The molar heat of fusion for water is 6.020 kilojoules/mole. How much energy required to melt 81.00 grams of H20 A)208.4 kJ
B)18.00 kJ
C)27.09 kJ
D) 15.56 kJ

h let me think

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current

i would say b

explanation:

but i think i would need more information than that

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.
