It occurs when gases such as nitrogen (N₂) come out of solution in the blood. This can lead to symptoms including joint pain, shortness of breath, and paralysis. Severe cases may result in death. a What type of molecule (ionic, polar covalent, nonpolar covalent) is nitrogen gas? b The liquid medium of blood is water. What type of compound (ionic, polar covalent, nonpolar covalent) is water? c What happens when molecules such as nitrogen gas mix with water? How does this explain the problems we see with decompression sickness?

Please don't copy I am completing an online lab so I will try to provide the needed information to solve. Please let me know if any information is missing. We started with 20 mL 1 M acetic acid ~ 0.020 L acetic acid in a flask. (Ka acetic acid = 1.8x10^-5; pKa = 4.7) (Kb ammonia = 1.8x10^-5; pKb = 4.7; Ka = 5.56x10^-10; pKa = 9.25) We titrated with 1 M Ammonia have to calculate the pH mathematically at different amounts of Ammonia added. Our Ammonia amounts are 8 mL, 16 mL, 20 mL, and 22 mL. We then have to find the percent difference of the online labs pH calculations. Online Lab's Values: 8 mL Ammonia - pH of 4.58 16 mL Ammonia - pH of 5.36 20 mL Ammonia - pH of 6.99 (equivalence point in the lab) 22 mL Ammonia - pH of 8.24 I would greatly appreciate if you could show for all 4 of the amounts of Ammonia added, and show how you did them. Thank you! Will gladly upvote if work is shown!

To complete the lab report, please answer the following questions. 1. Another way of testing for pH is to use pH paper. The pH paper is coated with a chemical that changes colors when immersed into the sample being tested. The color of the paper is then compared against a color chart that shows the colors associated with the different pH values. State one disadvantage of using pH paper instead of a pH meter. Answer: 2. The pH scale is a logarithmic scale. This means that the difference between each pH unit is really a factor of ten (in terms of actual magnitude of the acidity or basicity of the substance). If the pH of grapefruit juice is 3 (pH = 3), and the pH of beer is 5 (pH = 5), how many times more acidic is grapefruit juice than beer? Answer:

In reference to the MSDS for NaCl, how do we store NaCl?   https://fscimage.fishersci.com/msds/21105.htm     Store in a cool, dry place. Store in a tightly closed container.     Keep away from strong acids. Keep away from water.      Keep away from metals.      Keep away from flammable liquids. Keep away from organic halogens.
