Microwave light has a wavelength of 1.0 x 10-2 m. Calculate the number of photons required to heat 82.0g of water from 25.3 °C to 34.1 °C? (Speed of light = 3.0 x108 m/s)
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 23 kg of sucrose (C12H22 O11) per hour per hectare (1 ha = 10,000 m²). Assuming
that sucrose is produced by the reaction
12CO₂(g) + 11H₂O(l) → C12H22 O11 (8) + 1202 (9) AH = 5640 kJ
calculate the percentage of sunlight used to produce the sucrose - that is, determine the efficiency of photosynthesis in this field.

Anna was asked to identify and explain if the equation CO2 (l) → CO2 (g) was an endothermic or exothermic reaction. However she got it wrong. What is her error and what should the answer have been?
Anna's statement: The equation is an exothermic reaction because the energy is released from liquid CO2 to the surroundings to become gaseous CO2 causing the molecules to slow down.
