Why? Because liters - kilolitres:  ÷ 1000

Two or more than two atoms with different physical or chemical properties can not combine together to form an element.  Energy is the only factor that  determines the color of light of fireworks.

Element generally consist of atoms or we can atoms combine to form element. Atoms of an element is always same, means all the properties of all atoms of one type of element is same.

Fireworks has many different types of element. When any element is given an energy. Then the process of excitation of electrons takes place from its outermost shells. Every element absorb characteristic wavelength of energy and releases light to the corresponding wavelength.

Therefore, energy is the only factor that  determines the color of light of fireworks.

Direct coupling

Explanation:

Direct coupling is sensitive to changes that occurs in temperature. It is electrical energy transfer using physical contact through a medium that is conductive.

It is useful in the interconnection of 2 circuits. This kind of coupling method can be done by a wire, a resistor or through mettalic bonding.

Answer:

They are more spread out.

Explanation:

The atoms and molecules in gases are much more spread out than in solids or liquids. They vibrate and move freely at high speeds. A gas will fill any container, but if the container is not sealed, the gas will escape. Gas can be compressed much more easily than a liquid or solid.

Answer:

Explanation:

Explanation:

Gas – In a gas, particles are in continual straight-line motion. The kinetic energy of the molecule is greater than the attractive force between them, thus they are much farther apart and move freely of each other. In most cases, there are essentially no attractive forces between particles

Answer:

[tex]m=4.21g[/tex]

Explanation:

Hello,

In this case, by using the ideal gas equation:

[tex]PV=nRT[/tex]

We can compute the mass of neon gas at the given conditions by firstly computing the moles and also considering the temperature in kelvins (298K):

[tex]n=\frac{PV}{RT}=\frac{1.02atm*5.00L}{0.082\frac{atm*L}{mol*K}*298K}\\ \\n=0.209mol[/tex]

Finally, by using the atomic mass of neon gas (20.18g/mol) we compute the required mass to fill the 5.00-L container:

[tex]m=0.209mol*\frac{20.18g}{1mol}\\ \\m=4.21g[/tex]

Best regards.

The mass of neon gas will be "4.21 g".

Given:

By using Ideal Gas Equation,

⇒ [tex]PV = nRT[/tex]

or,

⇒    [tex]n = \frac{PV}{RT}[/tex]

By substituting the values,

         [tex]= \frac{1.02\times 5.00}{0.082\times 298}[/tex]

         [tex]= 0.209 \ mol[/tex]

hence,

The Mass will be:

= [tex]0.209\times \frac{20.18}{1}[/tex]

= [tex]4.21 \ g[/tex]

Thus the above answer is right.

halving the volume of a gas

Explanation:

Entropy refers to the degree of disorderliness of a system. The greater the volume of a gas, the greater its entropy. The entropy of a system is directly proportional to its volume.

Hence a decrease in the volume of a gas leads to a decrease in its entropy. Ultimately, if the volume of a given mass of gas is halved, its entropy decreases according.

The correct answer is 1030 km

Explanation:

The distance a body such as a submarine travels depends on two main variables the time of the movement and the speed. Indeed, to calculate the distance it is possible to use the formula d = s x t. The process to calculate the distance of the submarine journey is shown below:

Distance in the first part of the journey:

It is known during the first part of the journey the submarine traveled 5 hours at a speed of 106 km/h

Distance = speed × time

D = 106 km/h × 5 h

D = 530 km

Distance in the second part of the journey:

During the remaining 4 hours (the first part took 5 hours and the total time traveled were 9 hours) the speed was 125km/h. Now, let's calculate the distance covered during this part of the journey

Distance = speed × time

D= 125 km/h × 4 h

D= 500 km

Total distance:

Finally, add both distances to know the total distance

530 km + 500 km = 1030 km

Answer:

Concentration of H3O⁺  [H3O⁺] = 0.864 M

Explanation:

Given that:

The mass concentration of MO = 43 g/L

The volume of MO = 7.9 mL = 7.9 × 10⁻³ L

Recall that

The mass number of MO = Mass concentration of MO × Volume of MO

The mass number of MO = (43 g/L) * (7.9 × 10⁻³ L)

The mass number of MO =  0.3397 g

number of  moles of MO = (mass number of MO) / (molar mass of MO)

number of  moles of MO = (0.3397 g) / (327.33 g/mol)

moles of MO = 0.00104 mol

The total volume = 7.9 mL + 3.13 mL + 5.49 mL + 3.43 mL

The total volume = 19.95 mL = 19.95 × 10⁻³ L

Concentration of MO [MO} =(number of moles of MO) / (total volume)

