Answer:
3.01×10²⁴ atoms
Explanation:
Our compound is the Na₃PO₄
Sodium phosphate.
We assume, we have 5 moles of the mentioned salt.
1 mol of anything contains 6.02×10²³ atoms.
That's the Avogadro's number. The conversion is:
5 mol . 6.02×10²³ atoms /1mol = 3.01×10²⁴ atoms
Answer:
n .= 1 to 4
Explanation:
From the Planck 5
E = hc/lambda
Where lambda is wavelength
E= hf
We will explain the answer here with respect to wavelength. It should be understood that the higher the wavelength of transition, the lower the frequency.
This means that longer transitions will occur at lesser frequencies. From the options the biggest transition is from 2 to 94, while the smallest is from 1 to 4
The transition from 1 to 4 is expected to have the highest energy as it has the shortest wavelength,
Transition from 2 to 94 has the longest wavelength, lowest energy and least frequency
Answer:
of the reaction is -6313 kJ/mol
of the reaction is -6312 kJ/mol
Explanation:
Therefore, of the reaction is -6313 kJ/mol.
The chemical reaction in bomb calorimeter is as follows.
Therefore, of the reaction is -6312 kJ/mol.
We can approach this problem using the ideal gas law which is as follows:
PV = nRT
P = pressure
V = volume
n = number of moles
R = gas constant, 0.08206 Latm/Kmol
T = temperature
We are asked to solve for temperature and can rearrange the equation to solve for T:
PV = nRT
T = PV/nR
Now we simply plug in the data to solve for T:
T = (4.50 atm)(10.0 L)/(3.00 mol)(0.08206 Latm/Kmol)
T = 183 K
The temperature of the gas is 183 K.
