If a gas is initially at a pressure of 9 atm, a volume of 21 liters, and a temperature of 253 K, and then the pressure is raised
alex41 [277]

Answer:

15.04 mL

Explanation:

Using Ideal gas equation for same mole of gas as

\frac {{P_1}\times {V_1}}{T_1}=\frac {{P_2}\times {V_2}}{T_2}

Given ,  

V₁ = 21 L

V₂ = ?

P₁ = 9 atm

P₂ = 15 atm

T₁ = 253 K

T₂ = 302 K

Using above equation as:

\frac {{P_1}\times {V_1}}{T_1}=\frac {{P_2}\times {V_2}}{T_2}

\frac {{9}\times {21}}{253}=\frac {{15}\times {V_2}}{302}

Solving for V₂ , we get:

<u>V₂ = 15.04 mL</u>

Question 22 3 p Use Bowen's Reaction Series to describe how different igneous rocks form from a single body of magma. Which spec
Leokris [45]

Answer:

The Bowen's reaction series describes how minerals form in sequential order, forming at higher temperature to a lower temperature. There are two branches of crystallization, one is the continuous branch that is on the right and the other is the discontinuous branch that is on the left.

The minerals that are at the top of the Bowen's reaction series forms at a higher temperature.  

In the discontinuous branch, the first mineral to crystallize from the melt is Olivine that forms at a higher temperature of about 1400°C. After crystallization, some melt remains and undergoes fractional crystallization leading to the formation of Pyroxene. Again, with the remaining melt, it reacts and forms Amphibole, followed by Biotite (mica).

In the continuous branch, the first minerals to form are the calcium-rich minerals and successively forms sodium-rich minerals. These minerals that form at a higher temperature are basic in nature and gradually change into acidic minerals.

From both the branches, it commonly forms the mineral Potassium feldspar. After this, the remaining melt combines with the magma and forms Muscovite (Mica), and at a temperature of about 650°C, it forms a more resistant and stable mineral known as the Quartz.

Name all of the alkene isomers, c6h12, that contain a methylene group.
Romashka [77]

Actually, a methylene group is simply any compound which contains a C=C double bond group and the rest are single bonded carbon groups. Some example of the isomers of C6H12 which contains methylene group is:

1-hexene

2,3-dimethyl-2-butene

2,3-dimethyl-1-butene

2-methyl-2-pentene

trans-2-hexene

4-methyl-1-pentene

cis-2-hexene

trans-3-hexene

2-ethyl-1-butene

2-methyl-1-pentene

3,3-dimethyl-1-butene

4-methyl-cis-2-pentene

cis-3-methyl-2-pentene

trans-3-methyl-2-pentene
