Zn

100

What is oxidation in a redox reaction?

Loss of electrons

150

What is a displacement reaction?

A displacement reaction is a chemical reaction in which a more reactive element displaces a less reactive element from its compound

200

In the reaction Fe₂O₃+3CO→2Fe+3CO₂, which substance is oxidized and which is reduced?

7

100

What products are formed when sulfuric acid reacts with potassium hydroxide?

potassium sulfate

150

What is the chemical formula for nitric acid?

HNO₃

200

What is the net ionic equation for neutralization reaction?

H⁺(aq)+OH⁻(aq)→H₂O(l)

250

Explain why all alkalis are bases, but not all bases are alkalis.

Alkalis are soluble bases, but only some bases are soluble in water, so these are not alkalis.

Reactivity Series

50

What happens to the reactivity of metals as you move down Group 1 in the periodic table?

It increases

100

In the reaction: Fe + CuSO₄ → FeSO₄ + Cu, which metal is displaced?

Copper-Cu

150

 If magnesium reacts with zinc sulfate, what will be the products?

Magnesium sulfate + zinc

200

Explain why copper cannot displace zinc from zinc sulfate solution.

Copper cannot displace zinc from zinc sulfate solution because copper is less reactive than zinc.
