Question

types of reactions name each type of (unbalanced) reaction... a + b →→ ab a + xy →→ x + ay ab + xy →→ xb + ay

Explanation:

Step1: Analyze the first reaction \(A + B \to AB\)

In a combination reaction, two or more reactants combine to form a single product. Here \(A\) and \(B\) combine to form \(AB\).

Step2: Analyze the second reaction \(A+XY \to X + AY\)

In a single - replacement reaction, one element replaces another element in a compound. Here element \(A\) replaces element \(X\) in the compound \(XY\).

Step3: Analyze the third reaction \(AB + XY\to XB+AY\)

In a double - replacement reaction, the positive and negative ions of two ionic compounds exchange places. Here the ions in \(AB\) and \(XY\) exchange places to form \(XB\) and \(AY\).

Answer:

1. COMBINATION
2. SINGLE REPLACEMENT
3. DOUBLE REPLACEMENT
