6. Please answer and show all work, thank you!!:) **Combustion and Internal Energy Change:****Problem Statement:**The combustion of 0.250 grams of ethane gas, \( \text{C}_2\text{H}_6 \), causes a temperature rise of 2.50°C in a bomb calorimeter that has a heat capacity of 300 J/°C. What is the internal energy change in kJ/mole for this reaction?**Explanation:**In this scenario, the rise in temperature is measured using a bomb calorimeter, a device used to determine the heat of combustion of a substance. The heat capacity of the calorimeter indicates the amount of heat required to raise the temperature by 1°C. The internal energy change is calculated from the temperature change and the heat capacity of the calorimeter. The energy change can then be converted into kJ/mole for better understanding in a chemical reaction context.

Given: The mass of ethane combusted = 0.250 g The rise in temperature = 2.50 oC The heat capacity of…

please can you please do questions 7, 8 and 9 please I would really appreciate it if you can do all I would appreciate if you could do all please answer super super super fast I really need it its really important answer fast this is not a graded question
In our first lab experiment we will be identifying metals by measuring theirdensities and comparing them to known values. Here at NJIT we have a very large and generouslaboratory materials budget, so all sorts of exotic and extremely valuable metals will be providedfor the experiment. Using the values listed below, determine the identity of the metal samples.If the density value determined is not amongst the values below then one of those cheapRutgers samples crept into our stock of metal samples and you should answer “unknown metal”.Note: volume measurements are not very exact. If your density determination is off by 0.1 or0.2 from the known value, that’s probably good enough for an identity. Table in image 4a. You weigh your sample and determine it weighs 71.8 grams. You put the sample into 15.6 mL ofwater and the total volume rises to 22.4 ml. What metal do you have?4b. You weigh your sample and determine it weighs 56.3 grams. You put the sample into 28.9 mL ofwater and the total…
