writing the solubility constant expression, and solving for molar solubility. The value of Ksp for BaCOs is 5.0 x 109. Complete Parts 1-3 before submitting your answer. PREV 1 3 NEXT > Using the values from the ICE table (Part 1), construct the expression for the solubility constant, Ksp. Each reaction participant must be represented by one tile. Do not combine terms. Ksp = [x] [1.4 x 10] = 5.0 × 10-9

The sun supplies energy at a rate of about 1.0 kilowatt per square meter of surface area (1 watt =1 J/s). The plants in an agricultural field produce the equivalent of 13 kg of sucrose (C12 H22 O11) per hour per hectare (1 ha : 10,000 m²). Assuming that sucrose is produced by the reaction 12CO2 (g) + 11H2O(1) → C12 H22 O11 (s) + 1202 (g) AH=5640 kJ calculate the percentage of sunlight used to produce the sucrose that is, determine the efficiency of photosynthesis in this field. Percent efficiency %
