Answer 1

Answer #1

The most electropositive element reacts vigorously with water.

For calcium reacts slowly with water.

Carbon doesn't dissolve or react with water.

Potassium (K) reacts vigorously with water and gives metal oxides.

Zn doesn't react with water.

Si doesn't react with water.

So answer is K
