The simple interest is equal to $3740 on a principal of $ 22,000, deposited for 4 years at a rate of 4.25 %.

Simple interest can be based on the principal of a loan. Simple interest does not compound, a creditor only pays interest on the principal amount and a borrower never has to pay more interest on the previous interest.

Simple Interest (S.I.) can be described as the method of determining the interest amount for a principal of money at the rate of interest.

To determine simple interest, multiply the principal by the interest rate and the time.

Simple Interest = Principal ×Rate × Time

Given, the principal amount, P =$ 22000

The rate, R = 4.25%

Time, T = 4 years

The simple interest can be calculated as:

[tex]\displaystyle S.I. =\frac{P\times R\times T}{100}[/tex]

[tex]\displaystyle S.I. =\frac{22000\times 4.25\times 4}{100}[/tex]

Simple interest = $ 3740

Therefore, the simple interest is equal to $ 3740.

Answer:

Heat absorbed by water is 12540 J

Explanation:

Given data:

Mass of water = 100 g

Temperature changes = 20.0°C to 50.0°C

Heat absorbed by water = ?

Solution:

Specific heat of water is 4.18 j/g.°C

Formula:

Q = m.c. ΔT

Q = amount of heat absorbed or released

m = mass of given substance

c = specific heat capacity of substance

ΔT = change in temperature

ΔT = 50.0°C - 20.0°C

ΔT = 30.0°C

Q = m.c. ΔT

Q = 100 g. 4.18 j/g.°C. 30.0°C

Q = 12540 J

Heat absorbed by water is 12540 J.

Using the formula for heat absorption (q=mcΔT), we can calculate that the water absorbed 12,552 joules of heat when it was heated from 20.0°C to 50.0°C.

In order to determine the amount of heat absorbed by the water when being heated from 20.0°C to 50.0°C, we can use the formula q = mcΔT.

Here, 'q' is the heat absorbed, 'm' is the mass, 'c' is the specific heat capacity of water, and 'ΔT' is the change in temperature. Given the mass (m) of the water is 100.0 grams, the specific heat capacity (c) of water is 4.184 J/g°C, and the change in temperature (ΔT) is 50.0°C - 20.0°C = 30.0°C.

Substituting these values into the equation gives q = (100.0g)(4.184 J/g°C)(30.0°C) = 12,552 joules. Therefore, the water absorbed 12,552 joules of heat when it was heated from 20.0°C to 50.0°C.

To find the new volume of the nitrogen gas at a different pressure, we can use the gas law equation PV = nRT. By rearranging the equation and plugging in the given values, we can calculate the new volume.

To solve this problem, we can use the gas law equation: PV = nRT, where P is pressure, V is volume, n is the number of moles, R is the gas constant, and T is the temperature in Kelvin. Since the temperature remains constant, we can simplify the equation to PV = constant. First, we need to convert the pressure from mm Hg to atm by dividing it by 760. Then, we can use the equation to find the new volume:

P1V1 = P2V2

Plugging in the values and solving for V2:

V2 = (P1 * V1) / P2

Let's substitute the given values:
V2 = (0.971 atm * 500 ml) / (1140 mm Hg / 760 mm Hg/ atm)

After converting mL to L and performing the calculation, we get:

V2 = 0.207 L

Globular clusters are some of the oldest structures in the Milky Way, with ages suggesting the age of the universe to be at least around 11 to 13 billion years old. The Boomerang Nebula is among the youngest and coldest objects known. The study of distant galaxies and ancient globular clusters helps astronomers understand the early universe.

The oldest and farthest celestial bodies in the universe provide insight into the universe's early history. Globular clusters are among the oldest structures in our Galaxy, with the youngest being about 11 billion years old, setting a lower limit for the age of the universe. Our Milky Way, containing such ancient globular clusters, suggests it was born at least 13 billion years ago. One famous globular cluster, M13, is roughly 26,000 light-years away from us and has an estimated mass of around a million times that of the Sun. In contrast to these ancient objects, the Boomerang Nebula is a much younger planetary nebula and is currently the coldest known object in the Universe.

In order to understand the early universe, astronomers study not only globular clusters but also very distant galaxies, as they provide a view of the universe when it was very young. Observations of stars in the halo of the Milky Way, red giant stars, suggest distances of almost 1 million light-years, indicating the immense scale and diversity of structures within our galaxy.

Answer:

This is true.

Explanation:

Speed of the particles in terms of energy is described by kinetic energy. Kinetic energy is directly proportional to the square of velocity. Essentially, the greater the speed of the particles, the greater the kinetic energy.

Now, let's say our particles are in some specific container. When particles move fast, they possess high kinetic energy. The greater the kinetic energy the more of it can be transferred to the walls of a container when particles collide with them. This is transferred as another energy form, heat. Particles lose a fraction of their kinetic energy by transferring it to the container and heating it up.

