I think the answer is A. I know it's Planet X.
Salt is the solute, water is the solvent
The question is incomplete. The image showing the compound and the options in the questions is attached.
Answer:
B
Explanation:
If we closely examine the structure of the compound given in the question, we will notice that the reaction must involve the substitution of the hydroxyl group by chlorine in the parent molecule.
This occurs when the -OH group combines with H^+ to form -OH2^+ which is a good leaving group.
Compound B is formed because, when -OH2^+ leaves, a carbocation is created. This carbocation is stabilized by the alkyl groups attached to the carbon atom bearing the leaving group by +I inductive effect. This carbon atom bearing the leaving group is a tertiary carbon atom thus it forms a more stable carbocation. Hence the product formed.
Answer:
Number of moles = 0.51 mol
Explanation:
Given data:
Mass of CO₂ = 22.4 g
Number of moles = ?
Solution:
Number of moles of CO₂:
Number of moles = mass/molar mass
Molar mass of CO₂ = 44 g/mol
by putting values,
Number of moles = 22.4 g/ 44 g/mol
Number of moles = 0.51 mol
Answer:
True.
Explanation:
The Hund's Rule states that all orbitals must be singled occupied before any orbital is doubly occupied, and all the electrons at the singly occupied orbitals have the same spin number. By doing that, the electrons filled the lowest energy orbitals first.
The 2p level has 3 orbitals: 2px, 2py, and 2pz. So, when filling it, first put an electron in the 2px, then in the 2py, then and the 2pz (all with the same spin). After that, the remains electrons can be paired up.
