Anna was asked to identify and explain if the equation CO2 (g) → CO2 (I) 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 endothermic reaction because the energy is released from gaseous CO2 to the surroundings to become liquidCO, causing the molecules to speed up.

hello, i need help with this question It is quite common for a solid to change from one solid state structure to another at a temperature below its melting point.For example, sulfur undergoes a phase change from the α-orthorhombic form (S8; density≅2.07 g/cm3) to the β-monoclinic form (S8; density≅2.00 g/cm3) as it is warmed above 95.3 °C.Assuming that ΔH for this phase change is 0.220 kJ/mol, calculate ΔS for this phase change.
Isooctane (2,2,4-trimethylpentane), one of the many hydrocarbons that make up gasoline, burns in air to give water and carbon dioxide. 2 C3H13 (2) + 25 02 (g) → 16 CO2(g) + 18 H2O(£) A,H° = -10,922 kJ/mol-rxn What is the enthalpy change if you burn 7.50 L of isooctane (d = 0.69 g/mL)?

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.
