Explanation:
Gold: The Kolar Gold Fields in Kolar used to be one of the major producers of gold in India, before it shut down. Presently the gold mines of Hutti and Raichur produce almost 84 per cent of the country’s gold. The other major centers of gold mining are Dharwad and Chitradurga. The gold mines produce about 3,000 kg’s of gold per annum. The district of Raichur is also famous for its silver deposits.
Limestone: It is another important mineral with an estimated 51,000 million tons. Karnataka has the largest limestone reserve in India. The districts of Gulbarga, Bagalkot, Belgaum, Shimoga and other Uttara Kannada districts are endowed with extensive high grade limestone. The present and consistent production of approximately 14 million tonnes provides for the cement plants in these districts.
China clay (kaolin) consisting dominantly of kaolinite is one of the most sophisticated industrial minerals with a host of applications, viz., in ceramics, refractories, paper coating, filler for rubber, insecticides, cement, paint, textiles, fertilizers and others including abrasives, asbestos products, fibreglass, chemicals, cosmetics, pharmaceuticals, electrical ware, foundry and glass.
The Department of Mining and Geology through their past investigation campaigns in parts of Kerala,identified two major china clay zones viz., the southern china clay zone between Thiruvananthapuram and Kundara (Thiruvananthapuram and Kollam districts) and the northern china clay zone between Kannapuram Madayi -Cheruthazham in Kannur district to Nileswarm - Manjeshwaram in Kasargod district. An estimated reserve of 172 million tonnes (probable reserve of 80 million tonnes and possible reserve of 92 million tonnes) of china clay of sedimentary and residual origin has been arrived at.
Kerala china clay is one of the finest quality clay and is world class. In fact, Kaolin marketed by English Indian Clays Ltd. (EICL), Thiruvananthapuram claims to have similar or even better properties compared to imported clays.

Calculate the pOH and the pH of a 5.0 x 10-2 M solution of NaOH.
Answer:
pOH = 1.3, pH = 12.7
Explanation:
Since NaOH is a strong base, it will completely ionize; further, since it completely ionizes, our hydroxide concentration (a product of the ionization) will be the same as the given concentration of NaOH.
NaOH -> Na⁺ + OH⁻, [OH⁻] = 5.0 x 10^-2 M
pOH is the negative log of the hydroxide concentration, so plug our hydroxide concentration in:
pOH = -log[OH⁻] = -log[5.0 x 10^-2 M] = 1.3
Since pH + pOH = 14, we can plug in pOH and solve for pH:
pH + 1.3 = 14
pH = 14 - 1.3 = 12.7
Thus, our pOH = 1.3 and pH = 12.7.

A 1.5 L pocket of air with a temperature of 295 K rises in the atmosphere. What will be the volume of the air pocket of the t temperature decreased to 2 celsius and the pressure is not changed.
Answer:
1.4 L.
Explanation:
Applying Charles law,
V/T = V'/T'....................... Equation 1
Where V = Initial volume, V' = Final volume, T = Initial Temperature in Kelvin, T' = Final Temperature in Kelvin.
Make V' the subject of the equation
V' = (V/T)T'..................... Euqation 2
Given: V = 1.5 L, T = 295 K, T' = 2 °C = (2+273) K = 275 K
Substitute these values into equation 2
V' = (1.5/295)275
V' = 1.398
V' ≈ 1.4 L
1.9x10^23 atoms of sulfur to grams of sulfur
Answer:
see explanation and punch in the numbers yourself ( will be better for your test)
Explanation:
If you are given atoms you need to divide by Avogadro's number 6.022x10^23
then you will have moles of sulfur-- once you have moles multiply by the molar mass of sulfur to go from moles to grams
mm of sulfur is 32 g/mol
Mole measure the number of elementary entities of a given substance that are present in a given sample. Therefore, the grams of sulfur in 1.9x10²³ atoms of sulfur is 9.92g.
What is mole?The SI unit of amount of substance in chemistry is mole. The mole is used to measure the quantity of amount of substance.
Given number of atoms= 1.9x10²³atoms
we know one mole of any element contains 6.022×10²³ atoms which is also called Avogadro number
mole =given number of atoms ÷ 6.022×10²³(Avogadro number)
Substituting the values
mole=1.9x10²³÷ 6.022×10²³
mole = 0.31 mole of sulfur
Mole = given mass÷ Molar mass
Molar mass of sulfur=32g/mol
mass of sulfur =0.31 mole ×32g/mol
mass of sulfur=9.92g
Therefore, the grams of sulfur in 1.9x10²³ atoms of sulfur is 9.92g.

