In a closed container with a fixed volume, when the temperature of a gas doubles, the pressure of the gas is?

nevsk [136]

Answer:

The pressure of the gas is:

Doubled

Explanation:

Byole's Law = Pressure of fixed amount of gas is inversely proportional to Volume at constant temperature.

PV = k = constant

P1V1 = P2V2

Charle's Law: The volume of ideal gas at fixed pressure is directly proportional to Pressure.

V/T = constant

V1/T1 = V2/T2

On combinig the charles and byole's law , we get:

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

Now , According to question :

V2 = V1

T2 = 2(T1)

We have to find the relation between the pressure :

insert the value in the equation

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

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

V1 and V1 & T1 and T1 cancels each other,

So we get

P2 = 2 P1

So the new pressure is double of the original pressure

The percentage composition of acetic acid is found to be 39.9% C, 6.7% H, and 53.4% O. What is the empirical formula of acetic a

anastassius [24]

Answer:

CH₂O

Explanation:

From the question given above, the following data were obtained:

Carbon (C) = 39.9%

Hydrogen (H) = 6.7%

Oxygen (O) = 53.4%

Empirical formula =?

The empirical formula of acetic acid can be obtained as follow:

C = 39.9%

H = 6.7%

O = 53.4%

Divide by their molar mass

C = 39.9 / 12 = 3.3

H = 6.7 / 1 = 6.7

O = 53.4 / 16 = 3.3

Divide by the smallest

C = 3.3 / 3.3 = 1

H = 6.7 / 3.3 = 2

O = 3.3 / 3.3 = 1

The empirical formula => CH₂O

When a kettle is placed on the stove and water begins to boil, the hotter water at the bottom begins to rise and the cooler wate

The hotter water is less dense and rises. The cooler water then sinks because it is more dense.

For a gaseous carbon atom in its' ground state which of the following are possible sets of quantum numbers for two different ele

MAXImum [283]

Answer:

Option e=>

electron 1; n l ml ms = 2 1 0 +1/2.

electron 2;n l ml ms= 2 1 -1 +1/2.

Explanation:

The electronic configuration of carbon in its ground state is 1s2 2s2 2p2. The excited electronic configuration of carbon is given as; 1s2 2s1 2p3 because one of the electrons moves to the 2p sub- orbital because of the absorption of the atom.

Recall that there are four different types of quantum numbers and they are the principal quantum number,n; the Azimuthal quantum number, l; the magnetic quantum number, ml and the spin quantum number, Ms.

Our principal quantum number,n is TWO(2) which is the highest energy level from the electronic configuration written above.

The Azimuthal quantum number is 1 from l= n - 1.

The magnetic quantum number is -1 and 0 because we have two electrons filling the 3 orbitals of 2p sublevels. That is;

2px = -1 , 2py = 0 and 2pz = +1.

Only 2px and 2py will be considered because we have 2 electrons on the 2p in the ground state electronic configuration.

Therefore, the first electron will have ml= 0 and the second electron will have ml= -1.

Spin quantum number, ms; in both electrons the spins is an up spin so we have a +1/2 for both electron.

Hence; electron 1; n l ml ms = 2 1 0 +1/2.

Electron 2;n l ml ms= 2 1 -1 +1/2.

Why are all guys the same. They all cheat and break my heart. Why do they do it?

PilotLPTM [1.2K]

Not all guys will break your heart and act selfish. When you find the right one he will treat you like a queen and you’ll never have to worry about him being unfaithful. I know it doesn’t help a hurting heart, but you WILL find your soulmate one day! Just keep faith! Best wishes!
