The kb for methylamine (ch3nh2) at 25 ∘c is 4.4×10−4. what is the value of δg at equilibrium?

1 answer:

3 0

Answer is: ΔG for methylamine is 18.85 kJ/mol.
ΔG = R·T·lnK.
ΔG is Gibbs energy.
T is the temperature on the Kelvin scale.
R is ideal gas constant.
R = 8.314 J/mol·K.
T = 25°C = 293.15 K.
Kb = 0.00044.
ΔG = - 8.314 J/mol·K · 293.15 K · ln(0.00044).
ΔG = 18836.85 J = 18.84 kJ.

Which atomic model states that it is impossible to know the exact location of electrons around the nucleus?

Alja [10]

The correct answer is electron-cloud model. This model states that electrons don't go around in an eliptical way but rather completely erratically and uncontrolably and this is why it can't be known where they are or how they will behave. They form sort of like a cloud of many electrons that move erratically so you have to check it to see where it is.

If an atom has an atomic number of 6 and and abdomens mass of 12 how many electrons does it have

Basile [38]

Atomic number refers to the proton number of the atom itself. Number of electrons in an atom (an atom that is not reacted with any other molecules / Just the atom alone), is the same as the number of protons, because each electron has 1 negative charge, and each proton 1 positive charge, where they cancel out on each other to become a neutral charge.

So, when atomic number is 6, proton number is also 6, and number of electrons will also be 6 in that atom.

Hope this helps! :)

Does the size of an object affect its rate of fall?

Vitek1552 [10]

Answer:

The acceleration of the object equals the gravitational acceleration. The mass, size, and shape of the object are not a factor in describing the motion of the object. So all objects, regardless of size or shape or weight, free fall with the same acceleration

The acidity of normal rain water is due to ______. a) SO2 b) CO2 c) NO2 d) NO

Viktor [21]

The correct answer choice is CO₂ (B)

Rainwater naturally contains acids derived from carbon dioxide in the air and reacts with water vapor to form weak acids

H₂O + CO₂ ---> H₂CO₃

<h3>Further Explanation</h3>

Rainwater can cause damage to buildings, animals or plants due to acid rain

Acid rain occurs because other gases in the air mix with toxic gases to form acids

Rainwater naturally contains acids derived from carbon dioxide in the air and reacts with water vapor to form weak acids

H₂O + CO₂ ---> H₂CO₃

However, due to exhaust gases from industry, motor vehicles, or power plants that use fossil fuels containing sulfur to produce sulfur dioxide gas which will produce sulfuric acid

Sulfur combustion from fossil fuels

S + O₂ ----> SO₂

SO₂ produced from this exhaust gas reacts with O₂ oxygen which oxidizes SO₂ to SO₃

SO₂ + O₂ ----> SO₃

SO3 formed reacts with water vapor in the air to produce sulfuric acid as acid rain

SO₃ + H₂O ---> H₂SO₄

To reduce the pollution from this fossil fuel, various studies are now carried out as substitute energy that is more environmentally friendly such as solar energy and so on
