Using Hess's Law to calculate net reaction enthalpy Nitric oxide (NO) can be formed from nitrogen, hydrogen and oxygen in two steps. In the first step, nitrogen and hydrogen react to form ammonia: N₂(g) + 3H₂(g) → 2NH3(g) In the second step, ammonia and oxygen react to form nitric oxide and water: 4 NH3(g) + 50₂(g) → 4NO(g) + 6H₂O(g) ΔΗ= - 905. kJ ΔΗ= - 92. kJ Calculate the net change in enthalpy for the formation of one mole of nitric oxide from nitrogen, hydrogen and oxygen from these reactions.

2. A small immersion heater was used to heat water in an insulated cup. The heater was placed in 100.0 g of distilled water initially at 21.0°C, and turned on for 60.0 seconds while the water was stirred with a thermometer. The final temperature of the water was measured to be 37.5°C. Assume the specific heat capacity of the water is 4.18 J/g °C. (a) Calculate the total heat energy in joules absorbed by the water and the average power in watts (1 watt = 1 joule/s) delivered by the heater. The heater was used to deliver 3000 joules of energy to 100.0 g of methanol (CH,OH(E)) in the same manner. The temperature of the methanol increased by 11.8 Celsius degrees. (b) Calculate the specific heat capacity of the methanol liquid. (c) (i) Calculate the mass of water (H,O, Co= 4.181 Jgl °C-) at 20.0°C that would be requireć %3D to cool a 30.0-g block of copper (Cu, co0.385 J gl °C-l) from 50.0°C to 25.0°C in an insulated cup. %3D (ii) Which liquid, water or methanol, would be more effective as…
A chemist carefully measures the amount of heat needed to raise the temperature of a 1.27kg sample of C4H6O2 from 41.3°C to 60.6°C. The experiment shows that 3.87 × 10^4J of heat are needed. What can the chemist report for the molar heat capacity of C4H6O2? Round your answer to 3 significant digits. = J⋅mol−1K−1
When 130. mL of 0.198 M NaCl(aq) and 130. mL of 0.198 M AgNO3(aq), both at 21.8°C, are mixed in a coffee cup calorimeter, the temperature of the mixture increases to 24.2°C as solid AgCl forms. NaCl(aq) + AgNO3(aq) → AgCl(s) + NaNO3(aq) This precipitation reaction produces 2.60 ✕ 103 J of heat, assuming no heat is absorbed by the calorimeter, no heat is exchanged between the calorimeter and its surroundings, and that the specific heat and density of the solutions are the same as those for water (4.18 J/g·°C, and 0.997 g/mL, respectively). Using this data, calculate ΔH in kJ/mol of AgNO3(aq) for the given reaction. This is the complete question, nothing was left out. Thank you
