Answer:
Explanation:
We have the following chemical reaction:
3 HBr + Al(OH)₃ → 3 H₂O + AlBr₃
This reaction is a double-displacement reaction because the reactant exchange between themselves atoms or group of atoms. The general representation of this kind of reaction is AB + CD → AC + BD

Answer:
σ*2pₓ, also called 
Explanation:
I have drawn the MO diagram for fluorine below.
Each F atom contributes seven valence electrons, so we fill the MOs of fluorine with 14 electrons.
We have filled the
and
MOs.
They are the highest occupied molecular orbitals (HOMOs).
The next unfilled level (the LUMO) is the σ*2pₓ orbital. If you use the symmetry notation, it is called the
orbital.
This is the orbital that fluorine uses when it acts as an electron acceptor.
Answer:
625=275
240=x
625x=275×240
625x=66000
x=66000/625
x=105 .6
Explanation:
If 625°C gives us 275KPa then 240°C will give us the the sum of 275×240 divided by 625
