Answer:
Equation 2, because Fe is being more reactive, replaces Cu from CuSO₄.
Explanation:
- Equation 1 is: <em>CuSO₄ + 2NaOH → Na₂SO₄ + Cu(OH)₂.</em>
The reaction between CuSO₄ and NaOH will give Na₂SO₄ and Cu(OH)₂ which is a precipitate "replacement reaction".
- While, equation 2 is: <em>CuSO₄ + Fe → Cu + FeSO₄.</em>
The reaction between CuSO₄ and Fe will produce Cu and FeSO₄.
Thus, it is used to extract Cu because Fe is more reactive than Cu, so it can replace it in its salts and Cu can be extracted.
- <em>So, the right choice is: Equation 2, because Fe is being more reactive, replaces Cu from CuSO₄.</em>

Explanation:
<em>Glucose and galactose are monosaccharides that differ from one another only at position C-4. Thus, they are epimers that have an identical configuration in all the positions except in position C-4. ... Glucose and galactose are epimers that do not differ in position C-5 but differ in position C-4.</em>
