On which of the following factors does the amount of energy absorbed by an endothermic reaction depend? O Number of reactants
O Physical state of the reactant
O Sum of the potential energy of the reactants and products
O Difference in the potential energy of the reactants and products

D!! ( difference in the potential energy of the reactants and products )

Explanation:

i have the same test

explanation:

i think option no d is the correct answer

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
