A mixture containing only Al$_2$O$_3$ (FM 101.96) and Fe$_2$O$_3$ (FM 159.69) weighs 2.019 g. When heated under a stream of H2, Al2O3 is unchanged, but Fe$_2$O$_3$ is converted into metallic Fe plus H$_2$O(g). If the residue weighs 1.774 g, what is the weight percent of Fe$_2$O$_3$ in the original mixture?

Determine equilibrium values for the given dynamical systems and state whether these equilibrium values are stable. a) $A_{n+1}=3 A_n-1$ b) $B_{n+1}=0.5 B_n-3$

A mixture of nuts contains 1 cup of walnuts for every 3 cups of peanuts.

Write a linear equation that represents the relationship between peanuts, x, and walnuts, y.

Classify substance Cytosine, a component of DNA, consists of H, C, N, and O atoms bonded in a specific arrangement, as an element, compound, or mixture, and explain your answer.

A frame in the shape of the simple scissors truss shown at the right below can be used to support a peaked roof. The weight of the roof compresses some parts of the frame (green), while other parts are in tension (blue). A frame made with $s$ segments joined at $j$ points is stable if $s \geq 2 j-3$. In the truss shown, 9 segments connect 6 points. Verify that the truss is stable. Then find the values of $x$ and $y$.

Each molecular-scale scene below represents a mixture. Describe each one in terms of the number of elements and/or compounds present.

Draw a reaction coordinate diagram for the following reaction in which C is the most stable and B the least stable of the three species and the transition state going from A to B is more stable than the transition state going from B to C:

a. How many intermediates are there?

b. How many transition states are there?

c. Which step has the greater rate constant in the forward direction?

d. Which step has the greater rate constant in the reverse direction?

e. Of the four steps, which has the greatest rate constant?

f. Which is the rate-determining step in the forward direction?

g. Which is the rate-determining step in the reverse direction?
