What is the final pressure of 1.00 mol of ammonia gas, initially at 1.00 atm, if the volume is:___________.
a. gradually decreased from 78.0 mL to 39.0 mL at constant temperature.
1) 2.00 atm
2) 1.00 atm
3) 0.50 atm
4) Not enough data
b. increased from 43.5 mL to 65.5 mL at constant temperature.
c. decreased by 40% at constant temperature.

Answers

Answer:

The correct answer is a = 2 atm, b = 0.66 atm, and c = 1.66 atm.

Explanation:

a. When the temperature is constant, the ideal gas equation, that is, PV = nRT becomes PV = constant, or P1V1 = P2V2

Based on the given information, the pressure of the gas is 1.00 atm, the V1 of the gas is 78 ml, and the V2 of the gas is 39 ml.  

Now using the above formula we get,  

P2 = (P1V1) / (V2)

P2 = 1 atm * 78 ml/39 ml

P2 = 2 atm.  

b) Now the volume V1 is 43.5 ml, and the volume V2 is 65.5 ml at constant temperature, P1 is 1 atm. Now P2 will be,  

P2 = (P1V1) / (V2)

P2 = 1 atm * 43.5 ml/65.5 ml

P2 = 0.66 atm

c) In the given case, when the volume is decreased by 40 percent, let us consider that the volume, V1 be 100 ml, and the volume V2 be 60 ml, the P1 is 1 atm, now the P2 will be,  

P2 = (P1V1) / (V2)

P2 = 1 atm * 100 ml/60 ml

P2 = 1.66 atm.

How many Kilojoules are obtained from burning 982.6 g of ethanol?

Answers

Answer:

[tex]189kJ[/tex]

Explanation:

Hello!

In this case, since one mole of ethanol release 8,842 J per 1 mole of ethanol, we can write:

[tex]\frac{8,842J}{1molC_2H_6H}[/tex]

Thus, since we need the energy released by 982.6 g of ethanol, we compute the moles in such mass of fuel:

[tex]n=982.6g\frac{1mol}{46.08g} =21.3mol[/tex]

Therefore, the result is:

[tex]\frac{8,842J}{1mol}*21.3mol=188,545J[/tex]

Answer:

The reaction that takes place in a nuclear fission reactor is answer D.

Explanation:

Step-by-step explanation:

Nuclear fission reactions involves the process by which large atomic nuclei are bombarded with energetic particles and release of an enormous amount of nuclear energy, which  mainly ends up as heat energy.

So now, consider the nuclear reaction from D, after the uranium nucleus absorbs the neutron its split into two smaller nuclei (often radioactive themselves), Krypton and Barium and releases more neutrons (or energy).

See explanation

Explanation:

Taking the acid catalysed hydrolysis of fructose C6H12O6, the mechanism begins with the protonation of an -OH group as shown.

This is now followed by dehydration and formation of a keto-enol tautomer. The keto form is now dehydrated followed by the protonation of a second -OH group.

A second dehydration followed by deprotonation leads to the formation of  5-hydroxymethylfurfural.

You weighed out 0.020 g of your crude aspirin product in order to determine the amount of salicylic acid impurity. Following the procedure outlined in the manual, you dissolved the solid and diluted the solution to a final volume of 10.0 mL. If the absorbance of your sample solution was 1.07, what was the percent salicylic acid in your product?
a. 6.4%.
b. 10%.
c. 7.8%.
d. 92%.
e. none of the above.

Answers

Answer:

7.8%

Explanation:

Given that:

The initial mass amount of aspirin = 0.020g

The standard molar mass of aspirin = 240 g/mol

Thus, the number of moles = mass/molar mass

= 0.020/240

= 0.0000833 moles

Now, the molarity of aspirin in the solution(diluted) [tex]C_1[/tex] = [tex]\dfrac{8.33 \times 10^{-5}}{0.01}[/tex]

= [tex]= 8.33 \times 10^{-3} \ M[/tex] (provided the volume v = 0.01 L)

The absorbance of the sample solution A =1.07

The path length (b) = 1 cm

From the standard value of salicylic acid, the coefficient (e)= 139.322 /M/cm

Now; according to Beer's law, the concentration of aspirin is:

A = e×b×c

[tex]c = \dfrac{A}{eb}[/tex]

[tex]c = \dfrac{1.07}{139.322 \times 1}[/tex]

c = 0.00768 M

Finally, relating the concentration of the aspirin, the percentage of salicylic acid the product  [tex]= \dfrac{0.00833-0.00768}{0.00833} \times 100[/tex]

= 7.8%
