Using oxidation number to support your answer , state which reactant is acting as an oxidising agent and which is acting as a reducing agent . CH4(g)+4CuO(s)》4CU(s)+CO2(g) +H2O(g)

i think 4.44 moles

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 is the correct answer

mark me brainliest and hope this

b.

the accuracy of the data.
