Question

in a synthesis reaction, two atoms of sodium (na) combine with one molecule of chlorine gas (cl₂) to produce sodium chloride (nacl). how many molecules of sodium chloride are produced? (1 point) three one two four

Explanation:

Step1: Write the chemical equation

$2Na + Cl_{2}
ightarrow 2NaCl$

Step2: Analyze the stoichiometry

From the equation, 2 moles of Na and 1 mole of $Cl_{2}$ produce 2 moles of NaCl. Since the mole - to - molecule conversion factor is based on Avogadro's number, the number of molecules of a substance is proportional to its number of moles. So, 2 molecules of sodium react with 1 molecule of chlorine gas to produce 2 molecules of sodium chloride.

Answer:

C. two
