The best choice that explains why atoms of carbon-14 (c-14) are unstable is there are 2 more protons than neutrons in the nucleus
<h3>
What is a stable atom?</h3>
An atom is said to be stable if the number of neutrons in the nucleus is greater than number of protons in the nucleus, because the the neutrons increases the nuclear force which keeps the atom stable.
Thus, the best choice that explains why atoms of carbon-14 (c-14) are unstable is there are 2 more protons than neutrons in the nucleus.

The magnetism is either created inside a given element by passing some number of charges,Q across it or it is due to the interaction with a permanent magnet.
<h3>What is Magnetism ?</h3>
A physical phenomenon produced by the motion of electric charge, which results in attractive and repulsive forces between objects.
The magnet consists the characteristics of having an optimum amount of energy (P.E inside it) inside it.
As, the energy lines are either directed outwards from the north pole of the magnet, the south pole of the magnet consumes or absorbs the magnetic rays(energy lines) originated from the north pole of the magnet.
- The right hand rule of magnetism is illustrated in the 12 point of the question.
As the right hand rule says that there will be a net amount of magnetic field around the conductor or any current carrying element in a specific direction.
Now, the current carrying direction of the wire is in perpendicular direction to that of the magnetic field created.
- Point No.15 of the given question provides us the information regarding the idea of left hand rule of magnetism.
As, due to the contact between the magnetic fields.
- The fillings are separated from the magnets in the given experiment due to the fact there is a source for covering up the particles from getting too much exposed to the magnetic field. But, they are not able to stop the magnetic line of force,F from not penetrating its surface.
- The iron fillings are present there to have a complete bridged form of connections between itself and the horseshoe magnet.
As the horseshoe magnet and the iron fillings are placed in a specified form of orientation inside the given space or region of interaction.

Answer:
712 moles of Hg are produced
Explanation:
Based on the reaction:
2HgO → 2Hg + O₂
<em>Where 2 moles of HgO reacts producing 2 moles of Hg and 1 mole of O₂</em>
<em />
To solve this question we need to find the moles of Hg produced, then, using its molar mass:
<em>Moles Hg:</em>
3.55mol HgO * (2 mol Hg / 2 mol HgO) = 3.55 mol Hg
<em>Grams -Molar mass Hg: 200.59g/mol-:</em>
3.55mol Hg * (200.59g/mol) =
712 moles of Hg are produced

pretty sure It's correct and if it is then your welcome
