Identify the state(s) of matter that each property describes.
DIA [1.3K]

Answer:

1) takes the shape of its container ( liquid and gas).

2) fills all available space (gas)

3) maintains its shape ( solid)

4) can be poured ( liquid)

5) is compressible ( gas)

6) has a fixed volume ( liquid and solid)

Explanation:

Matter is simply defined as anything that has weight and occupies space. It exists in three states, namely: solid, liquid and gaseous states.

The properties of different states of matter includes:

SOLID STATE

--> It has a definite shape: The shape of a solid is fixed; it does not depend on the shape of other materials.

--> It has a definite volume: it occupies its own shape due to the force of cohesion among its molecules.

--> It is tightly packed: The molecular movements of particles are negligible.

LIQUID STATE

--> liquid has a defined volume.

--> it has no definite shape: There is no specific shape of a liquid. It occupies any available space. It's shape depends on the shape of the container into which it is poured.

GASEOUS STATE

--> it has no fixed shape: Due to the distance in the molecules of gas, the gaseous state has no shape. It occupies the shape of its container.

--> It has no fixed volume: it occupies the shape of any container that is closed.

--> It is highly compressible: The particles of gas are far off from one another and there is room for collision.

Write three sentences that provide evidence supporting your claim about how the illustration and student observations support th
Ksenya-84 [330]

Answer:

The cell theory claims these three components:

1. cell is the smallest functional unit of life: It can be observed under the microscope that cells have various type of molecules and organelles present and have adifferent functional role in the cell which explains that the cell is the smallest unit of life as its molecules or organelles can not carry the life process on their own.

2. All organisms are made up of cells: From bacteria and archaea to human and other life forms are made up of a single cell or organization of cells in a specific pattern it also can be observed by the microscopic of blood or other tissue or cell of an organism.

3. Arise from pre-existing cell: The cells are can be studied under a microscope during cell division where we can observe that new cells come from the pre existing cell by the cell division.

How many grams of carbon dioxide are created from the complete combustion of 21.3 L of butane at STP?
Bond [772]

Answer:

165.5 g of CO2

Explanation:

We must first put down the balanced reaction equation:

C4H10(g) + 13/2 O2(g) ------> 4CO2(g) + 5H2O(g)

From the reaction equation, one mole of butane occupies 22.4 L hence we can establish the stoichiometry of the reaction thus:

22.4 L of butane created 174 g of CO2

Therefore 21.3 L of butane will create 21.3 × 174/22.4 = 165.5 g of CO2
