Solve the following problems:
Problem I: Calculate the low calorific power of methane CH4 with air at 298 K, assuming that the products of reaction are CO2 and H2O(gas).
Problem II: Determine the heat of reaction of ethane C2H6 in cal/mol and kcal/m3.
Problem III: Determine the low calorific power of natural gas analyzing 83% CH4, 16% C2H6, and 1% N2.
Show how you get the answer, so that I can better understand how to do it.
A plastic ball in a liquid is acted upon by its weight and by a buoyant force. The weight of the ball is 4.8N. The buoyant force has a magnitude of 6.5N and acts vertically upward. External force acting on the ball maintains it in the state of res..
