The first law of thermodynamics states the conservation of energy and heat where the <span>total energy in an isolated system may be transformed into another, but never created or destroyed. If 314 J of energy was released to the room, then also 314 J of energy was also removed from food in that refrigerator assuming it is an isolated system. </span>
Answer: 20 mol CH4 x 1CO2 / 1CH4 = 20mol CO2
Answer: 20mol CO2
Explanation:
Answer:
Change in temperature of calorimeter is 
Explanation:
Molar mass of anethole = 148.2 g/mol
So, 0.950 g of anethole = 
of anethole = 0.00641 moles of anethole
1 mol of anethole releases 5541 kJ of heat upon combustion
So, 0.00641 moles of anethole release 
of heat or 35.52 kJ of heat
7.854 kJ of heat increases 
temperature of calorimeter.
So, 35.52 kJ of heat increases 
or temperature of calorimeter
So, change in temperature of calorimeter is
Decreasing the volume increases the pressure, therefore due to Le Chatelier's principle, we can see that more HI2 will be formed as 2 molecules combine into 1 and that conserves space which in turn lowers the pressure.
