If this is scientific notation, then the answer is 22290000, or 2.229x10^7
Answer:
None
Explanation:
Isomers are organic compounds that have the same molecular formula but different structural formula. What this mean is that these isomers have different arrangement of their atoms. Hence, they belong to different homologous series and exhibit different chemical properties. Hence, it is enough to access whether two different compounds are isomeric using their chemical formula as a yardstick.
Now let us look at our answers. We can see that none of the pairs have the same molecular formula
Answer:
To balance the reaction, we should put a 4 in front of Al
Explanation:
<u>Step 1:</u> Data given
AI+3O2->2AI2O3
<u>Step 2:</u> Balance the equation
On the right side we have 2*3 = 6 oxygen atoms
On the left side we have 3*2 = 6 oxygen atoms as well, so those are on both side balanced
On the right side we have 2*2 = 4 Al atoms
On the left side we have only 1 Al atom
We should multiply this by 4 (place a 4 in front of the Al)
4AI + 3O2 → 2AI2O3
Now al atoms are balanced on both sides.
Answer:
The value of Kp for the system = 0.0128 atm
Explanation:
Let, the gaseous substance is SO₂Cl₂
SO₂Cl₂ ⇄ SO₂ + Cl₂
Initially x 0 0
At equilibrium (x - 14.5%x) 14.5%x 14.5%x
= 85.5 % x
Total moles of gases at equilibrium
= 85.5 % x + 14.5%x + 14.5%x
= 114.5 % x
Partial pressure of SO₂ (
) = ![\frac{14.5x}{114.5x} X0.67= 0.08](https://tex.z-dn.net/?f=%5Cfrac%7B14.5x%7D%7B114.5x%7D%20X0.67%3D%200.08)
Partial pressure of Cl₂ ![(Pcl_{2}) =\frac{14.5x}{114.5x} X0.67 = 0.08](https://tex.z-dn.net/?f=%28Pcl_%7B2%7D%29%20%3D%5Cfrac%7B14.5x%7D%7B114.5x%7D%20X0.67%20%3D%200.08)
Partial pressure of SO₂Cl₂ ![(Pso_{2}cl_{2} )=\frac{85.5x}{114.5x} X0.67= 0.5](https://tex.z-dn.net/?f=%28Pso_%7B2%7Dcl_%7B2%7D%20%20%29%3D%5Cfrac%7B85.5x%7D%7B114.5x%7D%20X0.67%3D%200.5)
So,
![Kp = \frac{Pso_{2} XPcl_{2} }{Pso_{2}cl_{2}}\\ \\=\frac{0.08X0.08}{0.5} \\\\=0.0128](https://tex.z-dn.net/?f=Kp%20%3D%20%5Cfrac%7BPso_%7B2%7D%20XPcl_%7B2%7D%20%7D%7BPso_%7B2%7Dcl_%7B2%7D%7D%5C%5C%20%5C%5C%3D%5Cfrac%7B0.08X0.08%7D%7B0.5%7D%20%5C%5C%5C%5C%3D0.0128)
Energy level and spectral line
Explanation:
The energy levels and their spectral lines are related.
Based on the Bohr's model of the atom, he suggested that electrons occupy specific spherical orbits.
These orbits are called energy levels around the nucleus.
The spectral lines are the different colors emitted by atoms when they absorb or lose energy.
- Electrons can transition between different energy levels when they acquire enough energy that corresponds to that of the energy level
- By doing so, they emit energy in the process and this is seen as visible spectral lines.
- Spectral lines are usually studies in order to gain more information about the properties of atoms.
