Answer:
See explanation.
Explanation:
Since potassium tert-butoxide is a strong bulky base, we expect that an elimination reaction predominates.
This reaction is expected to occur by E2 mechanism. The cis isomer of 1-bromo-4-tert-butylcyclohexane is known to react faster by E2 mechanism because it fulfills the anticoplanar arrangement required for for E2 mechanism, where the leaving group and adjacent proton must be anti to each other and in the same plane. The trans isomer can not fulfill this requirement.
Since both atoms are the same and are both nonmetals, they would form a Nonpolar covalent bond. This bond occurs when usually atoms of the same element or atoms of propriety electronegativity differences are sharing electrons to form bonds. There is an equal sharing of valence electrons in this chemical bond.
Answer:
The new pressure is 3850 torr.
Explanation:
The relation between volume and pressure is inverse as per Boyle's law. Its mathematical form is given by :
Here,
Let 
is the new pressure. So using Boyle's law we get :
or
So, the new pressure is 3850 torr.
<h3>
Answer:</h3>
2.5 moles
<h3>
Explanation:</h3>
<u>We are given;</u>
We are required to determine the number of moles of sodium.
- We know that, 1 mole of an element contains a number of atoms equivalent to the Avogadro's number, 6.022 × 10^23.
- That is, 1 mole of an element = 6.022 × 10^23 atoms.
Therefore;
1 mole of sodium contains 6.022 × 10^23 atoms
To get the number of moles;
= Number of atoms ÷ Avogadro's number
= 1.5 × 10^24 atoms ÷ 6.022 × 10^23 atoms/mol
= 2.49 moles
= 2.5 moles
Therefore, 2.5 moles of sodium contains 1.50 × 10^24 sodium atoms