Plate Tectonics Independent Practice,
Label The Diagram With The Correct Information.
Answer:
1st Diagram (at the left) → Mid-Atlantic Ridge
2nd Diagram (at the right) → Andes Mountains
3rd Diagram (below) → San Andreas Fault
Explanation:
I have been able to label the diagram with the correct information.
The 1st diagram at the left is the Mid-Atlantic Ridge. This is a divergent plate boundary that is found at the floor of the Atlantic Ocean. It is also seen as part of the mountain range in the world. The Mid-Atlantic Ridge also includes a deep rift valley. This rift valley runs along the axis of the ridge. This is along nearly its entire length.
The Andes Mountains is found along the Pacific Ring of Fire. It is seen in a Mesozoic–Tertiary orogenic belt of mountains. The Andes rises due to the compression of the western rim of the South American Plate. It is a result of tectonic plate processes.
San Andreas Fault is known to form the tectonic boundary which exists between the Pacific Plate and the North American Plate. The motion of the fault is right-lateral strike-slip. It divides into three segments.

Would a rollercoaster have the greatest kinetic energy at the top of the highest hill or at the bottom on the highest hill
Answer:
The rollercoaster has the lowest kinetic energy at the top of the hill.
The rollercaoster has the highest kinetic energy at the bottom of the hill.
Explanation:
The kinetic energy of any solid body in motion is usually computed using this formula:
K.E = [tex]\frac{1}{2}mv^2[/tex]
From this, we can see that it varies based on two major parameters - The mass of the moving object and the velocity of the moving object.
We can assume that the mass of the rollercoaster is constant since no one gets off and it does not shrink in its size during the ride.
This means that the variations in the K.E are mainly coming from its velocity.
At the top of the hill, the rollercoaster is moving at its slowest pace. hence, it has the lowest kinetic energy at the top of the hill.
However, at the bottom of the hill, the rollercoaster is moving its fastest, hence it has the highest kinetic energy at the bottom of the hill.
In an effort to sanitize his water, Beethoven knows that bromine can be used to purify water. If Beethoven has 2.12 x 1022 formula units of aluminum bromide are reacted with excess chlorine gas, how many milliliters of liquid bromine (density = 3.12 g/mL) are formed?
Answer:
2.7 mL
Explanation:
The equation of the reaction is;
2AlBr3 + 3Cl2 -----> 2AlCl3 + 3Br2
Number of moles in 2.12 x 1022 formula units of aluminum bromide
1 mole of AlBr3 = 6.02 * 10^23 formula units
x moles = 2.12 x 1022 formula units
x = 2.12 x 1022 formula units * 1 mole/ 6.02 * 10^23 formula units
x = 0.0352 moles of AlBr3
According to the reaction equation;
2 moles of AlBr3 produces 3 moles of Br2
0.0352 moles of AlBr3 produces 0.0352 moles * 3 moles /2 moles
= 0.0528 moles of Br2
Mass of Br2 produced = 0.0528 moles of Br2 * 159.808 g/mol
Mass of Br2 produced = 8.44g
But density = mass/volume
volume = mass/density
volume of Br2 = 8.44 g/ 3.12 g/mL
volume of Br2 = 2.7 mL

El mercurio ha sido utilizado como elemento para medir la temperatura porque Es una mezcla. Al aumentar la temperatura se dilata con facilidad. Es un buen conductor del calor. Es un buen conductor de la electricidad.
Answer:
La respuesta correcta es: Al aumentar la temperatura se dilata con facilidad
Explanation:
El mercurio (Hg) es un elemento metálico que a temperatura ambiente es un líquido. Tiene la propiedad de dilatarse con facilidad al aumentar la temperatura, propiedad que ha sido utilizada en los termómetros de mercurio. En estos termómetros, el mercurio está dentro de un tubo de vidrio graduado con un bulbo para transmitir el calor. Al estar en contacto con un cuerpo más caliente (a mayor temperatura), el mercurio del interior del termómetro se dilata (expande su volumen) y asciende por el tubo indicando la temperatura correspondiente, graduada en el vidrio.

Describe the composition of a molecular compound. What are two major characteristics of molecular compounds?
Answer:
A molecular compound is composed of two or more non metallic elements that are held together by covalent bonds.
The two major characteristics of molecular compounds are;
1.) They are held by covalent bonds
2.) They generally have poor conductivity
Explanation:
A molecular compound is one where two or more molecules come together to form a compound. Unlike ionic compounds that combine by the transfer of electrons, molecular compounds form by sharing electrons. The pairing of the electrons is what holds the molecules together and is known as covalent bonding.
A molecular compound has various characteristics, some of which are;
- Generally low melting and boiling points
- Soft solid forms
- Low enthalpy of fusion and vaporization.
But the two major characteristics of molecular compounds are;
1.) They are held together by covalent bonds.
The elements in a molecular compound share their electrons by having their atoms bond chemically to each other.
2.) They generally have poor conductivity
Molecular compounds do not conduct electricity and heat properly. Because they are formed by sharing electrons, they usually have no free electrons left to conduct electricity.

Explanation:
When we are writing chemical reaction equations, we must ensure that such equations are balanced. That is, the number of atoms of each element on both sides of the reaction equation are exactly the same.
After we identify the formula of each compound in the reaction, then we proceed the write the balanced reaction equation as follows;
