show how to work it out... How many molecules of Mg3N2 (magnesium nitride) are formed when excess Mg (magnesium) reacts with 24.3 moles of N2 (nitrogen gas)? 3Mg(s) + N2(g) → Mg3N2(s) 43.1 molecules Mg3N2

Define the kinetic molecular theory

As changes in energy levels of electrons increase, the frequencies of atomic line spectra they emit

Two nails have identical sizes and shapes. in one nail, 20 percent of the domains are lined up. in the other nail, 80 percent of the domains are lined up. which has stronger magnetic force? first answer gets brainliest!
