To begin, check that the Reactant 1 is Sodium and Reactant 2 is Water. Sodium is a metal so soft you can cut it with a knife. What do you observe?

 

Here, reactant 1 is sodium and reactant 2 is water, the observation made are as follows;

1. A colorless solution is form.

2. A fizz sound and burning with a orange flame is observed.

EXPLANATION : The explanation for above observation is given below;

1. When sodium reacts with water a very alkaline solution of sodium hydroxide is formed which is colourless.

2. Sodium + water is a exothermic reaction, sodium reacts with water harshly releasing heat energy.
