Answer:

3. Inverse 1. Direct

Explanation:

P- pressure

V - volume

T - temperature

P1*V1 / T1 = P2*V2 / T2 ...... (1)

That's the general gas law with the combined ideas of charles, boyle & lussac.

Whenever you are restricted as "constant" temperature, volume, or pressure...cancel them off of your equation.

in this case 3. is indirectly telling us to cancel the temperature (T).

so we'll be left w P1*V1 = P2*V2

now notice that any relation ship that is multiplied like the one above consists of inversely related quantities. & so we conclude that-

P & V are inversely proportional or have an inverse relationship.

similarly in 1. we'll cancel p off of the general formula (1)

to be left with V1/T1 = V2/T2

also note that quantities involved in division are directly related to each other & hence the answer.

Which of the following statements is INCORRECT? A. It is not possible to know the exact location of an electron and its exact en
olga nikolaevna [1]

Answer:

D. The behavior of an atom's electrons can be described by circular orbits around a nucleus.

Explanation:

<em>Which of the following statements is INCORRECT? </em>

<em>A. It is not possible to know the exact location of an electron and its exact energy simultaneously.</em> CORRECT. This is known as the Heisenberg's uncertainty principle.

<em>B. The energies of an hydrogen atom's electrons are quantized.</em> CORRECT. According to the modern atomic model, the energy levels are quantized, that is, they have a discrete amount of energy.

<em>C. The wave mechanical model correctly predicts all the energy states and the orbitals available to an electron in an hydrogen atom.</em> CORRECT. The characteristics of the energy levels are explained by Schrödinger's wave equation.

<em>D. The behavior of an atom's electrons can be described by circular orbits around a nucleus.</em> INCORRECT. This was postulated by Bohr's atomic model but it is now considered to be incorrect.

<em>E. Electrons have both wave and particle properties.</em> CORRECT. This is what De Broglie called wave-particle duality.

What would occur to cause an atom to be an ion?
kupik [55]

Answer:Some atoms become more stable by gaining or losing an entire electron (or several electrons). When they do so, atoms form ions, or charged particles. Electron gain or loss can give an atom a filled outermost electron shell and make it energetically more stable.

What is the mass of 24.6 cm3 of gasoline (density 0.680 g/cm3)?
Nata [24]

Answer:

density =  \frac{mass}{volume}  \\  \: mass = density \times volume \\ mass = 0.680 \frac{g}{ {cm}^{3} }  \times 24.9 {cm}^{3} \\  = 16.728g
