13 Natural gas, or methane, is an important fuel. Combustion of one mole of methane releases 802.3 kilojoules of energy. How much energy does that represent in kilocalories? Group of answer choices 1.92 × 10–1 kcal 1.92 × 102 kcal 3.36 × 103 kcal 1.92 × 105 kcal 3.36 × 106 kcal
Food contains three main categories of compounds: carbohydrate, protein, and fat. Arctic explorers often eat a high-fat diet because fats have a high food value. The average food values for carbohydrate, protein, and fat are 4 Cal/g, 4 Cal/g, and 9 Cal/g, respectively. Consider a typical fat to have the chemical formula C18H36O2, glucose (C6H12O6) to be a representative carbohydrate, and the amino acid alanine (C3H6NO2) a building block of proteins. Express the food values given above in kJ/mol.
