Explanation:

What is the [H₃O⁺] in a solution with [OH⁻] = 1 × 10⁻¹² M?

Step 1: Given data

Hydroxile ion concentration ([OH⁻]): 1 × 10⁻¹² M

Step 2: Calculate the concentration of the hydronium ion

Let's consider the self-dissociation of water.

2 H₂O(l) ⇄ H₃O⁺(aq) + OH⁻(aq)

We can calculate the concentration of the hydronium ion using the ion product of water.

Kw = 10⁻¹⁴ = [H₃O⁺] [OH⁻]

[H₃O⁺] = 10⁻¹⁴ / [OH⁻] = 10⁻¹⁴ / 1 × 10⁻¹² = 1 × 10⁻² M

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
