sodium , potassium , calcium , aluminium , zinc magnesium using these metals write the reaction with water , oxygen and with acids
Answers
Answer:
Carbon is having less affinity for oxygen and also it is a weaker reducing agent than these metals. Reducing agents are the elements that can donate electrons and itself gets oxidized. Carbon does not electrons. Metals donate electrons easily whereas non metals accepts electrons easily.

Sodium and potassium metals react violently with cold water.
Observations :
1. Metal starts moving over the surface of the water making a hissing sound.
2. Metal starts reacting with water causing little explosion
3. Soon the metal catches fire and starts burning.
Reaction:
2K+2H
2
O→2KOH+H
2
2Na+2H
2
O→2NaOH+H

The gas evolved during the reaction can be identified bringing a burning candle near it. The candle burns with a pop sound indicating the evolution of hydrogen gas.
