Given the balanced equation:

2 ki + f2 --> 2 ki + i2

which type of chemical reaction does this equation represent?

In our case, the equation  2KI + F2 → 2 KI + I2 is a single-replacement (also called single- displacement) reaction.

Explanation:

Step 1: The balanced equation:

2KI + F2 → 2 KI + I2

Step 2: What kind of reaction

Since we start with 2 reactants and end with 2 products, we can say it won't be a synthesis or decomposition reaction.

In our case, It looks like it's a replacement reaction.

- A single-replacement reaction is a reaction in which one element replaces a similar element in a compound. The general form of a single-replacement reaction is:  A+BC→AC+B

where element  A  is a metal and replaces element  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.

- A double-replacement reaction is a reaction in which the positive and negative ions of two ionic compounds exchange places to form two new compounds. The general form of a double-replacement reaction is:  AB+CD→AD+BC

In our case, the equation  2KI + F2 → 2 KI + I2 is a single-replacement (also called single- displacement) reaction.
