Question

use the reactivity series to answer the question.
most reactive
potassium
sodium
calcium
magnesium
aluminium
zinc
iron
tin
lead
copper
silver
gold
least reactive
the non - metal carbon is between aluminium and zinc
the non - metal hydrogen is between lead and copper
in a replacement reaction, which metal would replace aluminum?
(1 point)
copper
zinc
sodium
gold

Explanation:

Step1: Understand the reactivity series

In a replacement reaction, a more reactive metal can replace a less reactive metal.

Step2: Compare the reactivity of given metals with aluminium

Looking at the reactivity series:

• Copper is below aluminium (less reactive than aluminium), so it cannot replace aluminium.
• Zinc is below aluminium (less reactive than aluminium), so it cannot replace aluminium.
• Sodium is above aluminium (more reactive than aluminium), so it can replace aluminium.
• Gold is below aluminium (less reactive than aluminium), so it cannot replace aluminium.

Answer:

C. sodium
