The answer is A. The “plums” or the “raisins” of the pudding are the electrons. The actual “pudding” is the nucleus, which is made up of protons and neutrons, so it is a large positively charged mass.

False. A physical change does not create a new substance.
That answer is either 3 or 4, but I truly forgot which of the two.
Answer:
a. 0.66 atm
Explanation:
Pi = 750 torr = 0.99 atm. Pf = ?
Vi = 400 ml Vf = 600ml
Using PiVi = PfVf
Then 400ml × 0.99atm = Pfatm × 600ml
Solving for Pf, we have,
Pf = (400ml × 0.99atm)/600ml
Pf = 0.66atm
