Which of the following is characteristic of a nuclear reaction?

i. electrons in atomic orbitals are involved in the breaking and forming of bonds

ii. elements are converted from one to another

iii. reaction rates are typically not affected by catalysts

iv. atoms are rearranged by the breaking and forming of chemical bonds

a. i and ii

b. i, ii, and iii

c. ill and iv

d. ii and iii

e. i, ii, iii and iv

d

Explanation:

Nuclear reactions unlike chemical reactions do not involve electrons or bonds.The main use for the reaction is neutrons. In nuclear there is only turning the element into another element and releasing a large amount of  energy. So catalyst are also redundant in nuclear reactions.  

Therefore, points III and 3 are true, and rest are all wrong. therefore option d is correct

graph slopes whilst gas cools, then it is flat whilst conensation to liquid happens, the coolong liquid then graphs as a slope when it solidifies graph is flat

latent heat

lol
