Answer

Explanation:

Step1: Identify coefficient and sub - scripts for 3MgCl₂

The coefficient is the number in front of the chemical formula, which is 3. The sub - script for Mg is 1 (when no sub - script is written, it is 1), and the sub - script for Cl is 2.

Step2: Identify coefficient and sub - scripts for V₂O₅

There is no number in front, so the coefficient is 1. The sub - script for V is 2 and for O is 5.

Step3: Identify coefficient and sub - scripts for 4K₂CO₃

The coefficient is 4. The sub - script for K is 2, for C is 1, and for O is 3.

Step4: Identify coefficient and sub - scripts for NaC₂H₃O₂

There is no number in front, so the coefficient is 1. The sub - script for Na is 1, for C is 2, for H is 3, and for O is 2.

Answer:

  1. coefficient: 3, subscript for Mg: 1, subscript for Cl: 2
  2. coefficient: 1, subscript for V: 2, subscript for O: 5
  3. coefficient: 4, subscript for K: 2, subscript for C: 1, subscript for O: 3
  4. coefficient: 1, subscript for Na: 1, subscript for C: 2, subscript for H: 3, subscript for O: 2
