An ideal gas is kept in a 10​-liter ​[L] container at a pressure of 2.5 atmospheres​ [atm] and a temperature of 310 kelvin​ [K].
Hatshy [7]

Answer:

5 L.

Explanation:

From the question given above, the following data were obtained:

Initial volume (V1) = 10 L

Initial pressure (P1) = 2.5 atm

Final pressure (P2) = 5 atm

Final volume (V2) =.?

Since the temperature is constant, we shall apply the Boyle's law equation to determine the new volume of the gas. This can be obtained as follow:

P1V1 = P2V2

2.5 × 10 = 5 × V2

25 = 5 × V2

Divide both side by 5

V2 =25/5

V2 = 5 L

Thus, the new volume of the gas is 5 L

From the absorption spectra of a gas, we can see the  amount of thermal energy the gas contains (option D).

<h3>What is the absorption spectra?</h3>

The absorption spectra shows us the energy that is taken in by a gas. We know that when a gas is heated, it absorbs energy which shows up in its absorption spectra.

Thus, from the absorption spectra of a gas, we can see the  amount of thermal energy the gas contains.

Identify the single displacement reaction.
pishuonlain [190]

Answer : The correct option is, (D)

Explanation :

Option A reaction : C_4H_{12}+7O_2\rightarrow 6H_2O+4CO_2

It is a combustion reaction. A reaction in which a hydrocarbon react with the oxygen to give product as carbon dioxide and water.

Option B reaction : 2H_2+O_2\rightarrow 2H_2O

It is a combination reaction. A reaction in which the two or more reactants react to give a product.

Option C reaction : Al_2S_3\rightarrow 2Al+3S

It is a decomposition reaction. A reaction in which a reactant decomposes to form two or more products.

Option D reaction : Cl_2+2KBr\rightarrow 2KCl+Br_2

It is a single displacement reaction. It is a reaction in which the more reactive element displace the less reactive element.  In this reaction, most reactive element chlorine displaces the less reactive element bromine.

Hence, the correct option is, (D)

State the Periodic Law. Why is it so important in the study of chemistry?
gayaneshka [121]

Answer:

Summary. To summarize, the periodic table is important because it is organized to provide a great deal of information about elements and how they relate to one another in one easy-to-use reference. The table can be used to predict the properties of elements, even those that have not yet been discovered.
