Answer: The distribution of natural resources depends upon many physical factors like land, climate and altitude. The distribution of resources is unequal because these factors differ from place to place on this earth.

Many physical factors, such as land, climate, and altitude, influence the distribution of natural resources. Because these factors differ from place to place on this planet, the distribution of resources is unequal.

The Earth's surface is defined as the part of the water or land that comes into contact with the air above it. The surface is the part of the Earth with which we interact. The crust is the rock layer that surrounds the Earth's mantle. The crust encircles the entire planet, including the ocean floor.

The crust is the planet's surface, where we live; it's actually a very thin layer, only 70 kilometers thick at its thickest point.

Petroleum is formed by the same geological process that creates sedimentary rock. The geological processes that create rocks and natural resources such as granite and copper do not occur everywhere on Earth and take a long time to form. This explains why granite and copper aren't found everywhere on the planet.

Thus, Because these factors differ from place to place on this planet, the distribution of resources is unequal.

Answer:

Explanation:

When a comet enters the solar system it curves towards the Sun due to the Sun's gravitational pull. Every celestial object in the universe has a gravitational pull whose force is dependent on the object's mass. The larger the object is the more gravitational pull it will have. The Sun is the largest object in our Solar system and therefore has the most gravitational pull. This is why the comet curves toward the Sun, but the opposite does not happen because the comet's gravitational pull is not strong enough to pull the Sun.                  

Answer:

0.047

Explanation:

Data : 5g , Na2CO3

Formula:

Molecular mass of Na2Co3 = no.of atomic mass x no. of atom

moles = mass÷ molecular mass

molecular mass = 2(23)+1(12)+3(16)

=106amu

moles = 5÷106

= 0.047 Ans:

Answer:

The formula weight of the compound is

46.069 g/mol.

Explanation:

Determine the molar mass from the empirical formula (C2H6O) by multiplying the molar mass of each element in the compound by the number of atoms of it and adding the resulting masses of the elements:

molar mass of C2H6O = (2 × 12.011 g/mol) + (6 × 1.008 g/mol) + (1 × 15.999 g/mol) = 46.069 g/mol.

The chemical formula of CO, Fe₂O₃, and C₂H₄ contain atoms of two different elements. Therefore, option (D) is correct.

A chemical formula provides information about the chemical proportions of atoms of each element that are present in a molecule or chemical compound. The chemical formula can be represented by using chemical symbols of elements, numbers (subscripts), and other symbols, such as commas, dashes, brackets, and plus (+) and minus (−) signs.

A chemical formula of a compound has no words but can be written in certain simple chemical structures. Chemical formulae can be more limited in power than chemical names and structural formulae. There are two kinds of chemical formulas in which one empirical formula and another molecular formula.

In the chemical formula of carbon monoxide (CO) has carbon and oxygen two different elements. In the chemical formula of iron oxide (Fe₂O₃)  iron and oxygen are two different elements. In the chemical formula of ethane (C₂H₄ ) has carbon and hydrogen two different elements.

Answer:

The freezing point depression ∆T = KF·m where KF is the molal freezing point depression constant and m is the molality of the solute. Rearrangement gives: mol solute = (m) x (kg solvent) where kg of solvent is the mass of the solvent (lauric acid) in the mixture. This gives the moles of the solute.

Explanation:

Why is glycerol more viscous than water?

The glycerine is more viscous than water because due to presence of hydrogen atoms , we all know that glycerine has more hydrogen bonding than water molecule , which makes an aggregation which means that glycerine is more viscous than water , in simple words glycerine can't flow as that of water molecule.

Answer:

2.00

Explanation:

From Graham's law; the rate of effusion is inversely proportional to the square root of the relative molecular mass.

Let the rate of effusion of Helium be R1

Let the rate of effusion of Methane be R2

Let the molecular mass of Helium be M1

Let the molecular mass of Methane be M2

Hence;

R1/R2 = √M2/M1

R1/R2 = √16.0294/4.0026

R1/R2 = 2.00

Answer: 322.56 Kelvin

Explanation:

Use the Ideal Gas Law

R is the gas constant

T is the temperature in Kelvins

P is the pressure in atmospheres

V is the volume in liters

n is the number of moles of gas

First, the mm of mercury need to be converted to atmospheres using the conversion factor 1atm = 760 torr.

[tex]751.2mmHg (torr) =0.988atm[/tex]

Now plug everything in

[tex](0.988)(26)=(0.97)(0.0821)T\\T=322.56K[/tex]

B : 4.6 billion years

Credits go to the person above me.

;)

Explanation:

EDGE 2021

The sun is about 4.6 billion years old. Therefore, option (B) is correct.

The Sun is made primarily of the elements hydrogen and helium. They account for 74.9% and 23.8% mass of the Sun in the photosphere. All heavier elements, called metals account for less than 2% of the mass, with oxygen (<1%), carbon (0.3%), neon (0.2%), and iron (0.2%) being the most abundant.

The hydrogen and helium in the Sun would have been produced by Big Bang nucleosynthesis and the heavier elements were produced by former generations of stars before the Sun was formed.

The amount of helium and its location within the Sun has gradually changed over the past 4.6 billion years. The proportion of helium has raised from about 24% to 60% due to fusion, and some of the He and heavy elements have settled from the photosphere toward the center due to gravity.

Therefore, the age of the sun is about 4.6 billion years.
