Gizmo Warm-up

A chemical change. (or chemical reaction) occurs when one

or more substances, called reactants, are transformed into

different substances, or products. In the Chemical Changes

Gizmo, you will look for evidence of chemical changes by

looking at changes you can see, touch, or smell.

To begin, check that Reactant 1 is Sodium and Reactant 2

is Water. Sodium is a metal so soft you can cut it with a knife.

1. Click Play ( ). What do you observe?

2. Do you think a chemical reaction has taken place? Explain.

Respuesta :

Sodium hydroxide solution and hydrogen gas are produced from the reaction of water and sodium.

Reaction of sodium and water

We observe bubbles coming out of the water when the sodium reacts with the water because of the formation of hydrogen gas which is insoluble in water so it moves into the atmosphere.

Products of the reaction

Sodium metal reacts rapidly with water to form sodium hydroxide (NaOH) solution and hydrogen gas (H2). This chemical reaction is exothermic because huge amount of heat is release from the solution so we can conclude that sodium hydroxide solution and hydrogen gas are produced from the reaction of water and sodium.
