Una masa de hidrogeno H2 ocupa un volumen de 12 litros a 730 mmHg. ¿Cuál es el volumen del gas a 1200 mmHg, si la temperatura permanece constante?

Consider the reaction: n2(g) + o2(g) ? 2no(g) kc = 0.10 at 2000oc starting with initial concentrations of 0.040 mol/l of n2 and 0.040 mol/l of o2, calculate the equilibrium concentration of no in mol/l how would this be done?

Compare and contrast physical changes with chemical changes.

How many liters of oxygen gas, at standardtemperature and pressure, will react with 35.8 grams ofiron metal? 4 fe (s) + 3 o2 (g) → 2 fe2o3 (s)
