If 35.0 kJ of thermal energy is added to a 2.50 kg sample of copper, the temperature change is calculated to be °C Record your 3-digit answer; do not include units Use the following information to answer the next question. Splenda™ is a mixture of dextrose, added for flavour, maltodextrin, to add volume, and sucralose, added to increase sweetness. A sample of dextrose is burned in a calorimeter that contains 250.0 g of water. The temperature of the water increases by 4.56°C. Given this information, the thermal energy absorbed by the water is calculated to be kJ. (Use 4.19 Joules per gram per degree C as the specific heat capacity for water). Record your 3-digit answer; do not include sign or units. Use the following information to answer the next question. The following reaction equation represents the complete combustion of ethanediol. 2C₂H4(OH)2(1) + 50₂(g) → 4CO₂(g) + 6H₂O(g) AcHo-2359 kJ The mass of ethanediol that must be burned to raise the temperature of 250.0 g of water from 20°C to 35°C is 9. Record your answer to 2 decimal places; do not include units
