atroni [7]
Particle      mass                          charge                     location

protons     1.673*10 ^ - 27 kg        1.6*10 ^ -19 C        in the nucleus
neutrons   1.675*10 ^ - 27 kg        0                             in the nucleus
electron     9.11 * 10 ^ - 31 kg       -1.6 * 10 ^ - 19 C    around the nucleus (orbitals)

Protons and neutrons have almost same masses. Mass of electrons is 1/1840 the mass of the protons.

Protons and electrons have the same magnitud of charge with different sign. Protons are positive and electrons are negative. Neutrons do not have charge.

Describe the kinetic, potential and thermal energy of each state of matter?
Lerok [7]

Answer:

Particles of matter possess energy called kinetic energy.

Solid cannot be compressed, but gases are highly compressible.

The Kinetic energy of molecules of gases is very large & solids the least.

On heating a sublimable liquid, the molecules break free & escape from the surface of the solid directly into vapour.

Particles of matter move more rapidly on the application of heat

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

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
