Explanation:
such bad questions , how it could be around ???
The reaction between sulfuric acid, H2SO4 , and the base sodium hydroxide, NaOH , is a neutralization reaction. Na2SO4 is the salt sodium sulfate. ... For example, the reaction you've chosen is an acid-base reaction (also known as a neutralization reaction).
A potassium atom has a higher proton number meaning that it has more protons and electrons. Due to the Octet Rule, the more electrons an atom has the more shells it has and so will be bigger in size.

Answer:
1 × 10⁻² M
Explanation:
<em>What is the [H₃O⁺] in a solution with [OH⁻] = 1 × 10⁻¹² M?</em>
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
