N=3.5 mol
c=3.5 mol/L
n=cv
v=n/c
v=3.5/3.5=1.0 L
A) 1.0 liter of solution
Answer:
477 °C
Explanation:
Step 1: Given data
- Initial pressure (P₁): 1.0 atm
- Initial temperature (T₁): 27 °C
- Final pressure (P₂): 2.5 atm
Step 2: Convert 27 °C to Kelvin
We will use the following expression.
K = °C + 273.15 = 27 + 273.15 = 300 K
Step 3: Calculate the final temperature (T₂)
If we assume constant volume (before the can explodes) and ideal behavior, we can calculate the final temperature using Gay-Lussac's law.
T₁/P₁ = T₂/P₂
T₂ = T₁ × P₂/P₁
T₂ = 300 K × 2.5 atm/1.0 atm = 750 K
In Celsius,
°C = K - 273.15 = 750 - 273.15 = 477 °C
<u>Answer:</u> The correct answer is Option 1.
<u>Explanation:</u>
There are three subatomic particles in an atom. They are: electrons, protons and neutrons.
- <u>Protons:</u> They carry positive charge and are found in nucleus.
- <u>Electrons:</u> They carry negative charge and are found around the nucleus.
- <u>Neutrons:</u> They dos not carry any charge and are found in nucleus.
Mass of protons and neutrons are almost same and they both contribute to the mass of an atom.
Mass of electrons is very negligible as compared to protons and neutrons.
Masses of the subatomic particles:
Mass of protons = 1.007276 u
Mass of neutrons = 1.008664 u
Mass of electrons = 0.00054858 u
Hence, the correct answer is Option 1.
Answer:
During the uncoupling of electron transport chain energy that is generated by the transport of electron along with proton, is released as heat.
Explanation:
The proton motive force generate energy for the phosphorylation of ADP with inorganic phosphate to form ATP an energy rich molecule during the process called oxidative phosphorylation.
There are some chemical agents knowns as uncouplers for examole thermogennin,2'4-dinitophenyl.They does not interfere with the transport of electrons through various electron carriers which generate energy,but uncouplers blocks the phosphorylation step.
As a result the energy that is released during transport of electron, is liberated as heat.
Add up all the molar masses of the elements multiplied by the number of atoms each.
Molar mass of carbon = 12.01g
Molar mass of hydrogen = 1.01g
Molar mass of oxygen = 16g
9(12.01) + 8(1.01) + 4(16)
Molar mass of aspirin = 180.17g
