PV = nRT
P is pressure, V is volume in L, n is number of moles, R is the gas constant, and T is temperature in K
(1.23 atm)(10.3 L) = (n)(.08206)(29.8 + 273)
n = .5 moles x 38 grams per mol F2 = 19.4 grams F2
Answer:
nitrate and sodium are spectator ions .The reactions that form an aqueous solution are often a spectator ions.
I believe the answer is D because warm water generally has more nutrients than cold water.
It does not improve the nutrients so it isn't B or C.
Hope this helps!
I. The solubility of NaCl at 25 degrees C would be between the solubilities at 20 and 30 degrees C. A reasonable answer would be 36 grams/100 g water
ii. From the table, it’s clear that the salts are more soluble at higher temperatures, indicating that an increase in temperature increases solubility.
iii. At 50 degrees C, a saturated ammonium chloride solution will have 50.6 grams of salt per 100 g water. At 20 degrees C, the solution can hold only 37.3 grams of salt per 100 g water. Thus, 13.3 grams of salt will precipitate per 100 grams of water.
