The valency of iron (Fe) in this equation is 2
While, the valency of chlorine is 1
Therefore, we know that iron wants to give away 2 electrons to attain octet configuration, and chlorine wants to get an electron to attain octet configuration.
Also while find the products the number of atoms is similar to the oppostie valency
Fe = 1 atom , Cl = 2 atoms
Which will form FeCl₂
Happy to help :)

Answer:
376.56
Explanation:
using the formula q=mcΔT, where m=15g, C=4.18J/g°C and ΔT=6.0°C
The electron has a higher frequency compared to the neutron. It can be explained by the way an electron orbits the nucleus of an atom.
According to Quantum Mechanics, electrons do not really orbit the nucleus of an atom. In fact, the most tightly bound state, the 1s orbital, has no angular momentum at all. This would be the state with the most "kinetic energy" and yet there is no "orbital" motion at all in this state.
<span>However, there are frequencies associated with each orbital.

Answer:
Option D. The total amount of both matter and energy does not change.
Explanation:
From Law of conservation of energy and Einstein's mass-energy relation, we know that, energy neither is formed not is destroyed. It converts from one form to another. Einstein's mass-energy relation: E = mc². It means, Matter is a form of energy i.e. matter holds energy equivalent to product of its mass and square of speed of light. Matter and energy can change forms but the total amount does not change in a closed system. Thus, correct option is D.
