How many valence electrons are in two fluorine atoms
olga nikolaevna [1]

Answer:

If both fluorine atoms are combine than each atom have 8 valance electrons and total valance electrons in both atoms are 16.

Explanation:

Fluorine is halogen atom. The elements of group 17 are called halogens. These are six elements Fluorine, Chlorine, Bromine, Iodine, Astatine. Halogens are very reactive these elements can not be found free in nature. Their chemical properties are resemble greatly with each other. As we move down the group in periodic table size of halogens increases that's way fluorine is smaller in size as compared to other halogens elements.

There seven valance electrons in each halogen atom. They need one electron to complete the octet.

Fluorine atom combine with its another atom through covalent bond and share its one of valance electron with other atom thus both have 8 valance electrons and total valance electrons in both atoms are 16.

What are the three hypotheses that were proposed to explain the seismic activity of Pinatubo? What process generates sulfur diox
ASHA 777 [7]

Answer:

Mt. Pinatubo is one of the contrasting volcanoes that erupted violently in the year 1991, being the second strongest volcanic eruption that took place on earth in this entire century.

The 3 hypothesis that was proposed in order to describe the seismic activity of Pinatubo includes-

  • The magma rising upward to the surface from the interior of the earth, erupting through the crater of the volcano.
  • The eruption led to the releasing of a large number of volcanic gases into the atmosphere.
  • The earthquakes are produced due to the continuous tectonic activities that are primarily caused when the earth's crust moves over the layer of viscous asthenosphere.

A large number of volcanic gases are released such as sulfur dioxide (SO₂), methane (CH₄), Hydrogen sulfide (H₂O), Carbon monoxide (CO), and other gases, due to the formation of convection currents and rising up of magma from the mantle, creating volcanic eruptions at the surface

To what pressure must a gas be compressed in order to get into a 3.00 cubic foot
Troyanec [42]

Answer:

133.3atm

Explanation:

Given parameters:

Initial volume  = 400ft³

Final volume  = 3ft³

Initial pressure = 1atm

Unknown:

Final pressure  = ?

Solution:

To solve this problem, we  apply Boyle's law which states that "the volume of a fixed mass of a gas varies inversely as the pressure changes if the temperature is constant".

  Mathematically;

               P₁V₁ = P₂V₂

P and V are pressure and volume

1 and 2 are initial and final states;

   Insert parameters and solve;

                1 x 400  = P₂ x 3

                     P₂  = 133.3atm
