Ca + Cl2 ------------> Cacl2

The question is already balanced

Answer 2

Answer:

Steps (Algebraic Method)

Balance The Equation: Ca + Cl2 = CaCl2

1. Label Each Compound With a Variable

  aCa + bCl2 = cCaCl2

2. Create a System of Equations, One Per Element

  Ca: 1a + 0b = 1c

  Cl: 0a + 2b = 2c

3. Solve For All Variables

  a = 1

  b = 1

  c = 1

4. Substitute and Verify Result

  Ca + Cl2 = CaCl2

      L R

  Ca:1 1

  Cl: 2 2
