Question

In the chemical reaction below, all three chemicals are best classified as:

NaCl2O3 → NaCl + CIO2

a. three compounds
b. three elements
c. one element and two compounds one compound and two elements​

Answer 1

All substances in the provided chemical reaction, NaCl2O3, NaCl, and CIO2, are compounds, as each is made up of two or more elements chemically joined. Therefore, the answer is 'a. three compounds'.

Step-by-step explanation:

In the chemical reaction provided, NaCl2O3 breaks down into NaCl and CIO2. All substances involved can be classified correctly as compounds since each one is comprised of two or more elements chemically combined in fixed proportions. Let's analyze the substances involved:

• NaCl2O3: This is a compound comprised of sodium, chlorine, and oxygen.
• NaCl: Known as sodium chloride, this is a binary compound made up of sodium and chlorine.
• CIO2: This is chlorine dioxide, another compound consisting of chlorine and oxygen.

No single elements are present in the given reaction as reactants or products; everything exists as compounds. Therefore, the answer to the student's question is a. three compounds.
