Answer:

The mass of 106.4L of F₂ is 180.48 g

Explanation:

To find the mass of 106.4L of gas you must know the density of it.

Density = mass / volume

Density F₂ = 1,696 kg/m³

Let's make some conversion of units

1m³ = 1000 dm³

1 dm³ = 1L

1.696 kg = 1696 g

So now the rule of three to convert the density

In 1000 dm³ there are 1696 g of mass

In 1 dm³ there are 1.696 g

Density F₂ = 1.696 g/L

Density F₂ = F₂ mass / F₂ volume

1.696 g/L = F₂ mass / 106.4 L

1.696 g/L . 106.4L = F₂ mass

What is the concentration of a solution?

Anon25 [30]

Concentration Definition. In chemistry, concentration refers to the amount of a substance per defined space. Another definition is that concentration is the ratio of solute in a solution to either solvent or total solution. Concentration usually is expressed in terms of mass per unit volume.

Part A Add single electrons and/or electron pairs as needed to complete the electron-dot symbol for astatine, At. To return the

mezya [45]

Answer:

7 valence electrons

Explanation:

Astatine has the atomic number 85. Thus, its electron configuration is:

[Xe] 4f¹⁴ 5d¹⁰ 6s² 6p⁵

As we can see, in the last level (6) it has 2 + 5 = 7 electrons, that is, astatine has 7 electrons in its valence shell. In the Lewis dot structure (attached) we write 3 pairs of electrons and 1 unpaired electron around the symbol of At.

In the nuclear transmutation represented by 168o(p, \alpha) 137n, the emitted particle is ________.

Alecsey [184]

Answer is: <span>the emitted particle is an alpha particle.
</span>

Nuclear reaction: ¹⁶O + p⁺ → ¹³N + α (alpha particle).<span>
Alpha decay is radioactive decay in which an atomic nucleus emits an alpha particle (helium nucleus) and transforms into an atom with an atomic number that is reduced by two and mass number that is reduced by four.
When oxygen-16 gain one proton, atomic mass is 17, but when lose alpha particle atomic mass reduces by four to 13.</span>
