Answer:

The correct answer is 3.6 L

Explanation:

According to the gases Boyle's law, the relation between the volume and  the pressure of a gas at constant temperature is given by the following mathematical expression:

Pi x Vi = Pf x Vf

Where Pi and Vi are the <u>initial </u>pressure and volume of the gas whereas Pf and Vf are the <u>final</u> pressure and volume, respectively.

In this problem we have:

Vi = 18.0 L

Pi= 902 Torr

Pf= 4510 Torr

The final volume (Vf) will be:

Vf = (Pi x Vi)/Pf = (902 Torr x 18.0 L)/4510 Torr= 3.6 L

From the result, we can see that if the pressure increases, the volume of the gas decreases.

Vladimir [108]

Answer:

Thomson made the following conclusions: The cathode ray is composed of negatively-charged particles. The particles must exist as part of the atom, since the mass of each particle is only ∼ 20001​start fraction, 1, divided by, 2000, end fraction the mass of a hydrogen atom.

Which rule for assigning oxidation numbers is correct?
LenKa [72]
Hydrogen is usually –1. This is INCORRECT. The oxidation number for H is +1.
Oxygen is usually –2. This is CORRECT.
A pure group 1 element is +1. This is INCORRECT. It does not follow. This will depend on the other elements and the overall charge.
A monatomic ion is 0. This is INCORRECT. Diatomic ion is 0.

TiliK225 [7]
One kilogram is equal to one thousand grams. Further, one gram is equal to 1000 mg. The conversion is as shown below,
                    (6.285 x 10³ mg) x (1 g / 1000 mg) x (1 kg / 1000 g)
The numerical value of the operation above is 0.006285 kg.

The radius of an atom is closest in size to a
tigry1 [53]

Answer:

The size of an isolated atom can't be measured because we can't determine the location of the electrons that surround the nucleus. We can estimate the size of an atom, however, by assuming that the radius of an atom is half the distance between adjacent atoms in a solid. This technique is best suited to elements that are metals, which form solids composed of extended planes of atoms of that element. The results of these measurements are therefore often known as metallic radii.
