Metal oxides reacts with acids and form corresponding salt and water .The reaction is called ____________

• Neutralization reaction

• Acid - base reaction

Metal oxides which show both the properties of acids and base are called

• Amphoteric oxides

• Metamorphic

Sodium is kept in the oil in Lab .

• because it is highly reactive

• because its really soft

When sodium reacts with water it starts floating

• because hydrogen formed sticks to its surface and makes it less dense

• because it is less dense than water

Sodium and potassium are highly reactive .

• yes

• no

Nitric acid does not produce hydrogen gas when reacts with metals because

• its oxidising agent

• its reducing agent

sodium and potassium react vigorously with dilute hydrochloric acid . According to reactivity which metal will produce more bubbles with high temperature

• sodium

• potassium
