Two pollutants that form in auto exhaust are CO and NO. An environmental chemist must convert these pollutants to less harmful gases through the following: CO(g) + NO(g) → CO₂(g) + N2(g) AH = ? Given the following information, calculate the unknown AH: Equation A: Equation B: CO)+}02(g) → CO2(g) NO(g) → N₂(g) + O2(0) AH = - 283.0 kJ - AH-90.3 kJ

The decomposition reaction of sodium bicarbonate or baking soda is an important chemical reaction for baking because it helps baked goods rise. It's also how you can make sodium carbonate, another useful chemical, also called washing soda. The balanced equation for the decomposition of sodium bicarbonate into sodium carbonate, carbon dioxide, and water is: 2 NaHCO3(s) → Na2CO3(s) + CO2(g) + H2O(g) When 29.27 grams of NaHCO3 decomposes what is the volume of CO2 formed at stp?

A chemical reaction takes place inside a flask submerged in a water bath. The water bath contains  2.70kg  of water at  39.2°C . During the reaction  128.kJ  of heat flows out of the bath and into the flask. Calculate the new temperature of the water bath. You can assume the specific heat capacity of water under these conditions is  4.18·J·g−1K−1 . Be sure your answer has the correct number of significant digits.

When 145 mL of 0.212 M NaCl(aq) and 145 mL of 0.212 M AgNO3(aq), both at 21.1°C, are mixed in a coffee cup calorimeter, the temperature of the mixture increases to 23.7°C as solid AgCl forms. NaCl(aq) + AgNO3(aq) → AgCl(s) + NaNO3(aq) This precipitation reaction produces 3.14 ✕ 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.

The reaction shown below represents the formation reaction of water. 2 H2 (g)   +   O2 (g)   →   2 H2O (g)
