how many atoms are in 2.5 moles of carbon.
Answer:
4.52*10^23 atoms in 2.5 moles of carbon.
Explanation:
multiply 2.50 mol CO2 by 3 atoms/1 mol CO2 before multiplying by 6.022*10^23 atoms/1mol atoms.
In 2.5 moles of Carbon (C) there are 12.53^23 atoms. This is arrived at by utilizing Avogadro's number.
What is a mole?Mole is short for molecules. Molecules are a combination of atoms.
What is the calculation for the solution above?To derive the number of atoms in 2.5 molecules of carbon, we need to divide it's weight in grams with the atom mass units.
To get the atomic mass units (amu) we need to check the periodic table.
Once the division is done, the result must be multiplied by Avogadro's number which is stated as 6.02 x 10^23.
Thus, the formula is given as:
amu = grams/mole; or
u = g/mole
Since the Molar Mass of Carbon is 12.01g/mol
The number of atoms will be
2.5/12.01 X 6.02 x 10^23.
= 0.20815986677768526228143213988343 x 6.02 x 10^23.
= 1.2531223980016652789342214820983 x 10^23.
= 12.531223980016652789342214820983^23.
≈ 12.53^23.
It is to be noted that the molar mass of carbon is derived from the Periodic Table.

Desertification is largely caused by poor land management (6 marks)
Desertification is the irreversible deterioration of once arable land, and it threatens a growing proportion of the Earth's surface as temperatures rise and the human population increases.
Drylands, including arid, semi-arid, and sub-humid regions, are of particular concern due to human-caused land degradation. However, the term "desertification" is often interpreted to mean something different. More than 40 percent of Earth's surface is made up of these drylands.
While degradation of land has occurred naturally throughout time, the current rate is 30–35 times faster than normal, as reported by the United Nations. Various human activities, including as urbanization, mining, farming, and ranching, are major contributors to this deterioration. When these actions are carried out, trees and other plants are cut down, animals' hooves trample the ground, and crops use up soil nutrients. Drought risks are exacerbated by climate change, which also plays a key influence.
All of these factors make the earth less able to hold water and regenerate plants, leading to soil erosion. There are around 2 billion people that rely on the drylands that are threatened by desertification, and it is predicted that as many as 50 million will be forced to relocate by the year 2030.

Which depositional landform is created at the ultimate base level (or terminus!) of a stream, where sediment is deposited into the sea?
Answer:
Peneplain.
Explanation:
The base level is the lower limit of the erosional process and the ultimate base level is the plains that result from the projection of sea level under the landmass. This process of erosion creates a peneplain. The base level is dynamic and changes according to the following factors as sea-level changes, tectonic factors, river captures, and sedimentation. Peneplinasare low featureless deposits that are created by the terminus of the dream where the sediments are merged with the sea.To measure a base lone, a steel stape 30m lang, Standardised at 15°C with a pull of 80N was used. find the correction per tape length, if the tempreture at the time of measurements is 25°c and the pull exerted is 150N. Take young's modulus E= 2X10^5 N/mm2 and coefficient of thermal expansion 211.2x10^6c°Cross-sectional area of tape is 8mm2
The correction of thermal expansion per tape length, if the temperature at the time of measurements is 25°c and the pull exerted is 150N is 4.67 ×10 ⁻³m.
Thermal expansion is the tendency of remembering to change in form, volume, and region in response to an alternate in temperature. Temperature is a monotonic characteristic of the common molecular kinetic power of a substance.
Given,
Length of steel tape = 30m
Temperature at standardization = 15°C
The temperature at the time of measurement = 25°C
Standardized pull (Po) = 80N
Pull exerted (Pm) = 150N
Young modulus of elasticity = E = E= 2X10^5 N/mm2
Coefficient of thermal expansion = 211.2x10^6c°
Cross-sectional area of tape = 8 mm²
For temperature correction Cm = (Tm - T₀)αL₀
Putting α = ( 25 - 15 ) × 11.2 × 10⁻⁶ × 30
Cm = 3.36 × 10⁻³ m
For full correction ;

