Please help, ty! 2 NH3(g) N2(g) + 3 H2(g)

At the same temperature as above, what would be the equilibrium constant (Kc) for the decomposition of ammonia?

there was no given temperature

ahhh​

Silica, sio2, is formed on silicon as an electrically insulating layer for microelectronic devices. silica is formed when silicon is exposed to o2 gas at an elevated temperature. at 900˚c, it takes 90 minutes for the oxygen to diffuse from the surface to form a 0.06 micron (0.06 x 10-6 m) thick layer of sio2 on

For each of the following compounds, decide whether the compound's solubility in aqueous solution changes with ph. if the solubility does change, pick the ph at which you'd expect the highest solubility. you'll find ksp data in the aleks data tab. compounds does solubility change with ph

Which change to the system wood cause the freely-moving piston to lower?
