Emissions from a gas tank + Raoult's law. Consider a mixture of 25% ethanol (or ethyl alcohol, C₂H₆O) and 75% toluene (C₇H₈) by volume in an enclosed tank. The volume of the tank is 10 m³ and it is currently 10% full of the liquid mixture (i.e., the volume of the liquid is 1 m³). Assume the tank is kept at atmospheric pressure (P = 1 atm). a. The vapor pressure of ethanol is 1.5x10⁻²atm, and the vapor pressure of toluene is 8.8x10⁻³ Which chemical (ethanol or toluene) more likely to be in the gas phase at a given temperature and pressure • Calculate the mass of ethanol and toluene in the gas and liquid phases in [grams]. Assume a constant density in liquid phase of 0.67 g/cm³. A useful value of the universal gas constant R here is 8.205 x 10⁻⁵m³ atm K⁻¹ mol⁻¹. Enter your results in the table. Ethanol; M = 46 g / mol Toluene; M = 92 g / mol Liquid phase Gas phase Assume the tank, which was originally only 10% full of liquid, is then filled with the liquid mixture to 95% of the tank volume. What are the emissions of ethanol and toluene in [grams] vented from the tank? 1. ethanol: _______ g 2. toluene: _______ g

I need help creating a consistent and evenly timed string. The string is 500 cm/ 5 meters. I want to use at least 6 bolts but at most 10 bolts. I don’t want an evenly spaced string, I want it to span across the 500 cm. I also want the difference of the differences to equal 0. Essentially I want the rate of change of velocity with respect to time to be consistent. PLEASE HELP!

A child who weighs 250 N sits on a sled that weighs 50 N. His mother pushes the sled to give it an initial speed of 1 m/s at point A. The coefficient of sliding friction between the sled and the snow is $\mu_k = 0.15$. Determine the distance ABC the sled slides before it comes to rest. What is the maximum speed the sled attains?

Can someone please help me plot two line graphs from the chart above? The first line graph is for t (average time) vs. √d for the steel ball. The second is a line graph of t (average time) vs. √d for the hollow plastic ball. Also, can you include the slopes for both graphs? Thank you so much! I will rate you good if you help make these two graphs! Equipment Use: 1) Make sure the magnetic drop box is above the target pad. 2) Set the control box switch to arm. 3) Turn on the smart timer. 4) Press the "select measurement" button until time appears. 5) Press the "select mode" button until two gates appear. 6) Press the stop/start button once. 7) Press the button to release the object. 8) Record the time. 9) Press start/stop to reset the timer (green light will turn on when ready for the next trial).