Which side of Tallahassee principal meridian is range 1e
The Tallahassee Principal Meridian is a reference line used in the United States Public Land Survey System (PLSS) to demarcate land parcels. Ranges are divisions of land that run north-south, and they are designated by numbers. In this case, we have Range 1E.
To determine which side of the Tallahassee Principal Meridian Range 1E is located on, we need to understand how the PLSS works. The Tallahassee Meridian itself runs north-south, with all the ranges on the east side labeled as "E" and those on the west side labeled as "W."
Therefore, Range 1E of the Tallahassee Principal Meridian is situated on the eastern side of the meridian. This means that the land parcels within Range 1E are located to the east of the Tallahassee Meridian line.
The PLSS system provides a systematic way to describe and locate land parcels, enabling precise identification and management of property boundaries. By using the meridian and range system, land ownership, surveying, and legal descriptions become more accessible and accurate. The Tallahassee Principal Meridian, with its ranges and divisions, plays a crucial role in land administration and property rights in the region.

what is urban primacy?
Answer: Small countryz with small population
Answer:
Urban Primacy is when one city is dominantly large in a group of cities. For example, Thailand exhibits urban primacy because Bangkok is several times larger than the next largest city. Usually when a largest city is over twice as large as the next city, this would constitute urban primacy. Other measures are more rigorous whereby a city is only primate when it is at least 3 times larger than the next two cities combined. Primacy is almost always calculated using this kind of population-size ratio. Ideally metropolitan level populations are used so as to avoid dividing the largest city by an adjacent centre.
Boomtowns are developing in India as a result of
return migration
the outsourced IT sector
British colonialism
the primary economic sector
discoveries in gold and silver
Boomtowns in India are developing primarily as a result of two factors: the outsourced IT sector and the primary economic sector.
The outsourced IT sector: India has become a hub for IT outsourcing, with many global companies setting up operations in Indian cities. This has attracted a large number of skilled professionals and created job opportunities, leading to urban growth and the development of boomtowns.The primary economic sector: India's economy heavily relies on sectors such as agriculture, mining, and manufacturing. Rapid industrialization and agricultural growth have led to the emergence of boomtowns in areas where these sectors are thriving. Increased economic activities and employment opportunities drive population influx and urban expansion.While return migration, British colonialism, and discoveries in gold and silver have influenced India's history and economy, they are not the primary factors behind the development of boomtowns in the country. It is the combination of the outsourced IT sector and the growth of the primary economic sector that has played a significant role in the rise of boomtowns in India.

Explain the inequalities of the division of the north and the south.
The division between the North and the South refers to the historical and socio-economic disparities that existed in the United States before and during the American Civil War (1861-1865).
These inequalities encompassed various aspects such as economy, culture, politics, and social structures. Economically, the North was characterized by industrialization, commerce, and a diverse economy that included manufacturing, trade, and finance. On the other hand, the South relied heavily on agriculture, particularly cotton plantations worked by enslaved African Americans.
The Southern economy was primarily agrarian, with limited industrialization and dependence on cash crops. This economic divide led to stark differences in social structures and attitudes. The South upheld a plantation system that was based on slavery, resulting in a hierarchical society with a small class of wealthy plantation owners and a large population of enslaved people.
In contrast, the North had a more diverse population and was home to a growing middle class, with a greater emphasis on individual freedoms and wage labor. Politically, the differences between the North and the South became pronounced as issues of slavery, states' rights and economic policies came to the forefront.
The Northern states gradually shifted towards opposing slavery and supporting abolitionist movements, while the Southern states sought to protect and expand their institution of slavery. These divisions ultimately culminated in the American Civil War, as tensions reached a breaking point. The war was fought between the industrialized, anti-slavery North (Union) and the agrarian, pro-slavery South (Confederacy).

Mafic minerals would likely crystallize early from magma. The right answer is option 1.
Some of the silica in a mafic minerals interacts with iron and magnesium to form olivine as it begins to cool. The silica that is still present transforms into calcium-rich plagioclase as it cools more, and any silica that is still present may be used to turn some of the olivine into pyroxene.
Shortly afterwards, all of the magma is consumed, and nothing else changes. Gabbro will result from the magma cooling slowly beneath, while basalt will result from the magma cooling swiftly at the surface. When crystallisation first starts, felsic magmas are typically cooler than mafic magmas.