[MO] = 0.00104 mol  /  19.95 × 10⁻³ L

[MO] = 5.2130 × 10⁻⁸ M

the number of moles of H3O⁺ = molarity of HCl in the solution × the volume of HCl in solution

the number of moles of H3O⁺ = [(2.0 M) * (3.13 mL)] + [(2.0 M) * (5.49 mL)]

the number of moles of H3O⁺ = 17.24 mmol

Concentration of H3O⁺  [H3O⁺] = (the number of moles of H3O⁺) / (total volume)

Concentration of H3O⁺  [H3O⁺] = (17.24 mmol) / (19.95 mL)

Concentration of H3O⁺  [H3O⁺] = 0.864 M

The Concentration of H3O⁺  [H3O⁺] is 0.864 M

But before that following calculations should be needed.

The mass number of MO = Mass concentration of MO × Volume of MO

= (43 g/L) * (7.9 × 10⁻³ L)

=  0.3397 g

Now

number of  moles of MO = (mass number of MO) / (molar mass of MO)

= (0.3397 g) / (327.33 g/mol)

= 0.00104 mol

Now

The total volume = 7.9 mL + 3.13 mL + 5.49 mL + 3.43 mL

= 19.95 mL

= 19.95 × 10⁻³ L

Now

Concentration of MO [MO} =(number of moles of MO) / (total volume)

= 0.00104 mol  /  19.95 × 10⁻³ L

5.2130 × 10⁻⁸ M

Now

the number of moles of H3O⁺ = molarity of HCl in the solution × the volume of HCl in solution

= [(2.0 M) * (3.13 mL)] + [(2.0 M) * (5.49 mL)]

= 17.24 mmol

Now

Concentration of H3O⁺  [H3O⁺] = (the number of moles of H3O⁺) / (total volume)

= (17.24 mmol) / (19.95 mL)

= 0.864 M

Hence, The Concentration of H3O⁺  [H3O⁺] is 0.864 M

Step 1: Given data

Step 2: Calculate the mass of salt

The mass of the sample is equal to the sum of the masses of the components.

m(sample) = m(iron) + m(sand) + m(salt)

m(salt) = m(sample) - m(iron) - m(sand)

m(salt) = 2.875 g - 0.660 g - 1.161 g

m(salt) = 1.054 g

Step 3: Calculate the percent of salt in the sample

We will use the following expression.

%(salt) = m(salt) / m(sample) × 100%

%(salt) = 1.054 g / 2.875 g × 100% = 36.66%

The percent of salt in the original sample containing only iron, sand, and salt is 36.66%.

Salt is a mineral made up of primarily sodium chloride.

Seawater contains a vast amount of salt.

Given,

The total mass of the sample is 2.875 g

Mass of iron is  0.660 g

Mass of sand is 1.161 g

Step 1: To find the mass of salt

The total mass of the sample = the sum of the masses of the compounds

m(sample) = m(iron) + m(sand) + m(salt)

2.875 g =  0.660 g + 1.161 g + m(salt)

m(salt) = 2.875 g - 0.660 g - 1.161 g

m(salt) = 1.054 g

Step 2: Calculate the percent of salt in the sample

[tex]\%(salt) = \dfrac{m(salt) }{m(sample)} \times 100\%\\\\\\\%(salt) = \dfrac{1.054 g }{2.875 g} \times 100\% = 36.66\%[/tex]

Thus, the percentage of salt in the sample is 36.66%.

% mass of Ethylene glycol =(  mass of ethylene glycol/ mass of solution )x100%

                        =  62.1 g/ (62.1  +  250 )   x 100%

                       = 24.24%

Mass percentage is a term that represents the concentration, basically mass by mass percentage. It tells about the percentage of a component in a whole component. Therefore, the mass % of ethylene glycol is  24.24%.

Mass percentage represents the the percentage of each element that is making a particular compound. Mass percentage does not have any unit as numerator and denominator contains the same unit.

Mathematically,

Percentage of mass = (component’s mass ÷ total mass) x 100%

% mass of Ethylene glycol =(  mass of ethylene glycol/ mass of solution)x100%

% mass of Ethylene glycol =  62.1 g/ (62.1  +  250 )   x 100

                                             = 24.24%
