What type of anxiety describes a “checker”?

@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 16.11 g of kaolinite?

@X@user.full_name@X@ @GMU: What is the free energy change at 25°C for the reaction below, if ΔGfo(CH4(g) = -50.790 kJ/mol, ΔGfo(C2H2(g)) is 209.214 kJ/mol.C2H2(g) + 3H2(g) → 2CH4(g)

@X@user.full_name@X@ @GMU: What is the wavelength of photons having an energy of 0.00480 kJ/mol. Remember Planck’s constant is 6.626×10-34 J×s

@X@user.full_name@X@ @GMU: What is the balanced reaction for the following galvanic cell?Al(s)| Al3+(aq) || Fe3+(aq) | Fe(s)

@X@user.full_name@X@ @GMU: Closed-tube manometers work exactly as barometers except by connecting them to a container its pressure can be measured. Assume you have a closed-ended manometer filled with an oil having a density of 0.7763 g/mL at 20°C rather than mercury (density = 13.546 g/mL at 20°C). What is the pressure if the height of the oil column is 1135.17 cm?

Sadie is so fearful of being overwhelmed by anxiety that she rarely steps outside her apartment. The thought of going shopping and getting lost in a crowd terrifies her, so she has her groceries delivered. Because of her fear, she earns her living as a freelance writer, working at home. Sadie’s behavior is most characteristic of

@X@user.full_name@X@ @GMU: What is the free energy change at 25°C for the reaction below, if ΔGfo(CH4(g) = -50.790 kJ/mol, ΔGfo(C8H18(g)) is 17.379 kJ/mol.C8H18(g) + 7H2(g) → 8CH4(g)
