Answer:

V₂ = 28 mL

Explanation:

Given data:

Initial temperature = 303 K

Initial volume = 30.0 mL

Final temperature = 283 K

Final volume = ?

Solution:

The given problem will be solve through the Charles Law.

According to this law, The volume of given amount of a gas is directly proportional to its temperature at constant number of moles and pressure.

Mathematical expression:

V₁/T₁ = V₂/T₂

V₁ = Initial volume

T₁ = Initial temperature

V₂ = Final volume  

T₂ = Final temperature

Now we will put the values in formula.

V₁/T₁ = V₂/T₂

V₂ = V₁T₂/T₁  

V₂ = 30.0 mL × 283 K /303 K

V₂ = 8490 mL.K / 303 K

V₂ = 28 mL

C. how many particles are in the substance

Answer:

Explanation:

Mass of Copper(I) chromate( CuCrO₄) = 19.75 g

The mole is the number of particles contained in a substance

1 mol = 6.02.10²³

Moles can also be determined from the amount of substance mass and its molar mass

[tex]\tt \large{\boxed{\bold{mol=\dfrac{m(mass)}{MW(molecular~weight)}}}[/tex]

0.11 mole of Copper(I) chromate( CuCrO₄) ⇒ MW=179.54 g/mol, so mass :

[tex]\tt mass=mol\times MW\\\\mass=0.11\times 179.54\\\\mass=19.75~g[/tex]

Answer:

Explanation:

The pressure required can be found by using the formula for Boyle's law which is

[tex]P_1V_1 = P_2V_2[/tex]

Since we are finding the required pressure

[tex]P_2 = \frac{P_1V_1}{V_2} \\[/tex]

From the question we have

Explanation:

The number of moles of aluminum for 1.204 x 0²³ atoms of aluminum is 0.2 moles. Hence, The correct answer is Option (A)

Mole is defined as the amount of the substance containing the same number of discrete entities (atoms, molecules, ions, etc) as there are atoms in a sample of pure 12C weighing exactly 12g.

The number of particles present in one mole of any substance = Avogadro Number = 6.023 x 10²³.

Formula to calculate Mole when number of particles is given ;

n = given number /  6.023 x 10²³

n = 1.204 x 10²³ / 6.023 x 10²³

n = 0.2 moles

Therefore, The number of moles of aluminum for 1.204 x 0²³ atoms of aluminum is 0.2 moles. Hence, The correct answer is Option (A)

Answer:

Average atomic mass  = 79.9 amu.

Explanation:

Given data:

Average atomic mass of Bromine = ?

Atomic mass of 1st isotope = 78.92 amu

Relative abundance of 1st isotope = 50.69%

Atomic mass of 2nd isotope = 80.92 amu

Relative abundance of 1st isotope = 49.31%

Solution:

Average atomic mass = (abundance of 1st isotope × its atomic mass) +(abundance of 2nd isotope × its atomic mass)  / 100

Average atomic mass  = (50.69×78.92)+(80.92×49.31) /100

Average atomic mass =  4000.45 + 3990.16 / 100

Average atomic mass  = 7990.61 / 100

Average atomic mass  = 79.9 amu.

Answer:

Some notable differences between a main sequence star and a red giant are its sizes and color. Red Giants tend to typically be, well, red. The output of a red giant is so much greater than that of a main sequence. A red giant is the last stage of a main sequence star's life. Another difference is what occurs inside the star. Main sequence stars fuse hydrogen together in order to keep gravity from imploding the star, while red giants run short of hydrogen and fuses helium.

D dark colors absorb the sun more cause the wants to make everything bright I hope I helped :)

The statement " Darker colors absorb more energy from electromagnetic waves than lighter colors do." is correct.

When an electric field collides with a magnetic field, electromagnetic waves are created. As a result, they're called electromagnetic waves.

Light, often known as visible light, is electromagnetic radiation that falls within the region of electromagnetic wave or spectrum that the human eye can perceive.

White is a mixture of all seven colors found in the white light spectrum, including Violet, Indigo, Blue, Green, Yellow, Orange, and Red. This visible spectrum has a wavelength of 400 to 700 nanometers. When an object appears to be a particular color, such as red, it signifies that it is projecting the wavelength of red light  (620 to 750 nanometers) while absorbing all other wavelengths. Furthermore, because  light is a kind of energy, the more light a thing consumes, the more heat it consumes.
