Answer:
A) 122 atm
Explanation:
PV = nRT
Solve for P --> P = nRT/V
n = 10.0 mol + 5.0 mol = 15.0 mol
R = 0.08206 L atm / mol K
T = 25 + 273 = 298 K
V = 3.0
P = (15.0)(0.08206)(298) / (3.0) = 122 atm
153g/mols I think this is the answer but not 100% sure.
NaCI this wht forms when sodium and choride combine
Explanation:
Work done = force * perpendicular distance
= 1 * 0.01 = 0.01 joules
