A 2.0 mL sample of HCI(g) is mixed with a 1.5 mL of NH3(g). What is the volume if the resulting mixture after the reaction is complete? (Assume all measurements are carried out at the same pressure and temperature and that the volume of the solid is negligible) HCI(g) + NH3(g) —> NH4Cl(s)
A. 0.5 mL
B. 1.5 mL
C. 2.0 mL
D. 3.5 mL
