Which statement about Delta. Hf is true? It is zero for any compound in its standard state. It is positive when the bonds of the product store more energy than those of the reactants. It is negative when a compound forms from elements in their standard states. It is zero for any element that is in the liquid state.

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

there are no statements provided but here is why:

sulfur belongs to group 16 because it can be found in nature whether it is in a free or combined state.

hope this
