Answer:
1.5 moles of H₂SO₄ needs 3.0 moles pf KOH to be neutralized.
Explanation:
- KOH is dissociate according to the equation:
KOH → K⁺ + OH⁻.
- H₂SO₄ is dissociated according to the equation:
H₂SO₄ → 2H⁺ + SO₄²⁻.
<em>So, every 1.0 mole of KOH produces 1.0 mol of OH⁻.</em>
<em>While, every 1.0 mole of H₂SO₄ produces 1.0 mol of H⁺.</em>
<em />
Thus, every mol of H₂SO₄ needs 2.0 moles of KOH to be neutralized.
<em>So, 1.5 moles of H₂SO₄ needs (2 x 1.5 mol) = 3.0 moles pf KOH to be neutralized.</em>
A cell is made of molecules and a molecule is made of atoms. That's the simplest way of putting it. More complicated is that a cell is made up of macromolecules, such as proteins, lipids, etc. A molecule is a particular configuration of atoms.
