<span>is a measure of the average kinetic energy of a group of molecules I think its true</span>
Answer:
P= 138.6 atm or 1.4x10²
Explanation:
You will need to use PV=nRT to solve for P, pressure
Where the R constant is 0.08206 L atm mol^-1 K^-1
V is 1.2 L
T is temperature in kelvin, 273.15+25= 298.15
n is 6.8 mol
P*1.2=6.8*0.08206*298.15 ---> P*1.2=166.3700852 ---> P=166.3700852/1.2
P=138.6 atm
or 1.4x10²
Answer:
double replacement (Mutual exchange of ions)
