Some power plants produce electricity from burning coal .The energy released from burning the coal is used to turn water in to steam. The steam spins turbines of large generators that produce electricity. Which of the following best shows the sequence of energy transformations described above? A. thermal to mechanical to chemical to electrical
B. chemical to thermal to mechanical to electrical
C. electrical to chemical to mechanical to thermal
D. mechanical to chemical to thermal to electrical

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6

explanation:

2b2t

you did not give any options thus this is the best answer i can give to you with this little information you have given

> they are both natural and not man made

> they can be tracked and predicted by the right tools
