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.

Suppose that H2SO4 was used in the reaction instead of HCl. How many moles of NaOH would neutralize 1 mole of H2SO4?
arlik [135]

Answer: Hence, 2 moles of NaOH would neutralize 1 mole of H_2SO_4

Explanation:

HCl+NaOH\rightarrow NaCl+H_2O

One mole of hydrochloric acid neutralizes one mole of sodium hydroxide to give one mole of sodium chloride and one mole of water

When sulfuric acid is used in the place of HCl , 1 mole of sulfuric acid will neutralizes the 2 mole of sodium hydroxide and gives one mole of sodium sulfate and 2 moles of water. As we can see from the reaction:

H_2SO_4+2NaOH\rightarrow Na_2SO_4+2H_2O

Hence, 2 moles of NaOH would neutralize 1 mole of H_2SO_4
