which statement describes the energy and bonding changes as two atoms of fluorine become a molecule of fluorine?
Answers
Statement that gives description as regards energy and bonding changes between atoms such as fluorine become a molecule of fluorine, bond Energy is released as a bond is formed. Thus option 4 is correct.
What is bond energy ?The Bond Energy otherwise called as bond enthalpy is a quantity that offers insight into the strength of a chemical bond.
The ‘bond energy’ can also be represented as “the average value obtained from the bond dissociation enthalpies of all the chemical bonds in a given chemical compound.
The bond energy of a chemical bond is directly proportional to the stability of that bond which implies that the greater the bond energy o between two atoms, the greater the stability of that chemical bond.

What will be the volume occupied by 100 grams of oxygen gas
at STP?
Answers
Answer:70L
Explanation:
The volume occupied by 100g of oxygen gas at STP is 70L.
1 mole of a gas at STP occupies 22.4 L volume.
The same goes for oxygen gas, [tex]O_2[/tex]. 1 mole of [tex]O_2[/tex] occupies 22.4L volume.
Now the molar mass of [tex]O_2[/tex] is = 32g
So the number of moles of [tex]O_2[/tex] in 100g is
n = 100/32
n = 3.125 moles
Volume occupied by 3.125 moles or 100g of [tex]O_2[/tex] is
V = 3.125 × 22.4 L
V = 70 L volume is occupied by 100g of oxygen gas.

g 8. A hydrogen atom is initially a rest and in the ground state. A proton with kinetic energy 1000 eV scatters off the atom. In the process the hydrogen atom is ionized. The kinetic energy of the ionized electron is measured to be 15.2 eV and the kinetic energy of the proton produced from the ionization of hydrogen is 4.3 eV. What would be the final kinetic energy of the projectile proton after the collision
Answers
Answer:
Explanation:
Ionization energy of hydrogen atom is 13.6 eV . This energy will be provided by energetic proton , the kinetic energy of which is 1000 eV. The kinetic energy of ionized electron is 15.2 eV . Kinetic energy of proton produced from from the ionization of hydrogen or the nucleus of the hydrogen atom is 4.3 eV . All these energy must have come from kinetic energy of initial proton.
So kinetic energy of projectile proton after collision
= 1000 - ( 13.6 + 15.2 + 4.3 ) eV.
= 966.9 eV .

C. Transform boundary.
D. Convergent boundary
Answers
A valley or depression between continents is called Ocean basin. Therefore, the correct option is option A.
What is valley?A valley is indeed a long, low region that commonly runs between mountains or hills and has a river and stream that runs through one end to another. Most valleys are produced through long-term erosion of the ground surface by streams or rivers. Some valleys are produced by glacial ice erosion.
These glaciers may persist in valleys in mountainous areas or in polar regions. These glacially produced valleys could have been constructed or extended during ice periods at lower latitudes or elevations, but they are currently ice-free and populated by rivers or streams. A valley or depression between continents is called Ocean basin.
Therefore, the correct option is option A.

Why do not all rock types contain fossils?
Excessive heat and pressure can destroy fossils.
Fossils can only be created in certain places around the world.
Fossils cannot be created near volcanoes.
Fossils are too large to be found in igneous and metamorphic rocks.
Answers
Answer:
Igneous rocks form from molten rock, and rarely have fossils in them. Metamorphic rocks have been put under great pressure, heated, squashed or stretched, and fossils do not usually survive these extreme conditions. Generally it is only sedimentary rocks that contain fossils.
