single replacement occurs when they is an obvious difference in reactivity for both your metals. reactivity is determined by the number of electrons that must be transferred to a nonmetal. metals with only 1 outer shell electron will be more reactive than metals with two or more electrons. If you got Rubidium and Sodium obviously rubidium got the better reactivity, it will replace any sodium compound in any reaction unless u got something more reactive than rubidium.
for such reactions we consider the electrochemical series. it is a series of metals that help us determine which metal can replace other metal. by conventions a metal can replace all the metals that are above 8 in the electrochemial series.
The ability to replace another metal determines a metal's reactivity. The activity series of metals is a scheme that places the metals in order of reactivity. A metal can replace another metal if it appears above the metal in an activity series.
A single replacement reaction is a reaction where a single uncombined element replaces another in a compound. Not all elements can be replaced during this reaction. This displacement occurs when there's a difference in reactivity for both metals. Reactivity is always determined by how many electrons that are needed to be transferred to become a nonmetal. For example if you have magnesium, zinc, aluminum and lithium you couldn't replace lithium for magnesium b/c there wouldn't be any type of reaction.
In order for one metal to displace another in this type of reaction depends on the reactivities of the two metals. Reactivity is determined by the transfer of electrons to a nonmetal.
Mohammad, I didn't understand your response, "by conventions a metal can replace all the metals that are above 8 in the electrochemial series" Explain in detail what is electrochemical series, how does this series help in determination of reactivity of elements?
My answer ties in with Muhammad's. The way to determine whether one metal will replace another metal in a single-replacement reaction is by electrochemical series. This series is also known as electromotive series. It lists metals and other substances in order of decreasing activity, meaning, the more reactive the substance is, the higher it would be above all other substances. The stable or "noble" gases are at the bottom. By looking at the electrochemical series, you find which metal is more reactive, and would react with another substance instead of the other metal.
Reactivity in metals is what determines whether one metal will replace another metal from a compound in a single-replacement reaction. I believe if one metal is a bit more reactive than another metal it will replace it. Take for instance you have a metal with a low reactivity and a metal with a high reactivity, the metal with the high reactivity will replace the low reactivity metal.
When a metal can replace another metal it depends on the other metals reactivity. It is callled the activity series of metals.It put the metals in order in its reactivity.The only way a metal can a metal can replace another metal if it is above the metal that it is replaceing in an activity series.
Replacement occurs when there is an obvious difference in reactivity for both the metals.For example if you got Rubidium and Sodium, obviously rubidium got the better reactivity, and it will displace any sodium compound in any reaction unless u got something more reactive than rubidium.
the activity series determines whether or not a metal will replace another one in a replacement reaction. Not all single replacement reactions can occur. Before writing the products for any single replacement equation, must check the activity series to see if the replacement is possible.
single replacement reaction is a chemical reaction where one element replaces another element in a compound to increase stability. it is sometimes known as single displacement reaction.The activity series of metals is a scheme that places the metals in order of reactivity. A metal can replace another metal if it appears above the metal in an activity series. this is what determines whether or not a metal may be replaced in a reaction.
As said before, single replacement is a reaction in which one element replaces another element in the given compound which ties into the activity series. The activity series will determine if a metal will replace another metal. There's a chart that lists the elements and how strong they are compared to other elements and it gives info on whether they are reactive or not.
to determine whether a metal will replace another metal is by using the activity series. by using this, you can determine the weakness of a metal and replace it with another metal in single replacemnt.
What determines whether one metal will replace the other is the activity series. An activity series is a list of elements organized according to the ease with whihc the elements undergo certain chemical reactions. For example: Ca(s) + H2O(l) →CaO+ H2. Calcium would replace hydrogen because it is more reactive than hydrogen.

ReplyDeleteDenzel, Rubidium and Sodium belongs to same group and have one valence electron. In such situation, how can we determine the replacement?

ReplyDeleteJasmine, you mean metals become non metals by losing electrons?
