a 9.85 g sample of an unknown metal M is burned in the presence of excess oxygen, producing the oxide M2O3 (s) and liberating 57.8kJ of heat at constant pressure. What is the identity of the metal? 4M(s) + 3O2(g) yields 2M2O3(s)
Let f(x) = 1/(x+2) and g(x)= (x-1)/x. Simplify and state the domain. f(g(x)) g(f(x))
so the correct answers for this quick check, which I just took, are: 1. b 2. c 3. a 4. d
4 is d
