Answer 2

Equations of Reactions of Halogens with Barium (Ba):

When halogens react with barium (Ba), they form barium halides. The equations for the reactions of halogens with barium are as follows:

a) Chlorine (Cl2) with Barium (Ba): - Equation: Cl2 + Ba → BaCl2 - The compound formed is barium chloride (BaCl2) [[1]].

b) Bromine (Br2) with Barium (Ba): - Equation: Br2 + Ba → BaBr2 - The compound formed is barium bromide (BaBr2) [[2]].

c) Iodine (I2) with Barium (Ba): - Equation: I2 + Ba → BaI2 - The compound formed is barium iodide (BaI2) [[3]].

Equations of Reactions of Halogens with Zinc (Zn):

When halogens react with zinc (Zn), they form zinc halides. The equations for the reactions of halogens with zinc are as follows:

a) Chlorine (Cl2) with Zinc (Zn): - Equation: Cl2 + Zn → ZnCl2 - The compound formed is zinc chloride (ZnCl2) [[4]].

b) Bromine (Br2) with Zinc (Zn): - Equation: Br2 + Zn → ZnBr2 - The compound formed is zinc bromide (ZnBr2) [[5]].

c) Iodine (I2) with Zinc (Zn): - Equation: I2 + Zn → ZnI2 - The compound formed is zinc iodide (ZnI2) [[6]].

Equations of Reactions of Halogens with Aluminum (Al):

When halogens react with aluminum (Al), they form aluminum halides. The equations for the reactions of halogens with aluminum are as follows:

a) Chlorine (Cl2) with Aluminum (Al): - Equation: 2Cl2 + 2Al → 2AlCl3 - The compound formed is aluminum chloride (AlCl3) [[7]].

b) Bromine (Br2) with Aluminum (Al): - Equation: 3Br2 + 2Al → 2AlBr3 - The compound formed is aluminum bromide (AlBr3) [[8]].

c) Iodine (I2) with Aluminum (Al): - Equation: 3I2 + 2Al → 2AlI3 - The compound formed is aluminum iodide (AlI3) [[9]].

Equations of Reactions of Halogens with Silicon (Si):

When halogens react with silicon (Si), they form silicon halides. The equations for the reactions of halogens with silicon are as follows:

a) Chlorine (Cl2) with Silicon (Si): - Equation: Si + 2Cl2 → SiCl4 - The compound formed is silicon tetrachloride (SiCl4) [[10]].

b) Bromine (Br2) with Silicon (Si): - Equation: Si + 2Br2 → SiBr4 - The compound formed is silicon tetrabromide (SiBr4) [[11]].

c) Iodine (I2) with Silicon (Si): - Equation: Si + 2I2 → SiI4 - The compound formed is silicon tetraiodide (SiI4) [[12]].

Please note that the above equations represent the general reactions between halogens and the respective metals. The actual reaction conditions and stoichiometry may vary depending on the specific experimental setup.
