Answer:
7.01 mol CH4
Explanation:
STP means standard temperature and pressure, so they are basically telling you that the gas is at 1 atm and 273 K (0 degrees celsius). Now that we have the pressure, volume, and temperature we can use the ideal gas law and solve for n or moles
PV=nRT
n=PV/RT
n=(1)(157)/(0.08206)(273)
n=7.0081 (round to 3 sigfigs)
n=7.01 mol
The answer is TRUE.
If the Energy is on the left, then the problem is true. If it is on the right then it would be negative, false, and considered as exothermic.
Endothermic reaction = the products are higher in energy than the reactants.
Exothermic reaction = a chemical reaction that releases energy by light or heat.
Answer:
Temperature, pressure, shape of container
