Compare and contrast the functions of each of the following types of flasks: filter, Erlenmeyer, volumetric.

Answer:

The new gas pressure within the chamber registers at 1,093.75 mmHg

Explanation:

The Gay-Lussac Law establishes a relationship between a gas's pressure and temperature when volume remains constant. This principle asserts that gas pressure is directly tied to its temperature: as temperature increases, pressure rises, and conversely, as temperature falls, pressure also diminishes. Therefore, the Gay-Lussac law can be depicted mathematically as:

Given an initial and final state of gas, we can apply the following formula:

In this scenario:

• P1= 1560 mmHg
• T1= 445 K
• P2=?
• T2= 312 K

Calculating:

P2=1,093.75 mmHg

The new gas pressure inside the chamber is 1,093.75 mmHg

Answer;

As and Sr ------- [Kr]

Be ------------- [He]

O and Mg ------- [Ne]

S and Ca ------- [Ar]

Explanation

• The Be+ ion has 2 electrons, matching He. The Mg2+ and O2− ions possess 10 electrons each, like Ne.
• S2− and Ca2+ ions each have 18 electrons, the same as Ar. The As3− and Sr+ ions hold 36 electrons, paralleling Kr.
• Elements gain or lose electrons to reach a stable electron configuration akin to that of noble gases.
• When atoms lose electrons, they form positive ions (cations), and when they gain electrons, they form negative ions (anions).

Answer: The solid metal has a density of 22.5176 g/cm

Explanation:

Based on the information provided;

mass of the solid metal is 255 g

the weight of the cylinder along with its contents decreased by 101 g

it is also stated that the density of mercury is 13.6 g/cm³

The volume occupied by the solid metal is equal to the volume of mercury that was missing during the initial measurement

let's denote the volume as Vcm³

The mass of mercury that was missing during the first measurement can be calculated as density multiplied by volume

= 13.6 g/cm³ × Vcm³ = 13.6V g

Given the cylinder and its contents lost 101 g in weight,

the difference in mass between the solid and the mercury must equal 101 g

therefore,

255 - 13.6V g = 101g

13.6V g = 255 g - 101 g

13.6V = 154

V = 154 / 13.6

V = 11.3245 cm³

The density of the solid metal can then be found by;

⇒ mass / volume

= 255 / 11.3245

= 22.5176 g/cm

Thus, the density of the solid metal equals 22.5176 g/cm

Could you please inform me once you have any updates? I'm interested as it relates to a chemistry problem in my assignment.:)
