It is inverse.
Fluorine will replace bromine to produce the compound lithium fluoride in a single replacement reaction.
A single replacement reaction will not occur. In a single replacement reaction, either a metal will replace another metal in a compound, or an anion will replace another anion in a compound. Click on the related link to see the Wikipedia article on single displacement (single replacement).
In general, acids react with metals in a replacement reaction, since metals can replace the hydrogen component of the acid. The more electropositive the metal is, and the stronger the acid it, the more energetic the reaction will be, and in the case of magnesium reacting with hydrochloric acid, we have a highly electropositive metal reacting with a very strong acid.
The activity series of metals goes something like this: Lithium Potassium Barium Calcium Sodium Magnesium Aluminum Zinc Iron Nickel Tin Lead Hydrogen Copper Mercury .............and so on..... ps, I might have left some elements out....can't remember them all... Since magnesium is higher in the reactivity series of metals, it can replace copper in a reaction. Copper is lower in the activity series of metals therefore can not replace magnesium.
There will be no reaction between the lithium and the potassium hydroxide. However, since the potassium hydroxide is in solution, the lithium will still react with the water to form lithium hydroxide and hydrogen gas. 2Li + H2O --> H2 + LiOH.
Fluorine will replace bromine to produce the compound lithium fluoride in a single replacement reaction.
During a chemical reaction, Magnesium can replace Aluminum due to a higher activity level.
Assuming you have a "+" sign in between the two reactants, this represents a single replacement reaction. They products will be Mg and Na2SO4.
A single replacement reaction will not occur. In a single replacement reaction, either a metal will replace another metal in a compound, or an anion will replace another anion in a compound. Click on the related link to see the Wikipedia article on single displacement (single replacement).
Magnesium is a more reactive metal than titanium and will replace the titanium in the titanium chloride. This kind of reaction is called a single replacement or single displacement reaction. 2Mg + TiCl4 --> Ti + 2MgCl2
In general, acids react with metals in a replacement reaction, since metals can replace the hydrogen component of the acid. The more electropositive the metal is, and the stronger the acid it, the more energetic the reaction will be, and in the case of magnesium reacting with hydrochloric acid, we have a highly electropositive metal reacting with a very strong acid.
Single Replacement Reaction.
Yes it is a chemical reaction, where 2 cations replace each other.
The activity series of metals goes something like this: Lithium Potassium Barium Calcium Sodium Magnesium Aluminum Zinc Iron Nickel Tin Lead Hydrogen Copper Mercury .............and so on..... ps, I might have left some elements out....can't remember them all... Since magnesium is higher in the reactivity series of metals, it can replace copper in a reaction. Copper is lower in the activity series of metals therefore can not replace magnesium.
In a single-replacment reaction, atoms of an element replace atoms of another element in a compound. In a double-replacement reaction, two positive ions trade places between different ionic compounds.
Cu + MgCl2 --> no reaction In order for a single replacement/displacement reaction to take place, the free metal must replace the bonded metal in the compound. However, according to the reactivity series of metals, copper does not replace magnesium, however magnesium would replace copper in a compound. Mg + CuCl2 --> Cu + MgCl2. Refer to the related link for a reactivity series of metals.
Although Calcium is lower on the activities series list I have seen calcium replace potassium in a reaction so the answer I think is YES
