What equation represents a single replacement reaction?

A single replacement reaction occurs when one element replaces another in a single compound. This type of reaction has the general equation: A + BC → B + AC. In this equation, A represents a more reactive element and BC represents the original compound.

Which equation represents a correctly balanced chemical equation?

Options (B) 3Fe (s) + 4H2O (g) → Fe3O4 (s) + 4H2 (g) – accurately represent a balanced chemical equation.

How do you do single replacement equations?

What is a single replacement reaction quizlet?

single-replacement reaction. a chemical change in which one element replaces a second element in a compound; also called a displacement reaction. activity series.

Which of the following correctly represents a balanced chemical equation Pb no3 2?

Balanced chemical equation for Pb (NO3)2 → PbO + NO2 + O. It is a decomposition reaction where a single type of chemical compound breaks down into two or more elements or new compounds.

Which of the following equations describes a synthesis reaction?

A synthesis reaction occurs when two or more reactants combine to form a single product. This type of reaction is represented by the general equation: A + B → AB. An example of a synthesis reaction is the combination of sodium (Na) and chlorine (Cl) to produce sodium chloride (NaCl).

Which one is a single replacement?

A single-replacement reaction is a chemical reaction in which one element replaces another in a compound. F₂ + 2NaCl → 2NaF + Cl₂, where F replaces Cl in NaCl. A double-replacement reaction is a reaction in which the metals in two ionic compounds exchange partners.

What is an example of a single displacement reaction quizlet?

What is always true of a single-displacement reaction? One element replaces another element in a compound. A piece of copper is placed into silver nitrate. … Copper will replace silver to form copper nitrate, because the activity of copper is greater than that of silver.

Are single replacement reactions redox?

Single-replacement reactions are redox reactions because two different elements appear as free element (oxidation number of zero) on one side of the equation and as part of a compound on the other side.

What is single replacement reaction with example?

A single-replacement reaction is a chemical reaction in which one element is substituted for another element in a compound, generating a new element and a new compound as products. For example, 2HCl(aq)+Zn(s)→ZnCl2(aq)+H2(g) is an example of a single-replacement reaction.

Which of the following is an example of a single replacement reaction?

Here are examples of single replacement reactions involving the cations: Zn(s) + 2 HCl(aq) → ZnCl2(aq) + H2(g) 2 K + 2H2O → 2 KOH + H2 (note how the anion is written differently because we don’t write water as HOH) Cu + 2 AgNO3 → 2 Ag + Cu(NO3)

How do you write a net ionic equation for a single replacement reaction?

How do you know which ion is replaced in a single replacement reaction?

To determine whether a given single replacement will occur, you must use an “Activity Series” table. If the metal or the halogen is above the element it will replace based on the activity series, a single displacement reaction will occur.

Which statement describes what happens during a single displacement reaction?

Which statement describes what happens during a single-displacement reaction? An atom or ion in a compound is replaced by another atom or ion.

What are examples of single displacement?

Examples of Single-Displacement Reactions

Cu, or copper, naturally occurs as a solid, so one of the products will be just Cu. Mg is in group 2, so it will have a charge of +2. SO4 can be treated as a single group of atoms, and the charge of SO4 is -2. The reaction will have the products Cu and MgSO4.

Is a single replacement reaction endothermic or exothermic?

Yes, single displacement reactions are exothermic.

What happens in a single replacement reaction apex?

What happens in a single-replacement reaction? A. Two reactants combine to form one product. … One reactant replaces an element in another reactant.

How do you determine a single displacement reaction?

Recognizing a Single-Displacement Reaction

You can predict whether a single-displacement reaction will occur by comparing the reactivity of an element using an activity series table. In general, a metal can displace any metal lower in the activity series (cations). The same rule applies to halogens (anions).

Why is single replacement reaction exothermic?

A single-displacement reaction is a chemical reaction that occurs when one element in a molecule is replaced by another. … The reaction is exothermic if energy is released. The creation of bonds is an exothermic reaction. Because the atoms are moving to a lower energy state, energy is released.

Do single replacement reactions produce heat?

a single replacement reaction, the solution turns blue, and silver crystals form on the wire. replacement reaction that produces hydrogen gas and potassium hydroxide. The heat produced by this chemical reaction causes the hydrogen gas to ignite explosively.

Is a precipitation reaction endothermic or exothermic?

Precipitation reactions can be either endothermic and exothermic. It is more than clear that all precipitations are not exothermic. Also definitely noticable is the fact that ΔS is a positive quantity.
