Explanation:
Answer:
endothermic
Explanation:
Heat is added to make the process possible.
Answer:
The pressure is 16, 9 atm
Explanation:
We use the formula PV=nRT. The temperature in Kelvis is: 273 + 25 = 298K
PV=nRT P =(nRT)/V
P= (0, 450 mol x 0,082 l atm/K mol x 298)/0,650 l= 16, 91723077atm
This is the answer its very useful and very helpful
