$\text{Using the thermodynamic information in the ALEKS Data tab, calculate the standard reaction entropy of the following chemical reaction:}$ $\mathrm{Al}_{2} \mathrm{O}_{3}(\mathrm{s}) + 3 \mathrm{H}_{2}(\mathrm{g}) \rightarrow 2 \mathrm{Al}(\mathrm{s}) + 3 \mathrm{H}_{2} \mathrm{O}(\mathrm{g})$ $\text{Round your answer to zero decimal places.}$ $180 \frac{\mathrm{J}}{\mathrm{K}}$ $\square \times 10$
$\text{The user took a picture with their phone and the text was extracted above. The user then had a dialogue with an AI Assistant to help clarify the instructions.}$
$\text{Dialogue Transcript:}$
$\text{Assistant:}$ $\text{Hello! It looks like you need to calculate the standard reaction entropy for the given chemical reaction using thermodynamic data. However, there seems to be some missing information needed to proceed with the calculation, such as the standard entropy values for the reactants and products.}$
$\text{Could you please provide the standard entropy (S°) values for each substance involved in the reaction: Al₂O₃(s), H₂(g), Al(s), and H₂O(g)? Once you provide those values, I can help you calculate the standard reaction entropy.}$
$\text{User:}$ $\text{Al}_2\text{O}_3 = -321.7, \, \text{H}_2 = 130.7, \, \text{Al} = 28.3, \, \text{H}_2\text{O} = 188.8$

Problem 53981

For this week's discussion, you are asked to generate a continuous and differentiable function $f(x)$ with the following properties: - $f(x)$ is decreasing at $x=-6$ - $f(x)$ has a local minimum at $x=-3$ - $f(x)$ has a local maximum at $x=3$
Your classmates may have different criteria for their functions, so in your initial post in Brightspace be sure to list the criteria for your function.
Hints: - Use calculus! - Before specifying a function $f(x)$ , first determine requirements for its derivative $f^{\prime}(x)$ . For example, one of the requirements is that $f^{\prime}(-3)=0$ . - If you want to find a function $g(x)$ such that $g(-9)=0$ and $g(8)=0$ , then you could try $g(x)=(x+9)(x-8)$ . - If you have a possible function for $f^{\prime}(x)$ , then use the techniques in Indefinite Integrals this Module to try a possible $f(x)$ .
You can generate a plot of your function by clicking the plotting option (the page option with a "P" next to your function input). You may want to do this before clicking "How Did I Do?". Notice that the label " $f(x)=$ " is already provided for you.
Once you are ready to check your function, click "How Did I Do?" below (unlimited attempts). Please note that the bounds on the $x$ -axis go from -6 to 6 . It is recommended that you put a multiplication symbol between variables or between a variable and $\pi$ (should you use it). Example: Write $\sin (\pi \cdot x)$ instead of $\sin (\pi x)$ . $f(x)=$ $\square$

Problem 53984

Object 1 (mass=7.4 kg) traveling in the +x direction at a speed of 13.84m/s undergoes an inelastic collision with Object 2 (mass=6.10kg) which is at rest. Object two flies off at a speed of 9.95m/s and an angle $\theta_2 = 40.7^\circ$ . The diagram below is just a sketch and is not meant to have accurate angles. It is possible that Object 1 travels back and to the left, though it is not possible for it to travel in the -y direction. (Do you know why?)
What is the total momentum in x direction after the collision?
What is the momentum of Object 1 in the y direction after the collision?
What is the speed of Object 1 after the collision?
What is the angle $\theta_1$ in degrees? (Do not enter units)
