A100.0 ml sample of 0.200 m hcl is mixed with a 100.0 ml sample of 0.205 m naoh in a coffee cup calorimeter. if both solutions were initially at 25.0 c and the temperature of the resulting solution was recorded as 27.0 c, determine the delta hrxn (in kj/mol). assume no heat is lost to the calorimeter. hint: what is the limiting reagent?

Balance this equation: n2 + h2 > nh3, write the following molar ratios: n2 / n2 / nh3 h2 /
