find the dH when 56g of AgNO3 (M = 169.9 g/mol) reacts. If the heat involved (derived from answer a) is transferred without loss to 100.0g of water at 25ºC. what is the final temperature of the water (CH2O = 4.18J/gºC)?

What is the AH°rxn for the reaction of gaseous ammonia and oxygen gas to form gaseous nitrogen monoxide and water vapor? Use the given standard heats of formation. Write the balanced chemical reaction. AH°; NH3 (g) AH°;02 (g) = 0 AH°;NO (g) = 103.56 kJ/mol AH°; H20 (g) = -218.42 kJ/mol = -38.17 kJ/mol %3D

A student runs two experiments with a constant-volume "bomb" calorimeter containing  1300.g  of water (see sketch at right). First, a  6.000g  tablet of benzoic acid  C6H5CO2H  is put into the "bomb" and burned completely in an excess of oxygen. (Benzoic acid is known to have a heat of combustion of  /26.454kJg .) The temperature of the water is observed to rise from  14.00°C  to  39.98°C  over a time of  14.9  minutes. Next,  5.570g  of acetylene  C2H2  are put into the "bomb" and similarly completely burned in an excess of oxygen. This time the temperature of the water rises from  14.00°C  to  60.18°C . Use this information, and any other information you need from the ALEKS Data resource, to answer the questions below about this reaction:   A "bomb" calorimeter. →+2C2H2g  5O2g + 4CO2g  2H2Og Be sure any of your answers that are calculated from measured data are rounded to the correct number of significant digits.
