what equation shows the correct product and obeys conservation of mass for the reaction between barium and iodine? ba + i₂ → hint: remember to balance the charges. ba + i → bai 2ba + i₂ → 2bai ba + i₂ → bai₂

what equation shows the correct product and obeys conservation of mass for the reaction between barium and iodine? ba + i₂ → hint: remember to balance the charges. ba + i → bai 2ba + i₂ → 2bai ba + i₂ → bai₂

Answer

Explanation:

Step1: Determine the valency of elements

Barium (Ba) has a valency of +2 and iodine (I) has a valency of - 1. To form a neutral compound, one Ba²⁺ ion will combine with two I⁻ ions to form BaI₂.

Step2: Check mass - conservation

In the reaction Ba + I₂→, on the left - hand side, we have 1 Ba atom and 2 I atoms. On the right - hand side, in BaI₂, we also have 1 Ba atom and 2 I atoms, which satisfies the law of conservation of mass.

Answer:

Ba + I₂→BaI₂
