Separating sand and salt by filtration and evaporation, what are the observations in the experiment?

Answers

Answer 1

While Separating sand and salt by filtration and evaporation, the observation is during the filtration the sand gets accumulated in the filter paper while separating it from the salt solution, while in evaporation the salt gets accumulated.

When we tried to separate the individual components from the mixture of the salt and sand the first step is dissolving the mixture in water as the salt gets dissolved so it is easy for us to filter the sand from the solution, it is followed by the method of evaporation, in which the filtered salt solution is boiled until the water gets evaporated and we are left with the salt,  that's how salt and sand are separated from a mixture.

Use the atomic mass of indium to calculate the relative abundance of indium-113.

Answers

The relative abundance of indium-113 is 4%.

The isotopes are species of the same element having the same atomic number but a different mass number.

The elements occurring in nature exist as multiple isotopes.

When we take into account the existence of these isotopes and their relative abundance (percent), the average atomic mass of that element can be computed, which is given by the following formula,

Average atomic Mass= (%age of isotope 1) x (Mass of isotope 1) + (%age of isotope 2) x (Mass of isotope 2)/100

Indium exists in the form of Indium-113 and Indium-115.

The mass of Indium-113 is 112.90 u.

The mass of Indium-115 is 114.90 u.

The average atomic mass of Indium is 114.82 u.

Let the %age of isotope 1(Indium-113) be X.

Then, the %age of isotope 2(Indium-115) would be 100-X.

Applying the values in the formula,

Average atomic mass = 112.90X+114.90(100-X)

114.82 = 112.90X+114.90(100-X)

On solving the above equation, the value of X comes out to be 4%.

Thus, the relative abundance/%age abundance of Indium-113 is 4%.

A video shows the objects in the solar system orbiting the sun. Why do objects orbit the sun?

A:The sun is so massive that it creates gravity.

B:The sun is so bright that objects are forced away.

C:The sun is releasing heat and pushing objects away.

D:The sun is moving so quickly that other objects move around it

Answers

Objects orbit the sun because the sun is so massive that it creates gravity, hence, option A.

According to Sir Isaac Newton, all objects, big or small, are attracted to each other by a force. This force could be strong or weak, depending on the size of the objects and the distance between the two objects. This force is called gravity.

The force of gravity can be felt here on earth. It is the force that is constantly pulling everything towards the center of the earth. However, for an object as massive as the sun, the gravitational field it creates is so strong that it constantly pulls all the planets towards itself. Due to inertia, the planets don't just fall in a straight line towards the sun. Instead, they trace a circular path around the sun called an orbit.

The force of gravity gets weaker as the distance between two objects increase. Hence, planets far away from the sun tend to move slower than planets closer to the sun.

It is also called solar system model of atom.

What is solar system model of atom?

The “solar system” model indicates an atom as a whole massive positive body that is the nucleus similar to the sun in the solar system with negative entities that are the electrons as the planets in our solar system revolving around it.

Why this model not accepted?

The thought about this model is that the electrons which revolves around the nucleus are the charged particles which have centripetal acceleration during the revolution. Even if they all are travelling at the same velocity in modulus, the trajectory of their velocity varies with respect to time which resulting in the centripetal acceleration. An accelerated charge particle will emit energy in the form of electromagnetic radiation. This results in the loss of energy which causes the charged particle to fall inside the nucleus. Therefore, this fails to happen.

Thus, we concluded that In 1897 the theory of understanding the energetics and arrangement of atoms was developed.

Gold can be hammered into extremely thin sheets called gold leaf. An architect wants to cover a 100 ft x 28 ft ceiling with gold leaf that is five-millionths of an inch thick. The density of gold is 19.32 g/cm^3, and gold costs $1654 per troy ounce ( 1 troy ounce =31.1035 g). How much will it cost the architect to buy the necessary gold?

Answers

Based on the calculations, it would cost the architect $33,940.08 to buy the necessary gold.

What is density?

Density can be defined as a ratio of mass to the volume of an object such as a baseball. Mathematically, the density of a baseball can be calculated by using this formula:

Density = M/V

Where:

M represents the mass of a physical object.V represents the volume of a physical object.

