Answer:
Representative Elements
Explanation:
Representative elements are chemical elements of the long groups of the periodic table identified by the letter A, headed by the elements hydrogen, beryllium, boron, carbon, nitrogen, oxygen, fluorine and helium, as they appear in the periodic table of the elements. .
They are characterized by presenting "external" electronic configurations in their fundamental state ranging from ns1 to ns2np6, unlike the transition elements and internal transition elements.
The representative elements are the elements of groups 1 and 2 (block s), and of groups 13 to 18 (block p) .2 Until a few years ago, these groups were identified with Roman numerals from I to VII with the letter A.3 The elements of group 12 are generally considered as transition metals, however, zinc (Zn), cadmium (Cd), and mercury (Hg) share some properties of both groups, and some scientists believe they should be included as representative elements or elements of the main groups.
Representative elements (with some of the lighter transition metals) are the most abundant elements on earth, in the solar system, and in the universe.
The representative elements are divided into eight groups and are characterized in that their electronic distribution ends in s-p or p-s. The group number results from adding the electrons in the sub-levels s or s and p of the last level.

The kinematics and geometry can locate the point where the earthquake occurs: Point of interception of the three circles
The earthquakes occur due to a sudden movement of two tectonic plates, this movement produces longitudinal and transverse waves with different speeds, called S and P waves. The speed of the waves is constant, so we can use the uniform kinematic movement relationship
v = d / t
Where v is the speed of the wave, d is the distance and t is the time.
The speed of the two types of waves is known, they depend on the material and type of wave varies between 4 and 7 km / S, the time is measured in the seismometers, for which we can calculate the distance.
For a seismometer, the calculated distance corresponds to a circle, so to locate the epicenter of the earthquake we must have a minimum of three earthquakes, the point of intersection of the circles is the place of occurrence of the event, see the attachment for a diagram of the process.
In conclusion, with kinematics and geometry we can locate where the earthquake occurs: Point of interception of the three circles

Answer:
Explanation:
First, let's review the ideal gas law, PV = nRT. In this equation, 'P' is the pressure in atmospheres, 'V' is the volume in liters, 'n' is the number of particles in moles, 'T' is the temperature in Kelvin and 'R' is the ideal gas constant (0.0821 liter atmospheres per moles Kelvin)
