Explanation:

To solve this fill - in - the - blank problem about chemical equations and the law of conservation of mass, we analyze each blank based on the concepts of the law of conservation of mass and chemical equations:

Step 1: First blank (Law of what)

The law that deals with the mass of matter in chemical reactions is the law of conservation of mass. So the first blank is filled with "conservation".

Step 2: Second blank (Matter can or cannot be created)

According to the law of conservation of mass, matter cannot be created or destroyed in a chemical reaction. So the second blank is "cannot".

Step 3: Third blank (Matter can or cannot be destroyed)

As per the law of conservation of mass, matter also cannot be destroyed. So the third blank is "cannot".

Step 4: Fourth blank (Matter transformation in a reaction)

In a chemical reaction, matter is transformed from one state (or phase) to another. So the fourth blank is "transformed".

Step 5: Fifth blank (What a chemical equation shows)

A balanced chemical equation proves the law of conservation of mass. So the fifth blank is "balanced".

Step 6: Sixth blank (What the equation shows about atoms)

A balanced chemical equation shows the same amount of each atom on both the reactant and product sides. So the sixth blank is "same".

Step 7: Seventh blank (What to observe for atoms)

To observe the law of conservation of mass in a chemical reaction, we observe the atoms of each element. So the seventh blank is "atoms".

Step 8: Eighth blank (Where to observe - system type)

We observe the law of conservation of mass in a closed system (because in an open system, matter can enter or leave, which would affect the mass balance). So the eighth blank is "closed system".

Step 9: Ninth blank (What is conserved - products or reactants)

The mass of the products should be equal to the mass of the reactants in a closed system (due to the law of conservation of mass). So the ninth blank is "products".

The filled - in statements are:

The law of \(\boldsymbol{\text{conservation}}\) of mass states that matter \(\boldsymbol{\text{cannot}}\) be created nor \(\boldsymbol{\text{transformed}}\) from state to state (phase to phase); A \(\boldsymbol{\text{balanced}}\) chemical equation proves the law of conservation of mass as it shows the \(\boldsymbol{\text{same}}\) amount of an element in the reactants as in the \(\boldsymbol{\text{atoms}}\). It is best to observe in a \(\boldsymbol{\text{closed system}}\) as it will ensure the mass is the same at the beginning and end of a chemical reaction.
