In this experiment, you obtain a percent recovery for carbon dioxide in Part A, which you then use in Part B with the antacid. Why can you use the same percent recovery for both parts? (Select all that apply)

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

b) nuclear ive learned that in a pedtrodic table
