substances may be predicted by its placement on the Periodic Table of Elements. Across a period, an element on the left will react with more vigor than one on the right, of the same period. Vertically, as elements are sectioned into groups, the reaction of each element increases as you move down in the same group. With this in mind, the reactions of the substances involved in this experiment may be hypothesized, observed, and validated.
My goal in this experiment was to determine the amount of zinc (in grams) on 5 different galvanized nails to see if this specific box was up to standard, as well as how consistent the weight of the zinc is on each nail and do so by measuring the weight of the nail initially, then take the zinc off with the hydrochloric

Aim: The aim of this experiment was to determine the empirical formula of magnesium oxide.
Combination: These reactions combine elements to form a chemical compound, and within this oxidation and reduction occur together As usual, oxidation and reduction (redox) occur
Chemical kinetics is the study and examination of chemical reactions regarding re-arrangement of atoms, reaction rates, effect of various variables, and more. Chemical reaction rates, are the rates of change in amounts or concentrations of either products or reactants. Concentration of solutions, surface area, catalysts, temperature and the nature of reactants are all factors that can influence a rate of reaction. Increasing the concentration of a solution allows the rate of reaction to increase because highly concentrated solutions have more molecules and as a result the molecules collide faster. Surface area also affects a

Reactions occur when the particles of reactants collide together continuously. If they collide with sufficient energy, then they will react. The minimum amount of kinetic energy required for particles at the time of collision is called the activation energy and this theory is known as the ?collision theory?.
