3NO2(g)+H2O(02HNO3(aq)+NO(g)H=??? Use the following data in your calculation 2NO(g)+O2(g)2NO2(g)2N2(g)+5O2(g)+2H2O(l)4HNO3(aq))N2(g)+O2(g)2NO(g)H=116kJ/molH=256kJ/molH=+183kJ/mol A) 119KJ/mol B) 394KJ/mol C) 137KJ/mol D) 189KJ/mol Q2- When 50.0g of 0.200MNaCl(aq) is added to 100.0g of 0.100MAgNO3(aq) at 24.1C in a calorimeter, the temperature change to 25.2C as AgCl(s) forms. Assuming the specific heat of the solution and products is 4.20J/gC, calculate the approximate amount of heat of the solution in joules. A) 693J B) 462J C) 693J D) 462J
