Classify and Balance the following reactions: 1. -Na+ldots Clarrow ldots NaCl 2. H_(2)O_(2)arrow H_(2)O+ldots O_(2) 3. -Cu+ldots Na_(2)SO_(4)arrow ldots Na+ldots CuSO_(4) 4. KI+ldots Ag(NO_(3))_(2)arrow ldots KNO_(3)+ldots AgI_(2)

## Step1: Identify the type of reaction and predict products if not given.### For 1, it's a synthesis reaction where sodium (Na) reacts with chlorine (Cl) to form sodium chloride (NaCl).### For 2, it's a decomposition reaction where hydrogen peroxide (H_2O_2) breaks down into water (H_2O) and oxygen (O_2).### For 3, it seems to be a typo but interpreting it as a single displacement reaction where sodium (Na) reacts with copper(II) sulfate (CuSO_4) to form sodium sulfate (Na_2SO_4) and copper (Cu).### For 4, it's a double displacement reaction where potassium iodide (KI) reacts with silver nitrate (AgNO_3) to form potassium nitrate (KNO_3) and silver iodide (AgI).## Step2: Balance the equations.### For 1, .### For 2, .### For 3, .### For 4, .
