Mg3N2 + Na → Na3N + Mg This is a reaction

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.

metric time was an attempt to create a standard unit of time based off of 10, but it never took off an is not included in the metric system (si)
