Scrat [10]2 years ago
8 0

Answer:

Electrons at the outermost energy level of an atom are called valence electrons. They determine many of the properties of an element. That's because these electrons are involved in chemical reactions with other atoms. Shared electrons bind atoms together to form chemical compounds.

What does compression do?
erma4kov [3.2K]

Explanation:

Compressors and limiters are used to reduce dynamic range — the span between the softest and loudest sounds. Using compression can make your tracks sound more polished by controlling maximum levels and maintaining higher average loudness.

108/49 In ? 108/48 Cd + ? In the equation above, what particle or type of radiation needs to be included on the right hand side
Oksanka [162]

Answer: b) positron

Explanation:

The antiparticle or the antimatter counterpart of the electron is called positron.

The positron has an electric charge of +1 e and same mass as an electron. When a positron collides with an electron, annihilation takes place.

What mass of lif is contained in 18.66 g of a 20.0% by mass solution of lif in water?
aev [14]
Answer is: mass of lithium fluoride is 3,732 grams.
m(solution) = 18,66 g.
ω(solution) = 20% = 20% ÷ 100% = 0,2.
m(LiF) = ?
ω(solution) = m(LiF) ÷ m(solution).
m(LiF) = ω(solution) · m(solution).
m(LiF) = 0,2 · 18,66 g.
m(LiF) = 3,732 g.

A proton in a linear accelerator has a de Broglie wavelength of 132 pm. What is the speed of the wavelength?
kherson [118]

Answer:

The speed of wavelength is 3.0 ×10³ m/s.

Explanation:

Given data:

De Broglie wavelength = 132 pm (132×10⁻¹² m)

Speed of wavelength = ?

Solution:

Formula:

λ = h/mv

λ = wavelength

h = planck's constant

m = mass of proton

v = speed

now we will put the values in formula.

132×10⁻¹² m = 6.63 ×10⁻³⁴ j.s / 1.67 ×10⁻²⁷ kg × v

v =  6.63 ×10⁻³⁴ j.s / 1.67 ×10⁻²⁷ kg × 132×10⁻¹² m

j = kg m²/s²

v = 6.63 ×10⁻³⁴ kg m²/s / 1.67 ×10⁻²⁷ kg × 132×10⁻¹² m

v = 6.63 ×10⁻³⁴ kg m²/s / 220.44 ×10⁻³⁹ kg.m

v = 0.03×10⁵ m/s

v = 3.0 ×10³ m/s

The speed of wavelength is 3.0 ×10³ m/s.
