Question

Salt has the chemical formula NaCl because it is made up of atoms of Sodium (Na) and Chlorine (Cl). Which statement most accurately describes this compound in relation to the elements it is made of?

A. When sodium and chlorine chemically combine, they create a substance with completely different properties

B. Salt has similar properties to the sodium and chlorine it is made of

C. Once salt is formed the sodium and chlorine atoms no longer exist, only salt atoms

D. Salt can easily be separated back into sodium and chlorine atoms through physical means

Answer 1

A. When sodium and chlorine chemically combine, they create a substance with completely different properties

Step-by-step explanation:

B. Salt has similar properties to the sodium and chlorine it is made of

- Chemical compounds (salt) have different chemical properties than the elements (Na and Cl) are made out of.

C. Once salt is formed the sodium and chlorine atoms no longer exist, only salt atoms

- there is no such thing as salt atoms the atoms still exists in order to form the compound

D. Salt can easily be separated back into sodium and chlorine atoms through physical means

- chemical compounds can only be separated by chemical means
