Explanation:
I) carbon dioxide
ii) nitrogen dioxide
iii) nitric acid

<span>A generator converts mechanical energy into
electrical energy, while a motor does the opposite - it converts
electrical energy into mechanical energy.</span>
Reduction <span>always results in a lowering of the oxidation number. The reaction of the system above is written as:
</span><span>Cu2+(aq) + Fe(s) --> Cu(s) + Fe2+(aq)
</span>
From the reaction, we see that copper goes from the +2 to a neutral charge. Lowering of the oxidation number happens so this is the element that is being reduced.
Answer: they both have the same molecular formula but different structural formulae
Explanation:
hope this helps :)
Answer:
c
Explanation:
b and d are out, the variables are changed. a would be a repetition, not a replication. c uses the same method and variables with a different control group
