A researcher studying the nutritional value of a new candy places a 3.60 g sample of the candy inside a bomb calorimeter and combusts it in excess oxygen. The observed temperature increase is 2.02 °C. If the heat capacity of the calorimeter is
31.10 kJ. K-, how many nutritional Calories are there per gram of the candy?

the equation that correctly represent the reaction for formation of ammonia is

n2+ 3h2 → 2nh3 (answer d)

1 mole of nitrogen gas (n2) react with 3 moles of hydrogen gas (h2) to form 2 moles of ammonia ( nh3). this is in a process known as haber process were iron is used as a catalyst and reaction take place that a higher temperature and pressure. the process is exothermic hence energy is released.

the answer is true.

the answer is b. dilution
