Answer:
P = 0.75 atm
Explanation:
Using Boyle's law
Given ,
<u>For Bulb A</u>
Pressure = 190 torr
The conversion of P(torr) to P(atm) is shown below:
So,
Pressure = 190 / 760 atm = 0.25 atm
Volume = 200 mL
For Bulb B
Pressure = 1 atm
Volume = 400 mL
For Bulb C
Volume = 1.00 L = 1000 mL
Pressure = 75.994 kPa
The expression for the conversion of pressure in KiloPascal to pressure in atm is shown below:
P (kPa) = P (atm)
75.994 kPa = atm
Pressure = 0.75 atm
Also, Total volume, V = 200 + 400 + 1000 mL = 1600 mL
Using above equation as:
We get, Total pressure, P = 0.75 atm
In thermodynamics, work of a system at constant pressure conditions is equal to the product of the pressure and the change in volume. It is expressed as follows:
W = P(V2 - V1)
W = 1.3x10^5 (2x6 - 6 )
W = 780000 J
Hope this answers the question. Have a nice day.
Explanation:
The orbital for fluorine is 1s 2s 2p. All of the boxes should be filled COMPLETELY until you can't no more. How do you know if you can't anymore? By the <u>atomic number</u> of the element. The atomic number for fluorine is 9. So, you keep adding arrows starting from the first box all the way to the last until you have reached the atomic number, in this case, 9.
Answer:
Answer:
For the reaction CH3COOH→CH3COO– + H+
Among the given statements which is the correct statement?
CH3COOH is a Brønsted-Lowry base.
CH3COO– is an Arrhenius base.
CH3COOH is a Brønsted-Lowry acid.
CH3COO– is a Lewis base.
Explanation:
Bronsted acid is the proton donor.
Bronsted base is the proton acceptor.
Arrhenius base is the one that releases OH- ions when dissolved in water.
Lewis base is the one that is an electron-pair donor.
In the given reaction,
CH3COOH→CH3COO– + H+
Acetic acid releases a proton.
So, it is a proton donor.
Hence, It is a Bronsted-Lowry acid.
Third option is the correct answer.