How to determine the cost of gold needed?

First of all, we would determine the volume of gold that is required in cubic centimeters as follows:

Conversion factor:

12 inches = 1 foot

Volume = 100 × 12 × 28 × 12 × 5 × 10⁻⁶

Volume = 2.016 in³

In cubic centimeters, we have:

Volume = 2.016 × 2.54³

Volume = 33.04 cubic centimeters.

Next, we would determine the mass of gold required:

Mass = Density × Volume

Mass = 19.32 × 33.04

Mass = 638.33 grams.

Converting the mass in grams to troy ounces, we have:

Mass = 638.33/31.1035

Mass = 20.52 troy ounce

Now, we can determine the total cost of gold needed:

Total cost of gold = 20.52 × $1654

Total cost of gold = $33,940.08.

The mass of alcohol with a density of 0.900 g/cm^3 that will have the same volume as 20 g of mercury with a density of 13.6 g/cm^3 will be 1.32 grams.

The density of a substance is given by the following formula:

Density = Mass/Volume

As 20 grams of mercury is given, we can calculate its volume using the above formula

13.6 = 20/Volume

The volume of mercury comes out to be 1.47 ml.

As the volume of mercury and alcohol is given the same in the question, we can calculate the mass of alcohol by again using the same formula

Yes his graph is accurate.

Average kinetic energy- The kinetic energy of each particle in a sample of matter varies with temperature. Instead, a wide range of kinetic energies are visible in the particles. The majority of the particle's kinetic energies fall somewhere in the middle of the range. However, a few particles have kinetic energies that are significantly lower or greater than the norm.

The average kinetic energy of a sample of matter reduces as it continues to cool. One would anticipate that the particles will eventually come to a complete stop. The temperature at which particles should theoretically stop moving is absolute zero. Temperatures on the order of 1 x 10∧ -10 K have been reached in the lab, but absolute zero has never been. Since the Kelvin temperature scale is based on molecular motion, absolute zero is often referred to as 0K. The average kinetic energy of a substance's particles directly relates to the substance's Kelvin temperature. For instance, the average kinetic energy of the particles in a sample of hydrogen gas at 200K is twice that of the particles in the same sample at 100K.

Relation between Average kinetic energy and temperature-

according to the following reaction, how many moles of silver chloride will be formed upon the complete reaction of 25.5 grams of silver nitrate with excess copper(ii) chloride?

Answers

Upon the complete reaction of 25.5 grams of silver nitrate with excess copper(ii) chloride, 0.075 moles of silver chloride will be formed.

When silver nitrate reacts with copper(II) chloride, silver chloride and copper(II) nitrate are produced. The balanced equation for this reaction is:

[tex]2AgNO_{3(aq)} +CuCl_{2(s)}[/tex] ⇒ [tex]2AgCl_{(s)} +Cu(NO_{3})x_{2(aq)}[/tex]

Using the formula to find the molar mass M = m / n, get the number of moles of silver nitrate when its mass is 25.5 grams.

M = m / n

where M = molar mass

m = mass of a substance

n = number of moles of the substance

M = m / n

169.87 g/mol = 25.5 grams / n mol

n = 0.1501147937 mol

From the balanced equation of the reaction, 2 moles of silver nitrate reacted with 1 mole of copper(ii) chloride will produce 2 moles of silver chloride and 1 mole copper(II) nitrate.

If 25.5 grams of silver nitrate is equal to 0.1501147937 mol, and for every 2 moles of it will produce 1 mole of silver chloride, then the reaction will produce 0.075 mol silver chloride.

Light with a specific wavelength has the following energy:

c = speed of light = 3*10⁸ m/s

We are given bond energy of one mole i–i , but we are required to dissociate one molecule of bromine monochloride bond.

Bond energy of one mole i–i = 153kJ/mol ( 1 mol = 6.022*10²³ )

Bond energy of one molecule of i–i = 153/6.022*10²³ kJ/molecule (1kJ = 1000J)
