The region around a magnet where the magnetic force is exerted is known as magnetic field<span>. Magnetic field is the area around a magnet, a magnetic object or an electric charge in which magnetic force is exerted. Magnetic fields are created by moving electric charge. Magnetic field is measured by its strength and by the direction it points. The strongest external magnetic fields are near the poles. A magnetic north pole will attract the south pole of another magnet, and repel a north pole. In a bar magnet the magnetic field lines can be traced out with the use of a compass.</span>
Answer:
A decrease in the total volume of the reaction vessel (T constant)
Explanation:
- Le Châtelier's principle predicts that the moles of H2 in the reaction container will increase with a decrease in the total volume of the reaction vessel.
- <em><u>According to the Le Chatelier's principle, when a chnage is a applied to a system at equilibrium, then the equilibrium will shift in a way that counteracts the effect causing it.</u></em>
- In this case, a decrease in volume means there is an increase in pressure, therefore the equilibrium will shift towards the side with the fewer number of moles of gas.
Answer:
The answer is B
Explanation:
Because conduction of heat or electricity occurs through a medium(for eg. The heat from a fire going through a metal pot . So in this example the pot is the medium of conduction).
And in this question the medium of heat conduction is the ground, with the heat moving in an upward motion .
The atoms of different chemical elements can be differentiated based on the number of protons.
Each chemical element is differentiated by his number of protons. This number of protons is also knowing as atomic number and it is represented by the letter (Z).
The atomic number represented the number of protons in the nucleus of an element. For example:
- The element that has only 1 proton in his nucleus is Hydrogen atom.
- The element that has 2 protons in his nucleus is Helium atom.
<h3>What is an atom?</h3>
The atom is the smallest part of the composition of matter, it is indivisible and is composed of a nucleus that has protons and neutrons, and around the nucleus there are the electrons.
