Given the reaction: 4NH3 + 502 4NO + 6H2O
Ainat [17]

Answer:

\frac{4}{5} moles

Explanation:

The reaction equation is given as:

      4NH₃   +  5O₂  →  4NO  +  6H₂O

The number of moles of O₂ that completely reacted is given as 1 mole

To solve this problem, we are going to use a stoichiometric approach from the balanced reaction equation:

         5 moles of O₂ will react completely to produce 4 moles of NO

        1 mole of O₂ will therefore react to produce  x mole of NO

               5x  = 4

                 x  = \frac{4}{5} moles of NO

I would see chemical constitution and physical components are not changed. 

Because physical reaction won't change the component itself

Two voltaic cells are to be joined so that one will run the other as an electrolytic cell. In the first cell, one half-cell has
stiks02 [169]

Au³⁺ metal ion is reduced in the Au/Cr cell and Co²⁺ metal ion is reduced in the Co/Zr cell

<h3>What is a voltaic cell?</h3>

A voltaic cell is a cell that generates electricity by a spontaneous redox reaction.

It is an electrochemical cell, also known as a galvanic cell and  

Electrical energy is created by converting chemical energy.

Examples of voltaic cells include the dry cell, nickel-cadmium cell, lead storage cell, and fuel cells.

The half-cell reactions for each cell are given by

Au^{3+}(aq) + 3e^- \rightarrow Au(s) ; E° = 1.50 V

Cr^{3+}(aq) + 3e^- \rightarrow Cr(s) ; E° = –0.74 V

Co^{2+}(aq) + 2e^- \rightarrow Co(s) ; E° = –0.28 V

Zn^{2+}(aq) + 2e^- \rightarrow Zn(s) E° = –0.76 V

Thus, Au³⁺ is reduced in the Au/Cr cell and Co²⁺ is reduced in the Co/Zr cell
