In an experiment, 3.00 mol of iodine gas and 3.00 mol of chlorine gas are initially placed into a 4.00 L container at 225°C. Construct an ICE table and find the concentrations of all reactants and products at equilibrium.  

I2 (g) + Cl2 (g) ⇌ 2 ICl (g) K = 44.6 at 225°C

In a FRAP experiment using fluorescent antibodies against a cell surface protein, the region of interest that was bleached did not show fluorescence recovery after 30 seconds but did show recovery after 150 seconds. What does this tell you about the mobility of the cell surface protein? (2 points)

Calculate the weight % of acetic acid in the vinegar. Calculate your percent error. For this calculation, assume that the density of vinegar is 1.01g/mL.

0.8488 Molarity of acetic acid in my experiment.

I'm a little confused-if you solve it can you be sure to specify what the conversion factors are in the calculations. Thank you!

Your neurobiology lab primarily studies gene expression of distinct brain regions to better understand mechanisms behind memory loss. Your task as a new graduate student is to create libraries of Olfactory Bulb and Hippocampus rat brain regions. Propose an experiment (simple steps, flow chart...) to accomplish this.

Two 6-sided dice are rolled. One die is a standard die, and the other is a Fibonacci die with sides 1, 1, 2, 3, 5, and 8.

a. What is the probability distribution of this experiment?

b. What is the shape of the probability distribution?

c. What is the expected value when these 2 dice are rolled?

Different states and counties are in the process of relaxing non-pharmaceutical interventions (i.e. social distancing) for the COVID-19 response. Please explain how you would setup a natural experiment to measure the effectiveness of different non-pharmaceutical interventions. Please write a hypothesis and how you would test the hypothesis.

There is double-slit experiment of slit spacing d and apart from the screen as L. Let’s think about the mth bright fringe. Here m is positive integer. Then expand the distance between the slit and screen as ? + ∆?. Find the phase different between the mth bright fringes at the original screen and expanded screen.

In an acid-base titration experiment, 50 mL of a 0.05 M solution of acetic acid (Ka = 1.75 x 10-5 ) was titrated with a 0.05M solution of NaOH at 25 oC. The system will acquire this pH after addition of 40 mL of the titrant:

Answer: 5.36

How do you solve this?

1. Design either a randomized controlled double blind experiment on a particular study of interest OR design a matched pairs study. State how you have been able to eliminate bias in your study.

Be highly specific in your answer. Your answer must be at least 8 COMPLETE sentences in length.
