How many moles of chlorine are in 300 liters of chlorine

Answers

Answer:

13.39 mol ≅ 13.4 mol.

Explanation:

It is known that 1.0 mole of any gas occupies 22.4 L at STP conditions.

Using cross multiplication:

1.0 mole of Cl₂ occupies → 22.4 L.

??? mole of Cl₂ occupies → 300.0 L.

∴ The no. of moles of Cl₂ are in 300 liters = (1.0 mol)(300.0 L)/(22.4 L) = 13.39 mol ≅ 13.4 mol.

_____ is a gel-like substance enclosed by the cell membrane that contains the cell's organelles. A) chloroplast B) cytoplasm C) nucleus D) protein

Answers

Answer: The correct answer for the blank is-

B) cytoplasm.

Cytoplasm is the fluid filled compartment ( a thick, gel like substance) within the cell of a living organism that is mainly composed of water, salts, and proteins. It is surrounded by the cell membrane ( plasma membrane) and contains all the parts of cell ( such as in eukaryotic cell, it contains all the cell organelles except nucleus). It is the site for all the essential cellular processes.

Thus, option B) is the right answer.

Answer: Option (B) is the correct answer.

Explanation:

In a living organism, the cell which is mostly composed of water, salts and proteins is known as cytoplasm.

It is thick and gel like in nature which has fluid filled compartment.

A chloroplast is an organelle found in the cells of plants and eukaryotic algae which are responsible for the conduction of photosynthesis.

Nucleus is an organelle present in eukaryotic cells. It contains hereditary information of a cell and helps in controlling the growth and reproduction of cells.

Polymers of amino acids are known as proteins. Each protein has some specific functions.

Thus, we can conclude that out of the given options cytoplasm is a gel-like substance enclosed by the cell membrane that contains the cell's organelles.

In a model of Earth's layers that is determined by physical properties, how might the atmosphere be classified? Would it be part of the lithosphere or a seperate layer?

Answers

Generally, the Earth is divided into spheres which include the "lithosphere" (land), "hydrosphere" (water), "biosphere" (living things), and "atmosphere" (air). The earth is divided into three layers based on chemical composition and these are the core, mantle and crust. In addition, the earth is also divided into physical properties which include lithosphere, athenosphere, mesosphere, outer core and inner core. Based on the given details, we can conclude that the atmosphere cannot be part of the lithosphere but instead, it is classified in a separate layer. The lithosphere only consists the outermost, rigid part of the Earth, which are the crust and the mantle. Hope this answer helps.

Is it possible to make CD without plastic? why or why not?

Answers

No, it is not possible to make CD by other material except plastic.

The full form of CD is compact disks. It is simple disk of plastic

Why CD made up of plastics ?

The CD is made up of plastic mainly with polycarbonate plastic (PC) .

The PC is stronger and mechanically more stable. CD must be stronger enough to resist any mechanical damage like scratching.
The PC are quite temperature and and impact resistance and highly transparent.
It provides the disc depth necessary to maintain laser focus on the metal and data layer.
The surface of the CD is reflective because it is coated with thin layer of aluminium and sometimes gold .
