What is soil ?
The soil is nothing but a mixture that contains minerals, organic matter, and living organisms, it is a loose sediment. Moreover, there are different types of soil such as Clay Soil, Sandy soil, Loamy Soil, Silt Soil
soil composed of 45% minerals, 50% spaces or voids and 5% organic matter, it performs many important functions such as Providing a growth medium for the plants, Acts a modifier of the earth’s atmosphere and it is One of the most crucial components of the biosphere
The formation of soil occur by weathering of rocks. the weathering of Solid rock can weather occur in three way such as Mechanical Weathering, Chemical Weathering, Biological Weathering

An alcohol thermometer makes use of alcohol's changing in order to measure temperature. As the temperature goes up.
the alcohol contained in the thermometer increases in volume, filling more of the thermometer's tube.
A. state
B. mass
C. density
D. chemical composition
The question is incomplete, the complete question is;
An alcohol thermometer makes use of alcohol's changing _______ in order to measure temperature. As the temperature goes up, the alcohol contained in the thermometer increases in volume, filling more of the thermometer's tube.
A.
mass
B.
state
C.
chemical composition
D.
density
Answer:
D.
density
Explanation:
Every kind of thermometer makes use of a change in a particular physical property of a substance as a measure of temperature. It must be a property that changes with temperature.
Density of a substance changes with temperature. Even though the mass of alcohol in glass remains constant, but its volume increases or decreases with change in temperature leading to a change in volume and consequently a change in density of the alcohol in glass. This change is used as a measure of the change in temperature.
Why are noble gases, like helium and krypton, unlikely to form a bond?
A. They do not have valence electrons and therefore cannot form bonds by sharing or trading
electrons.
B. They always have an equal number of protons and electrons.
C. They have full valence
orbitals and already have low energy.
D. They are nonmetals and gases and therefore their ionization energy is too high to form a bond.
Answer:
The valence electrons are the only parts of an atom that make chemical bonds. Noble gases don't form chemical bonds because they have a full outer shell (8 electrons).

how many atoms are in 0.340 moles of sodium
The number of atoms that are in 0.340 moles of sodium is 2.047×10²³ atoms.
What is Avogadro's number?Avogadro's number is equal to 6.022×10²³ which gives idea about the number of atoms present in one mole of any substance.
i.e. In 1 mole = 6.022×10²³ atoms
Given moles of sodium = 0.34 mol
Number of atoms of sodium in given moles will be calculated as:
No. of Na atoms = 0.34mol × 6.022×10²³ atoms/mol = 2.047×10²³ atoms
Hence required number of atoms are 2.047×10²³ atoms.

Dinitrogen pentoxide is used in the preparation of explosives. If 7.93 mol of
dinitrogen pentoxide undergoes simple decomposition, what volume of Oz(9) is
produced at 48.0 °C and 125 kPa?
The volume of O₂ produced: 84.6 L
Further explanationGiven
7.93 mol of dinitrogen pentoxide
T = 48 + 273 = 321 K
P = 125 kPa = 1,23365 atm
Required
Volume of O₂
Solution
Decomposition reaction of dinitrogen pentoxide
2N₂O₅(g)→4NO₂(g)+O₂ (g)
From the equation, mol ratio N₂O₅ : O₂ = 2 : 1, so mol O₂ :
= 0.5 x mol N₂O₅
= 0.5 x 7.93
= 3.965 moles
The volume of O₂ :

What kind of fossil is made when a creature is buried under sediment and as that sediment forms into rock the hard materials like bones of the organism are formed into the rock?
Answer:
Mold fossil
Explanation:
It's called a mold fossil because they are formed when sediments bury an organism and then the sediments are changed into rock; then the organism decays thereby leaving a cavity in the shape of the organism

What type of plate boundary (divergent, convergent, or transform) is typically
associated with sliding or shear forces?
convergent
transform
divergent
Answer:
transform
Explanation:
The type of plate boundary associated with sliding or shear forces is a transform plate boundary.
Two or more plates slides laterally past one another due to presence of shear forces acting on them.
In this margin, there is often an occurrence of earthquake. For a divergent margin, plates move apart and away from one another. This leads to the creation or formation of new crusts. At a convergent margin, two plates collides, a plate can subduct under another or both can become uplifted. Tectonic margins are known for their various activities.Answer:
convergent

When scientists create a representation of a complex process, they are
inferring
c. classifying
b. predicting
d making models.
a.
Please select the best answer from the choices provided
А.
B
D
Answer:
d making models.
Explanation:
When scientists create a representation of a complex process, they are inferring that they are making models.
A model is an abstraction of the real world or a complex process. Models are very useful in developing solutions to processes that are not easily simplified.
The models allow a part of a body to be simply studied. Through this simple abstraction, extrapolations to other parts of the system can be deduced. This can give very useful insights into the other parts of the system. The heterogeneity of complex processes is a huge limitation to understanding them. A homogenous part can be modelled and used to understand the system.Answer:
D. making models.
