(a)
Interpretation:
The standard state of the compound
Concept Introduction:
The standard state of an element or a compound is defined as the stable phase of the element or compound exists at standard conditions that is
Example:
Standard state of element Fluorine is gaseous state because it exists in gaseous phase at

General Chemistry
- Graphite is burned in oxygen to give carbon monoxide and carbon dioxide. If the product mixture is 33% CO and 67% CO2 by mass, what is the heat from the combustion of 1.00 g of graphite?arrow_forwardCombustion of table sugar produces CO2(g) and H2O( l). When 1.46 g table sugar is combusted in a constant-volume (bomb) calorimeter, 24.00 kJ of heat is liberated. a. Assuming that table sugar is pure sucrose, C12H22O11 (s), write the balanced equation for the combustion reaction. b. Calculate E in kJ/mol C12H22O11 for the combustion reaction of sucrose.arrow_forward9.31 A metal radiator is made from 26.0 kg of iron. The specific heat of iron is 0.449Jg1C1 . How much heat must be supplied to the radiator to raise its temperature from 25.0 to 5 5.0°C?arrow_forward
- How much heat is absorbed by a 44.7-g piece of leadwhen its temperature increases by 65.4°C?arrow_forwardA piece of lead of mass 121.6 g was heated by an electrical coil. From the resistance of the coil, the current, and the Time the current flowed, it was calculated that 235 J of heat was added to the lead. The temperature of the lead rose from 20.4C to 35.5C. What is the specific heat of the lead?arrow_forwardHow much heat is released when a mixture containing 10.0 g NH3 and 20.0 g O2 reacts by the following equation? 4NH3(g)+5O2(g)4NO(g)+6H2O(g);H=906kJarrow_forward
- Describe a simple calorimeter. What measurements are needed to determine the heat of reaction?arrow_forwardThe white pigment TiO2 is prepared by the reaction of titanium tetrachioride, TiCl4, with water vapor in the gas phase: TiCl4(g)+2H2O(g)TiO2(s)+4HCl(g). How much heat is evolved in the production of exactly 1 mole of TiO2(s) under standard state conditions?arrow_forward9.32 The material typically used to heat metal radiators is water. If a boiler generates water at 79.5°C, what mass of water was needed to provide the heat required in the previous problem? Water has a specific heat of 4.184Jg1 C1 .arrow_forward
- Consider the following reaction in a vessel with a movable piston. R(g)+T(g)X(g)As the reaction takes place, the piston loses 1072 J of heat. The piston moves down and the surroundings do 549 J of work on the system. What is E?arrow_forwardHow much heat is released when a mixture containing 10.0 g CS2 and 10.0 g Cl2 reacts by the following equation? CS2(g)+3Cl2(g)S2Cl2(g)+CCl4(g);H=230kJarrow_forwardGiven 2Al2O3(s)4Al(s)+3O2(g)H=3351.4kJ (a) What is the heat of formation of aluminum oxide? (b) What is H for the formation of 12.50 g of aluminum oxide?arrow_forward
