A brief explanation to this question: "Why are neon signs/fireworks different colors? Please help me. Do not look up internet

Answers

Answer:

when lit, the atoms of different chemical compounds inside the firework absorb energy, when the electrons fall back to lower energy levels, they give off colored light. Depending upon the chemical used, different colors are produced. neon lights or signs are glass tubes filled with neon gas. When the light is plugged in, the electrical energy causes the electrons of neon to jump to higher energy levels, when they go to lower levels, colored light is given off. The neat thing is that the neon never gets used up. The only thing that gets used up is the electricity. The electrons don't get destroyed and can be used over and over again jumping levels. Neon glows with an orange light, but you know that neon signs can be lots of different colors. The variations come when different gases other than neon are used such as argon, or krypton or when the tube is painted so that with the light produced it produces a certain color.

Explanation:

After being excited by high levels of electrical energy (as in neon signs) or heat energy, various elements and molecules will emit their own specific colors of light.

What are basis behind fireworks?

Metals burn in a variety of colors. When a copper compound is lit, for example, the flame is blue-green.

Calcium burns red, while potassium burns purple. Metals are combined to produce various colors in fireworks.

The appearance of each firework is determined by the type of stars it contains, as well as the size and quantity of these pellets.

Some stars contain metal salts, which produce brilliant colors, while others contain a variety of chemical compounds that produce dazzling light effects such as strobing, sparkling, and others.

Various elements and molecules will emit their own specific colors of light after being excited by high levels of electrical energy (as in neon signs) or heat energy (as in the fireworks).

Thus, the neon signs or fireworks provide different colors.

How much heat is required to melt 42.0 grams of water at 0*C?
Hurry...

Answers

Answer:

Heat required to melt 42 g if ice is 13,860 J

Explanation:

The amount of heat required to melt  grams of water at 0°C is given as follows;

The mass of the ice (water), m = 42 g

The latent heat of fusion of ice Δ[tex]H_f[/tex]= 330 J/g

Therefore, heat required to melt 42 grams is given as follows;

Heat required to melt ice = Mass of the ice, m × The specific latent heat of fusion of the ice, Δ[tex]H_f[/tex]

Heat required to melt 42 g if ice = m × Δ[tex]H_f[/tex] = 42 g × 330 J/g = 13,860 J

Heat required to melt 42 g if ice = 13,860 J.

Heat can be calculated using the formula:

When copper is bombarded with high-energy electrons, X rays are emitted. Calculate the energy (in joules) associated with the photons if the wavelength of the X rays is 0.154 nm.

Answers

Answer:

E = 12.92 × 10^(-16) J

Explanation:

Formula for energy is;

E = hc/λ

Where;

h is Planck's constant = 6.63 x 10^(-34) J.s

c is speed of light = 3 × 10^(8) m/s

λ is wavelength = 0.154 nm = 0.154 × 10^(-9) m

E = (6.63 x 10^(-34) × 3 × 10^(8))/(0.154 × 10^(-9))

E = 12.92 × 10^(-16) J

The energy associated with the photons of X rays with a wavelength of 0.154 nm is 1.29 × 10⁻¹⁵ J.

When copper is bombarded with high-energy electrons, X rays, with a wavelength of 0.154 nm (λ) are emitted.

We can calculate the energy (E) associated with the photons of these X rays using the Planck-Einstein relation.

[tex]E = \frac{h \times c }{\lambda } = \frac{(6.63 \times 10^{-34}J.s ) \times (3.00 \times 10^{8}m/s ) }{0.154 \times 10^{-9} m } ]= 1.29 \times 10^{-15} J[/tex]

Determine how you would prepare 220 mL of a 0.500 M potassium hydroxide solution starting with: a) solid potassium hydroxide b) a 1.25 M potassium hydroxide solution​

Answers

Answer:

a) 6.17 g of solid KOH

b) 88.0 mL of a 1.25 M potassium hydroxide solution​

Explanation:

a) We have to determine the mass of solid potassium hydroxide that has to be weighed to prepare 220 mL of a 0.500 M potassium hydroxide solution. We will also require the molar mass of potassium hydroxide, KOH, 56.11 g/mol.

0.220 L × (0.500 mol/L) × (56.11 g/mol) = 6.17 g

b) We will use the dilution rule to determine the volume of the 1.25 M potassium hydroxide solution​ to be measured.

C₁ × V₁ = C₂ × V₂

V₁ = C₂ × V₂ / C₁

V₁ = 0.500 M × 220 mL / 1.25 M = 88.0 mL
