Electron
Atoms, compounds, and molecules undergo chemical reactions to form new substances. In general, reactions proceed to produce products which are have more stability.
These chemical reactions are possible because of the ability of substances to form chemical bonds with other substances. These formation of bonds are primarily attributed to electronic interactions (i.e. the valence or outer electrons of the atoms). of substances.
Atoms are able to form new substances by gaining, losing, or sharing electrons with other atoms.
Force of friction is magnetic force
Answer:
Electrons are moved through a magnet, creating a current. That current interacts with a circuit, moving the conductor in the orientation of the field.
Explanation:
Electro magnetic fields are used to create electric current by the movement of electrons. When a coil of wire is wrapped around a magnet it pushes electrons and they flow through a magnet to create current. This current interacts with circuit to move conductor.
Sand and gravel mixture would be easiest to separate based on the size of the particles.
<h3>What are mixtures?</h3>
Mixtures are the composition which can be obtained by the combination of different types of elements.
In the question different types of mixtures are given in which all have same kind of size distribution except sand and gravel. Size of sand is smaller than gravel, so it can be separated by easy physical method like sieving.
Hence, option (d) is correct it means sand and gravel would be easiest to separate.

Answer is: Reactants: 2VCl2 and 3Cl2; product: 2VCl5.
Balanced chemical reaction: 2VCl₂ + 3Cl₂ → 2VCl₅.
According to principle of mass conservation, number of atoms must be equal on both side of chemical reaction.
There are ten chlorine atoms and two vanadium atoms on both side of balanced chemical reaction.
