Replacement reactions single

In this activity, you will use a few metals, their compounds, and dilute hydrochloric acid to show single-replacement reactions and construct an activity series. 

Use numbers to write balanced equations for single-replacement reactions. 

Single displacement (replacement) reactions are reactions in which atoms of an element replace the atoms of another element in a compound. All of these single replacement reactions are redox reactions, since the element (in a zero oxidation state) becomes an ion. Most single displacement reactions can be categorized into one of three types of reaction ... 

Predicting Use the diagram to predict if a single-replacement reaction will occur between the following reactants. Write a chemical equation for each reaction that will occur.

Applying Concepts Write a balanced chemical equation for the single-replacement reaction that occurred. 

The standard redox potential of the reaction CeS+ + 3e Ce is -2.2336 V. The metal undergoes single replacement reactions, displacing less electropositive metals from their salts in solution or melt ... 

Iron also exhibits single replacement reactions, precipitating less electropositive metals out of their salt solutions. Thus, sohd iron can reduce many metals, such as copper, silver, gold, mercury, tin and nickel ... 

Mercury dimethyl undergoes single replacement reactions with several metals such as alkali and alkaline earth metals, zinc, aluminum, tin, lead and bismuth forming their corresponding dialkyls. 

Violent reactions can occur with many metal hahdes. For example, with zinc halides or iron halides, single replacement reactions take place. Such potassium-metal halide mixtures can react violently when subjected to mechanical shock. 

In a single replacement reaction, one element replaces another element in a compound. An example of a single replacement is when sodium is added to water. The reaction of sodium and water is represented by the following chemical equation ... 

Simple Carbohydrate monosaccharides such as glucose, fructose, and galactose that cannot be broken down by water Single Replacement Reaction type of chemical reaction in which one element replaces another in a compound Smelting to melt an ore in order to refine a metal from the ore... 

In a single replacement reaction (sometimes referred to as a single displacement reaction), a single, more reactive element or group replaces a less reactive element or group, following the general pattern... 

Single replacement reactions in which metals replace other metals cire especially common. Not all single replacement reactions occur as written, though. You sometimes need to refer to a chart called the activity series to determine whether such a reaction will take place. 

Table 8-2 presents the activity series. To determine whether a single replacement reaction will occur, compare the two metals in the reaction ... 

Here are the completed, balanced versions of a series of single replacement reactions ... 

Zinc metal reacts spontaneously with an aqueous solution of copper sulfate when they re placed in direct contact. Zinc, being a more reactive metal than copper (it s higher on the activity series of metals presented in Chapter 8), displaces the copper ions in solution. The displaced copper deposits itself as pure copper metal on the surface of the dissolving zinc strip. At first, the reaction may appecir to be a simple single replacement reaction, but it s also a redox reaction. 

In a single displacement reaction, one element switches places with another element in a compound. The reactants in a single displacement reaction are an element and a compound, and the products are a different element and a different compound. A single displacement reaction can also be called a single replacement reaction. Look at this example of a single displacement reaction ...

As with any problem that includes the word react, the chance of needing a balanced chemical equation is pretty much a foregone conclusion. The single replacement reaction, written and balanced, is... 

Displacement. A displacement reaction (also called a single replacement reaction) occurs when an element reacts with a compound to form a new compound and release a different element. An example is the reaction that releases silicon (Si) from silicon dioxide (sand), Si02, via its reaction with carbon. Carbon monoxide, CO, is the reaction s other product. When further purified, the silicon can be used in computer chips.

These reactions are part of a larger category of reactions known as redox reactions (redox is short for oxidation-reduction). Sometimes these are called displacement reactions. These are chemical reactions in which atoms of one element replace the atoms of a second element in a compound. A general equation for a single-replacement reaction involving a metal (A), replacing a metallic cation in solution (B) is ... 

Redox reactions are not limited to single replacement reactions. They really describe a wide variety of reactions, but each shares the common theme of involving an oxidation and a reduction. An oxidation occurs when a substance loses electrons and becomes more positively charged. Earlier in the book we discussed a similar phenomenon in the formation of ionic compounds. Substances don t just lose electrons for no reason. They lose electrons because another substance takes them. When a substance acquires additional electrons and becomes more negatively charged, it is called a reduction. An oxidation cannot take place without a reduction, so these processes must occur simultaneously. These reactions describe the simultaneous oxidation and reduction of materials, which has earned them the name oxidation-reduction reactions. 

Fe3+ i Fe -e 3Fe2+. The reactants should tip you off that this has to be a single replacement reaction. This is a redox reaction, where iron is reduced. These are the only two possible oxidation states for iron. 

In this investigation, you will predict and observe a limiting reactant. You will use the single replacement reaction of aluminum with aqueous copper(II) chloride ... 

In a single replacement reaction, one element replaces one other element. 

The reaction of lithium and water is a single-replacement reaction. Lithium replaces a hydrogen in water, and the products of the reaction are aqueous lithium hydroxide and hydrogen gas. Lithium hydroxide exists as lithium and hydroxide ions in solution. 

In contrast to synthesis, combustion, and decomposition reactions, many chemical reactions involve the replacement of an element in a compound. There are two types of replacement reactions single-replacement reactions and double-replacement reactions. 

Single-replacement reactions Now that you ve seen how atoms and molecules rearrange in synthesis and combustion reactions, look closely at the reaction between lithium and water that is shown in Figure 10-8. The expanded view of the reaction at the molecular level shows that a lithium atom replaces one of the hydrogen atoms in a water molecule. The following chemical equation describes this activity. 

The reaction between lithium and water is one type of single-replacement reaction in which a metal replaces a hydrogen in a water molecule. Another type of single-replacement reaction occurs when one metal replaces another metal in a compound dissolved in water. For example. Figure 10-9 shows a single-replacement reaction occurring when a spiral of pure copper wire is placed in aqueous silver nitrate. The shiny crystals that are accumulating on the copper wire are the silver atoms that the copper atoms replaced. 

A metal will not always replace another metal in a compound dissolved in water. This is because metals differ in their reactivities. A metal s reactivity is its ability to react with another substance. In Figure 10-10 you see an activity series of some metals. This series orders metals by their reactivity with other metals. Single-replacement reactions like the one between copper and aqueous silver nitrate determine a metal s position on the list. The most active...
