Pls me answer this brainliest to the correct person and a yo (also 5 stars.)

I believe that C is correct. If you look at the moles for both the product and reactant (the coefficients in front of the compounds) the reactant has one mole (a coefficient of one) and the product has two moles (a coefficient of two). This means that one unit of the first gas/ the reactant decomposes into two units of the second gas/the product. This is all because a mole is the amount of a substance.

Hope this helped!

Option B. Is the correct answer you're looking for.

quartz

explanation:

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
