Answer:
The representative particle for these elements is the molecule. Likewise, all molecular compounds such as H 2 O and CO 2 exist as molecules and so the molecule is their representative particle. For ionic compounds such as NaCl and Ca(NO 3 ) 2 , the representative particle is the formula unit.
Answer:
1) c Molecule
2) 6.02 x 10²³
Explanation:
1) The representative particle for these elements is the molecule. Likewise, all molecular compounds such as H 2 O and CO 2 exist as molecules and so the molecule is their representative particle. For ionic compounds such as NaCl and Ca(NO 3 ) 2 , the representative particle is the formula unit.
2) A mole of any substance contains Avogadro's number (6.02 × 10 23 ) of representative particles.
