Answer:

Thomson's results showed that atoms contain smaller particles, so Dalton's theory had to be modified. Rutherford's results showed that most of an atom is empty space and that the mass is concentrated in the center of the atom.

Explanation:

Semenov [28]

Boyle's law states describes the relationship between volume and pressure for a given mass of gas and it aided our understanding of breathing.

Boyle's law states that, the volume of a given mass of gas is inversely related to its pressure at as long as the temperature is constant .

This means that, as the volume of a given mass of gas increases, its pressure decreases.

As the lungs expand during breathing, the volume of air in them increases as the pressure of air inside the lungs decreases.

We kept adding pbi2 into water until no more will dissolve. what is the concentration of lead (ii) iodide in the solution
blsea [12.9K]

PbI(ii) ionization in the solution of PBI(ii) into water is:

<span>PbI</span>₂(solution) <==> Pb₂⁺ + 2I⁻

If the conc. of PbI(ii) in the sol. is xM then the conc. of Lead(ii) will be x M and conc. of iodide will be 2 x M.

Therefore,

<span>Ksp=<span>[Pb</span></span>²⁺][I-]²

Plugging the values:

1.4×10⁻⁸ = x ⋅ (2x)²

1.4×10⁻⁸ = 4x³

x³ = {1.4×10⁻⁸}÷4

x³ = 0.35 x 10⁻⁸

or 

x³ = 3.5 x 10⁻⁹

x = 1.51 x 10⁻³

Hence,

Concentration of iodide ions in the solution:

2x = 3.02 x 10⁻³

Two posssible lewis structures for the molecule ch2s are given. determine the formal charge on each atom in both structures
jok3333 [9.3K]

The formal charge on each atom can be known by counting up the number of valence electrons that is present on each atom.

<h3>What is Lewis structure?</h3>

The term Lewis structure is the representation of a compound using its symbols and showing the valence electrons as dots. This question is incomplete as the Lewis structures were not shown.

If it is shown, we can know the formal charge on each atom by counting up the number of valence electrons that is present on each atom.
