The model on the right looks bumpy, but when you break a large salt crystal in two, the edges of the split often look straight and feel smooth. Is there a problem with the model? Use what you have learned about atoms to explain.

that's what i got you can count the number of atoms

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.
