Answer:
e.iv, iii, i, ii
Explanation:
Be has electron configuration of 1s^2 2s^2. During bond formation, one 2s electron is promoted to a 2p orbital. Hence two hybrid sp beryllium orbitals are formed. These two hybrid orbitals are used in sigma bond formation to fluorine atoms.
Recall that fluorine has filled 2p orbitals containing lone pairs of electrons. These filled orbitals can interact with the unhybridized 2p-orbitals on beryllium to form pi bonds. This is the reason for the sequence of events chosen in the answer.
Answer:
3 moles of 
is needed for 
to be fully consumed.
Explanation:
For the balanced equation:
⇒ 
First, find the moles of Na corresponding to the 69g used the general definition of mol:
We observe that the equation is balanced and the stoichiometric ratio between them is 1: 1.
According to this, one mole of Na will react with one mole of Cl.
3 moles of is needed for to be fully consumed.
Answer:
the answer is descriptive
Explanation:
descriotive never ever have hypothisis
they have knowledge about the name of medicine and the disease it cured
Adding salt increases the boiling point of the water, which would make it so the water takes longer to get to a boiling point.
