What is the equation for a single replacement reaction?
Dec 3, 2020 · Here are examples of single replacement reactions involving the cations: Zn (s) + 2 HCl (aq) → ZnCl 2 (aq) + H 2 (g) 2 K + 2H 2 O → 2 KOH + H 2 (note how the anion is written differently because we don’t write water as HOH) Cu + 2 AgNO 3 → 2 Ag + Cu (NO 3) 2. Ca + 2 H 2 O → Ca (OH) 2 + H 2.
Once we know which elements might get swapped in our single displacement reaction, we can predict whether the reaction will occur based on knowledge of the relative reactivities of the two elements—elements C and A in the generic pattern above, or copper and silver in our example reaction.
- In problem 1, why is the correct answer NaCl(aq)+Br2? what happened to the second Cl? did it just...Bromine forms a diatomic molecule when it is by itself. Hence the Br2 and not 2Br.
- In Problem 2, why Zinc as opposed to Silver?Silver is below copper in the activity series, so it will not displace copper. Zinc is above copper, so it will displace copper.
- How do we know Mg has +3 charge and PO4 has - 3 charge? Explain it to me.mg is +2 the electronic configuration is 2,8,2. To achieve octet state it gives 2 electrons . Now it has 2 more protons so the overall charge is +2...
- What is the difference between a single replacement and a double replacement reaction?A *single-replacement reaction* is a chemical reaction in which one element replaces another in a compound. The general equation is A + BC → AC + B...
- Are the products of single replacement reactions related to the electronegativities of the elements ...I was also wondering the same question, and I googled out this aritle. http://www.madsci.org/posts/archives/1999-09/936330555.Ch.r.html
- 2AgNO3(aq)+Cu(s)→Cu(NO3)2(aq)+2Ag(s) In this formula, how do we know that copper has a +2 charge ?You can't really know it other than memorising. Cu2+ is generally more stable than Cu+.
- what will happen if the element reacting with a compound is less reactive then the element present i...reaction would not occur. in example, compound with magnesium is more stable than compound with aluminum so phosphate tends to keep bonding with ma...
- So I have to ignore Zn + 2 H2O = Zn(OH)2 + H2 in the aqueous solution here? I don't understand why I...The reaction CuSO4 + AgNO3 would not be a single replacement reaction since the reactants are both compounds, i.e. there are no pure elements. Also...
- Why is it Cu 2+, but Ag +? They are in the same column and nowhere does it say thatTransition metals have variable valencies. So, transition metals in the same column might have different valencies.
A + BC → AC + B A + BC → AC + B. In this general reaction, element A A is a metal and replaces element B B (also a metal) in the compound. When the element that is doing the replacing is a nonmetal, it must replace another nonmetal in a compound, and the general equation becomes: Y + XZ → XY + Z Y + XZ → XY + Z.
Examples of Single-replacement Reaction. An example of a single-displacement reaction occurs when potassium (K) reacts with water (H 2 O). A colorless solid compound named potassium hydroxide (KOH) forms and hydrogen gas (H 2) is set free. The equation for the reaction is:
Single-replacement reactions are reactions in which one element replaces another in a compound. Example: AX + B → A + BX. Single replacement reactions are typically exothermic reactions due to the formation of a new bond in the products.
A single replacement reaction occurs when an element reacts with a compound to produce a new element and a new compound. There are two types of single replacement reactions: A metal replaces another metal that is in solution: #"A" + "BC" → "B" + "AC"#. Example: #"Zn" + "CuCl"_2→ "Cu" + "ZnCl"_2#.
Here are several examples which are solved below: 1) ZnS + O 2 ---> 2) K + H 2 O ---> 3) Fe + HCl ---> 4) NaI + Br 2 ---> Example #1. How to figure out the right (or product side): (1) Decide if the reactant element (O 2 in this case) is normally positive or negative. (It is a negative 2. Just use O, not O 2 .)
