- Chaeyoung wants to study the heat transfer between a 50 g of heated block of iron (cFe = 0.449 J/g ⁰C) at 500 ⁰C and 100 g of water (cH2O = 4.184 J/g ⁰C) at 10 ⁰C using a calorimeter. Find qH2O and qFe.Carla and her friends were tasked with determining the heat of reaction for the neutralization of the newly synthesized monoprotic acid HX and NaOH. The rubber ball calorimeter was initially calibrated using the reaction of 7.0 mL of 0.200 M HCl and 14.0 mL of 0.1000 M KOH. This measured a temperature rise from 15.7 °C to 27.9 °C. After that, the heat of reaction was calculated for a combination of 2.00 mL of 1.00 M NaOH and 5.0 mL of 1.00 M HX. This represented a temperature rise of 3.7 degrees Celsius. What is the calorimeter's heat capacity in J/°C? (Δ??????????????? =-55.85 kJ/mol)? For the reaction between NaOH and HX, create the chemical and net ionic equations that are equally balanced.In a coffee press, you combine solid coffee grounds and hot water. After a long time, the ground coffee beans are still visible, and the water has turned into a rich dark brown (some of the coffee has dissolved into the liquid). You push the filter in the press down and pour out only the dark water into a cup. You then add milk and sugar to the cup. You also notice that the filter must have a hole in it because there are coffee grounds also in your cup. Calculate the degree of freedom in this system (your cup) at equilibrium. 1 2 3 4
