Determine the percent yield for the reaction between 30.2 grams of NH3 and excess oxygen to produce 20.1 grams of NO gas and water. 4NH3 (g) + 5O2 (g) → 4NO (g) + 6H2O (g)

The diagram shows the structures of horse and cat forelimbs. what does the diagram suggest about the evolutionary relationship between these two mammals? a. they have homologous structures, indicating a common ancestor. b. they have analogous structures, indicating a common ancestor. c. they have homologous structures, indicating that they do not have a common ancestor. d. they have analogous structures, indicating that they do not have a common ancestor.

What’s the percent by mass of carbon in c10h14n2

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?
