For the reaction: N2(g) + O2(g) 2NO(g), the Keq at 2130°C is 0.0025. If [N2] = 0.75 M, [O2] = 0.30 M, and [NO] = 0.090 M, calculate Q and in which direction will the reaction shift? A.
3.6 × 10-2; shift to right
B.
3.6 × 10-2; shift to left
C.
4.0 × 10-1; shift to right
D.
4.0 × 10-1; shift to left

Particles vibrate in a rigid structure and do not move relative to their neighbors.

Skills of homo sapiens were found an excavation. the skulls were preserved because the bodies were frozen. so, these fossils are (blank) fossils. the image shows the evolution of skulls beginning 2 to 3 million years ago. based on the image, modern human skulls(blank) ape skulls.
