A 2.50L sample of nitrogen gas at a temperature of 308K has a pressure of 1.15atm. What is the new volume of the gas if the pres

Answer:

1.48L

Explanation:

From the question given, we obtained the following data:

V1 (initial volume) = 2.50L

T1 (initial temperature) = 308K

P1 (initial pressure) = 1.15atm

P2 (final pressure) = 1.80atm

T2 (final temperature) = 286K

V2 (final volume) =..?

Using the general gas equation P1V1/T1 = P2V2/T2, the final volume of the gas can obtain as follow:

P1V1/T1 = P2V2/T2

1.15 x 2.5/308 = 1.8 x V2/286

Cross multiply to express in linear form:

308 x 1.8 x V2 = 1.15 x 2.5 x 286

Divide both side by 308 x 1.8

V2 = (1.15 x 2.5 x 286)/(308 x 1.8)

V2 = 1.48L

Therefore, the new volume of the gas is 1.48L

Why are the trends and exceptions to the trends in ionization energy observed? Check all that apply. Ionization energy tends to
NNADVOKAT [17]
The trends and exceptions to the trends in ionization energy observed includes;
B, ionization energy tends to increase across a period because the nuclear charge increases.
C, ionization energy tends to increase across a period because electrons are added to the same main energy level.
E, The ionization energies of elements in Group 13 tend to be lower than the elements in Group 2 because the full s orbital shields the electron, in the p orbital from the nucleus. 
Ionization energies measure the tendency of a neutral atom to resist the loss of electrons. It takes a considerable amount of energy, for example to remove an electron from a neutral fluorine atom to form a positively charged ion. <span />

A chamber with a fixed volume is shown above. The temperature of the gas inside the chamber before heating is 25.2 C and it’s pr
rusak2 [61]

Answer:

Explanation:

Given parameters:

Initial temperature T₁  = 25.2°C  = 25.2 + 273  = 298.2K

Initial pressure  = P₁  = 0.6atm

Final temperature = 72.4°C   = 72.4 + 273  = 345.4K

Unknown:

Final pressure = ?

Solution:

To solve this problem, we use an adaption of the combined gas law where the volume gas is fixed. This simplification results into:

                  \frac{P_{1} }{T_{1} }   = \frac{P_{2} }{T_{2} }

where P and T are temperatures, 1 and 2 are initial and final temperatures.

 Input the parameters and solve;

          \frac{0.6}{298.2}   = \frac{P_{2} }{345.4}  

          P₂   = 0.7atm

A 15.00g solid mixture containing Ca(OH)2, among other non-basic components, was neutralized with 0.2000g of HCl. What was the m
azamat

Answer:

1.373 wt% Ca(OH)₂

Explanation:

Sample mix = 15.0g

Ca(OH)₂(aq) + 2HCl(aq) => CaCl₂(aq) + 2H₂O(l)

moles HCl = 0.2000g / 36 g·mol⁻¹ 0.0056 mol

moles Ca(OH)₂ = 1/2(moles HCl) = 1/2(0.0056 mol) = 0.0028 mol

mass Ca(OH)₂ = 0.0028 mol ( 74 g/mol ) = 0.206 g

mass % Ca(OH)₂ = (0.206/15.0)100% = 1.373 wt%

Draw the product that is expected when hexanoyl chloride is treated with Et2CuLi
PolarNik [594]

Answer:

Product formed is octan-3-one.

Explanation:

Et_2CuLi is a Gilman reagent. General formula of Gilman reagent is R_2CuLi.

Where R is alkyl group or aryl group.

Gilman reagents react with the organo halides to replace halides with alkyl group or aryl group and this reaction is known as Corey–House synthesis.

When hexanoyl chloride is treated with Et_2CuLi, the chloride group of the hexanoyl chloride is substituted with the ethyl group of the Et_2CuLi to form octan-3-one with the removal of EtCu and LiCl.
