Consider the equations below. (1) Fe2O3(s) - 2Fe(s) + CO2(g) 2 ) (2) Fe2O3(s) + 3CO(g) - 2Fe(s)+3CO2(g) Which equation must be added to equation (1) to produce equation (2)? CO(g) + O2(g) = C020) 3CO2(g) → 300[g)+302(0) g (+ 3CO( 300(g)+202/9) >3002(0) 3 of 8 w A RL

The isotonic saline solution described in part a is connected to an unknown solution via a semipermeable membrane, the unknown solution level drops. based on this information, what can be said about these two solutions?

What if it is did darwin used to support his theory of evolution

Asubstance is held in an open container. its particles move past one another at random speeds but do not leave the container. heat is removed from the system, and the particles slow down. when enough heat is removed, the particles no longer have enough speed to overcome the weak attractive forces between them. when this happens, the substance enters its solid state. the process described above is known as .
