Final answer:
To determine the number of particles of HCl that reacted, we can use Avogadro's number to convert the given number of particles of H2O to moles. Since the balanced equation shows a 1:1 ratio between H2O and HCl, the number of moles of HCl will be the same as the number of moles of H2O.
Step-by-step explanation:
To determine the number of particles of HCl that reacted, we can use Avogadro's number to convert the given number of particles of H2O to moles. Since the balanced equation shows a 1:1 ratio between H2O and HCl, the number of moles of HCl will be the same as the number of moles of H2O. Using Avogadro's number, we can then calculate the number of particles of HCl.
Avogadro's number: 6.022 × 10^23 particles/mol
If 6.0 × 10^23 particles of H2O are produced, then there were 6.0 × 10^23 particles of HCl that reacted.
