- How does acidic water affect the mass of a shell ? Can you provide alot of evindenceMobile phase can be : A) Solid or liquid B) Only solid C) Only gas D) Liquid or gasA team of investigators is out on a boat on a lake on a marvelous,sunny summer day, and they are taking water samples fromvarious depths in the lake so as to construct a plot of dissolvedO2 concentration versus depth, similar to the plot in Figure 1.16.When the investigators bring up a water sample from a depthof 20 m, why is it imperative that they measure its dissolved O2concentration immediately, rather than letting it sit on the deckfor 5 minutes? (Hint: Look at Figure 22.2A.

How much stock solution and how much water should I add to acheive this?Prepare 1L 20X Trace minerals stock in a media bottle: Fill out the last column of this table: Component NaCl MnSO4.H₂O H3BO3 CaSO4.5H2O NazMo04.2H₂O COSO4.7H2O KI CaCl2.2H₂O NiCl2 ZnSO4.7H2O FeSO4(NH4)2. 6H20 1X concentration 0.06 g/L 0.024 g/L 0.5 mg/L 0.5 mg/L 2 mg/L 0.0023 mg/L 0.1 mg/L 0.2 g/L 0.0025 mg/L 12 mg/L 35 mg/L 20X (Provide unit)Food is often irradiated with either x rays or electron beams to help prevent spoilage. A low dose of 5–75 kilorads (krad) helps to reduce and kill inactive parasites, a medium dose of 100– 400 krad kills microorganisms and pathogens such as salmonella, and a high dose of 2300–5700 krad sterilizes food so that it can be stored without refrigeration. (a) A dose of 175 krad kills spoilage microorganisms in fish. If x rays are used, what would be the dose in Gy, Sv, and rem, and how much energy would a 220 g portion of fish absorb? (See Table 43.3.) (b) Repeat part (a) if electrons of RBE 1.50 are used instead of x rays.
