Apr 29, 2024 · Derive reaction quotients from chemical equations representing homogeneous and heterogeneous reactions. Calculate values of reaction quotients and equilibrium constants, using concentrations and pressures. Relate the magnitude of an equilibrium constant to properties of the chemical system.
6 days ago · A very good ratio would be 3.5:1 or lower. The normal amounts of HDL are between 35 and 65 milligrams per deciliter (mg/dL) in adult males, and 35 to 80 mg/dL in females. When your overall cholesterol is over 200 mg/dL, you may be at higher risk of heart disease. If your chol/HDL level is high, your healthcare provider may want to discuss ...
5 days ago · 0.36 g of Mg combines with chlorine to produce 1.425 g of magnesium chloride. 9.50 g of. another sample of anhydrous magnesium chloride gave, on electrolysis, 2.24 litre of chlorine at NTP. Show that these data agree with the law of constant proportions.
4 days ago · The solubility of oxygen in water is temperature-dependent, and about twice as much (14.6 mg/L) dissolves at 0 °C than at 20 °C (7.6 mg/L). [11] [48] At 25 °C and 1 standard atmosphere (101.3 kPa ) of air, freshwater can dissolve about 6.04 milliliters (mL) of oxygen per liter , and seawater contains about 4.95 mL per liter. [49]

10 hours ago · Methane is a tetrahedral molecule with four equivalent C–H bonds. Its electronic structure is described by four bonding molecular orbitals (MOs) resulting from the overlap of the valence orbitals on C and H. The lowest-energy MO is the result of the overlap of the 2s orbital on carbon with the in-phase combination of the 1s orbitals on the ...

6 days ago · The food enzyme has a temperature optimum around 49°C (pH 7.0) and a pH optimum around pH 7.0 (30 C). 18 Thermostability was tested after a pre-incubation of the food enzyme for 15 min at different temperatures (pH 7.0). The sucrose phosphorylase activity decreased sharply above 65°C, showing no residual activity after pre-incubation at 70°C. 19
