What is single-replacement reaction with example?
An example of a single replacement reaction occurs when potassium (K) reacts with water (H2O). A colorless solid compound named potassium hydroxide (KOH) forms, and hydrogen gas (H2) is set free. The equation for the reaction is: 2K + 2H2O → 2KOH + H.
What is the general equation for a double-replacement reaction?
Summary. The double-replacement reaction generally takes the form of AB + CD → AD + CB where A and C are positively-charged cations, while B and D are negatively-charged anions.
What is the equation of displacement reaction?
A single-displacement reaction, is a chemical reaction in which one element is replaced by another in a compound. It can be represented generically as: A + B-C → A-C + B.
What is the equation for the breakdown of hydrogen peroxide?
Q: What is the chemical equation for the decomposition of hydrogen peroxide (H2O2) to water (H2O) and oxygen (O2)? A: The equation for this decomposition reaction is: 2 H2O2 → 2 H2O + O.
Which equation best represents a single displacement reaction?
In a single-displacement reaction, one element displaces another element in a compound. The general equation for a single-displacement reaction is: A + B-C → A-C + B A and B must be either different metals (including H) or different halogens. Chemists have devised an Activity Series.
How do you balance a single replacement reaction?
You balance the equation for a single replacement reaction the same way as any other equation. You place coefficients in front of the chemical formulas so that the numbers of atoms of the elements are the same on both sides.
How do you recognize a single replacement reaction?
Recognize the general formula for single replacement. A single replacement reaction occurs when one element replaces another element within a compound. It generally takes the form of AX + Y –> YX + A or A + XY –> XA + Y. One reactant is always a single element and the other reactant is always a compound.
Which equation is a double replacement reaction?
A double replacement reaction is a chemical reaction where two reactant ionic compounds exchange ions to form two new product compounds with the same ions. Double replacement reactions take the form: A+B- + C+D- → A+D- + C+B-.