Answer:

The grams of aluminum sulfide formed are ; 12.51 g

Explanation:

Using Formula,

[tex]mole = \frac{given\ mass}{Molar\ mass}[/tex]

Calculate the moles of Al and S :

Given  mass of Al = 9 g

Molar mass of Al = 27 g/ mole

[tex]mole = \frac{9}{27}[/tex]

Mole of Al = 0.33

Given  mass of S =  8 g

Molar mass of S = 32 g/mole

[tex]mole = \frac{8}{32}[/tex]

Mole of S  = 0.25

The balanced chemical equation for the reaction between aluminium and sulfur is :

[tex]2Al(s) + 3S(s)\rightarrow Al_{2}S_{3}(s)[/tex]

Here ,

2 mole of Al needs 3 moles of S

1 mole  of Al needs 3/2(= 1.5) moles of S

hence  ,

0.33 mole of Al should require

[tex]\frac{3}{2}\times 0.33[/tex] moles of S

Sulfur needed = 0.495 mole

Available S = 0.25 mole

So there is less sulfur than required , S is the limiting reagent

Amount of S decide the Amount of Al2S3 formed

3 mole of S produce 1 mole of Al2S3

1 mole of S produce 1/3 mole of Al2S3

0.25 mole will produce :

[tex]0.25\times\frac{1}{3}[/tex]

= 0.0833 moles of Al2S3

[tex]Al_{2}S_{3}[/tex] = 0.083 mole

Molar mass of

[tex]Al_{2}S_{3}[/tex] = 150.16 g/mole

[tex]mole = \frac{given\ mass}{Molar\ mass}[/tex]

[tex]given\ mass = moles\times molar\ mass[/tex]

[tex]given\ mass = 0.083\times 150.16[/tex]

Explanation:

Answer:

85 x 10³ ppm  

Explanation:

Data Given:

mass of sucrose = 17 g

mass of water = 183 g

Concentration in ppm = ?

Solution:

Formula Used

                   Concentration (ppm) = Solute / Solution x 10⁶ ............ (1)

**Note : 1 ppm = 1 mg / L

First we have to know about mass of solution

So

       Mass of solution = mass of solute + mass of solvent ................. (2)

Put values in equation 2

        Mass of solution = 17 g sucrose + 183 g water

        Mass of solution = 200 g

Now Put Values in equation 1

          Concentration (ppm) = Solute / Solution x 10⁶

          Concentration (ppm) = 17 g / 200g x 10⁶

          Concentration (ppm) = 0.085 x 10⁶

           Concentration (ppm) = 85 x 10³

Concentration  of sucrose = 85 x 10³ ppm      

The concentration of sucrose in the solution is 85,000 parts per million (ppm).

The concentration of sucrose in the given solution can be calculated using the formula:

Concentration (ppm) = mass of solute (g) / mass of solution (g) x 10^6

For this case, the mass of sucrose is 17 grams and the mass of the solution (sucrose + water) is 17 grams + 183 grams = 200 grams. Plugging in the values, we get:

Concentration (ppm) = 17 g / 200 g x 10*6 = 85,000 ppm

Therefore, the concentration of sucrose in the solution is 85,000 parts per million (ppm).

Answer:

78.9g

Explanation:

To find the mass of magnesium chloride produced, convert 20.0 g of magnesium to moles, use the reaction's stoichiometry to get the moles of magnesium chloride, and then convert back to grams. The balanced chemical equation for the reaction is Mg(s) + 2 HCl(aq) → MgCl₂(aq) + H₂(g), and the result is 78.33 grams of magnesium chloride.

To find out how many grams of magnesium chloride will be produced when 20.0 g of magnesium react with excess hydrochloric acid, we first need to consider the balanced chemical equation for the reaction:

Mg(s) + 2 HCl(aq) → MgCl₂(aq) + H₂(g)

From the balanced equation, we see that one mole of magnesium (Mg) reacts with two moles of hydrochloric acid (HCl) to produce one mole of magnesium chloride (MgCl₂) and one mole of hydrogen gas (H₂). To determine the mass of magnesium chloride produced, use the molar mass of magnesium (24.31 g/mol) to convert the mass of magnesium into moles, then use the stoichiometry of the reaction to find the corresponding moles of magnesium chloride produced.

The molar mass of magnesium chloride (MgCl₂) is 95.21 g/mol. After calculating the moles of Mg, that amount will be directly equal to the moles of MgCl₂ formed, since the ratio is 1:1. Finally, convert the moles of magnesium chloride to grams using its molar mass.

The calculation steps are as follows:

Therefore, 78.33 grams of magnesium chloride will be produced when 20.0 g of magnesium reacts with excess hydrochloric acid.
