The choices with ** are the ones I think is the right answer, but then I always doubt myself. so please help. thank you in advance to all!
7. What is the MOST massive particle?
A. Alpha particle **
B. electron
C. proton
D. neutron
18. How does a nuclear reaction differ from a chemical reaction?
A. In a chemical reaction elements are created and destroyed
while all elements are conserved in a nuclear reaction.
B. There is no actual difference in the two reactions. The only
difference is that a nuclear reaction emits radiation while a
chemical reaction emits heat. **
C. Entropy is increased in a chemical reaction while it is
decreased in a nuclear reaction.
D. In a nuclear reaction the elements change identities; in an
ordinary chemical reaction they do not.
E. Entropy is increased in a nuclear reaction while entropy
decreases in a chemical reaction.
[:CHEMISTRY QUESTION !!?
well it seems that you have it correct. great jobCHEMISTRY QUESTION !!?

Yes! An alpha particle is fancy for an atom of helium with a mass of 4.

Never destroyed nor created!!!!

Sounds legit!!
C. Entropy is increased in a chemical reaction while it is
decreased in a nuclear reaction.
Spontaneity generally always increases ... espec. in these reactions!!!
D. In a nuclear reaction the elements change identities; in an
ordinary chemical reaction they do not.
Nope ... identities change equally.
E. Entropy is increased in a nuclear reaction while entropy
decreases in a chemical reaction.
Nopers ..
Great Job! It checks out with me. =D
