Answer:
Cu
Explanation:
We can use oxidation numbers to figure out what is happening with the electrons.
The oxidation number of Cu increases from 0 to +2 in Cu(NO₃)₂. The copper has gained two positive charges, so it has lost two electrons. It has been oxidized, so it is the reducing agent.
NO₃⁻ is wrong. The oxidation number of N decreases from +5 in NO₃⁻ to +4 in NO₂, so it has been reduced. It is the oxidizing agent.
Cu(NO₃)₂ and NO₂ are wrong. They are the products of the reaction. They cannot be either oxidizing or reducing agents in this reaction
The answer is a Roman numeral.
Ex:
1: I
2: II
3: III
4: IV
5: V
6: VI
7: VII
8: VIII
9: IX
10: X

Answer:
Autotrophic or Producers
Explanation:
They are often called producers because they make their own food.
The question is incomplete. The complete question is :
Hydrogen 
gas and oxygen 
gas react to form water vapor 
. Suppose you have 11.0 mol of 
and 13.0 mol of 
in a reactor. Calculate the largest amount of 
that could be produced. Round your answer to the nearest 0.1 mol .
Solution :
The balanced reaction for reaction is :
11.0 13.0
11/2 13/1 (dividing by the co-efficient)
6.5 mol 13 mol (minimum is limiting reagent as it is completely consumed during the reaction)
Therefore, is limiting reagent. It's stoichiometry decides the product formation amount from equation above it is clear that number of moles for will be produced = number of moles of
= 11.0 mol
