Answer:
The over all reaction :
The standard cell potential of the reaction is 0,.897 Volts.
Explanation:
Reduction at cathode :
..[1]
Reduction potential of 
to 
Oxidation at anode:
.[2]
Reduction potential of 
to 
To calculate the 
of the reaction, we use the equation:
Putting values in above equation, we get:
The over all reaction : 2 × [1] + [2]
The standard cell potential of the reaction is 0,.897 Volts.
Answer:
1. electrons
2. From "Y" to "X"
Explanation:
1. Electrons move between the rod since the electrons are the only charge carriers which are free to move.
2. The particles move from from "Y" to "X" since the electrons are the only charge carriers which are free to move. The positive charge on rod x is due to a deficit of electrons while the negative charge on rod Y is due to the excess of electrons. When the rods come together, the electrons move from "Y" to "X" since the electrons are the only charge carriers which are free to move.
The correct answer is option d, that is, atoms of the element.
As the atoms are neither destroyed nor created in a chemical reaction, the sum of the mass of the products in a reaction must be equivalent to the sum of the mass of the reactants.
The chemical reactions must be balanced, they must exhibit a similar number of atoms of each element on both the sides of the equation. As a consequence, the mass of the reactants must be equivalent to the mass of the products of the reaction.
I believe that the answer is A) All Nitrogen atoms have 7 protons
