I don't know what you were trying to copy or type in Choice-E .
All three statements are true, so the answer should say "I, II, and III".
Answer:
28.295244 MeV
Explanation:
= Mass of proton = 1.007276 u
= Mass of neutron = 1.008665 u
= Mass of electron = 0.000549 u
Mass of reactant is 4.002604 u
Mass of the products is
(2 because there are 2 of each)
The difference in mass is
So, the work done in MeV would be
The work done required to completely disassemble all the helium is 28.295244 MeV
The lack of a subscript after the 0 means that there is only one oxygen (0).
There are 2 hydrogen molecules and 1 oxygen molecules
hope this helps
As the volume of the container increases the pressure inside will decrease because the atoms have more room to move around in.
No scientific testing has been made to check for ion transfer, and the claims are purely empirical. Also, nine out of ten people is hardly a representative sample, and the people can claim whatever they want since "feeling" is subjective. This is most likely a pseudoscientific claim, made to sound legitimate to consumers. The best answer is choice D.
