Answer is: charges are balanced during redox.
1) False. Electrons are produced on zinc rod (Zn → Zn²⁺ + 2e⁻)
2) False. Electrons flow from anode (negative electrode) to cathode (positive electrode).

The energy released in nuclear reactions are far larger than that released in chemical reactions due to the release of nuclear energy from the nucleus.

<h3>Why is the energy released in a reaction?</h3>

Energy is released in a reaction due to the breaking of bonds are well as formation of bonds.

The quantity of energy released in reactions differs according to the reaction type involved.

When compared to chemical reactions, the energy released in nuclear reactions are very much higher because of the changes that occurs in the nucleus of the atoms involving nuclear energy.

The energy, E released in nuclear reactions is given by the formula below:

$E = mc^{2}$

where m is the mass of the substance and c is the speed of light.

Therefore, the energy released in nuclear reactions are far larger than that released in chemical reactions.

Scientists learn about the properties of some particles from the collisions that occur inside a blank

Thepotemich [5.8K]

Answer:

Gases consist of very large numbers of tiny spherical particles that are far apart from one another compared to their size. Gas particles are in constant rapid motion in random directions. Collisions between gas particles and between particles and the container walls are elastic collisions.
