@X@user.full_name@X@ @GMU: A flexible container was filled with N2 gas at a pressure of 1.027 atm and volume of 16.325 L. What volume would this same gas occupy if the pressure increased to 1.751 atm? Assume temperature is constant.

If you are diagnosed with a mental health issue, labels matter.

@X@user.full_name@X@ @GMU: What is the standard cell voltage at 25.0oC for the reverse of the reaction below?2MnO4-(aq) + Cu(s) → 2MnO42-(aq) + Cu2+(aq) K = 2.76e7

@X@user.full_name@X@ @GMU: Kaolinite, a clay mineral with the formula Al4Si4O10(OH)8, is produced naturally by the chemical weathering of aluminum silicate minerals like feldspar (granite). Kaolinite is used industrially as filler in slick-paper for magazines and as a raw material for ceramics. How many grams of oxygen are present in 15.99 g of kaolinite?

@X@user.full_name@X@ @GMU: Assume you have an open ended manometer filled with an oil having a density of 0.7363 g/mL at 20°C rather than mercury (density = 13.546 g/mL at 20°C). What is the pressure in atmospheres if the level of the arm open to the atmosphere is 142.30 cm lower than the level in the arm connected to the gas sample? The atmospheric pressure reading is 759.42 mm Hg.
