Respuesta :

Answer:

A

Explanation:

Thats a physical change not a chemical change

Experiment 1  data should be changed to “No”. The conclusion on whether the process is a chemical reaction in the fourth column.

What is a chemical reaction ?

Chemical reaction deals  with the substances of  matter its composition and  the checking of their reactions and property is called as the chemical reaction .

The experiment is shown in the first column, the combination of substances in the second column,

The evidence of reaction in the third column, and the conclusion on whether the process is a chemical reaction in the fourth column.

The table correctly illustrates that the data indicates that the process is, in fact, a chemical reaction for the compounds in experiment 2, experiment 2, and experiment 3.

Gas formation, color change, and precipitate production are among the evidences. Such evidences point to the occurrence of chemical reactions.

Because they represent the production of a new substance (product) with a completely different chemical makeup than the reactants.

Nonetheless, the ingredients in the first row (experiment 1) comprise water and heat. The heat is not decomposing the water in this scenario. This means that the material,and,

Water, is the same before and, Hence, after heating since it has the same chemical makeup (H₂O).

Experiment 1 data should be changed to “No”.

Hence, option A is correct.
