Answer:
0.745 and 0.245
Explanation:
Mole fraction (χ) is the number of moles of a component divided by the total number of moles in a mixture.
We must calculate the moles of each component.
Let CO₂ be Gas 1 and SO₂ be Gas 2.
1. Calculate the moles of each gas.
2. Calculate the total moles.
3. Calculate the mole fraction of each component
Answer :
Lewis-dot structure : It shows the bonding between the atoms of a molecule and it also shows the unpaired electrons present in the molecule. The electrons are represented by dot.
The given molecule is, perbromate ion.
Bromine has '7' valence electrons and oxygen has '6' valence electron.
Therefore, the total number of valence electrons in perbromate ion, = 7 + 4(6) + 1 = 32
According to Lewis-dot structure, there are 14 number of bonding electrons and 18 number of non-bonding electrons.
Formula for formal charge :
The Lewis-dot structure of perbromate ion is shown below.

Answer:</h3>
The structure of Electrophile (2-methylpropan-2-ylium) is shown in attached picture highlighted by green color.
<h3>Explanation:</h3>
Electrophiles are those species which are electron deficient and loves electron. These species often carry positive charge or contain atoms which have incomplete octet.
Also, we know that Benzene undergo Electrophilic Substitution reactions in which hydrogen atom is replaced by other electrophile. In given statement the electrophile to be reacted with benzene to form tert-Butylbenzene is generated from 2-methylpropene. 2-methylpropene when treated with phosphoric acid adds one proton across the double bond (electrophilic addition reaction) and generate a positively charged tertiary carbocation (stable) (highlighted green) which acts as an electrophile. Further on reaction with benzene this electrophile is substituted with proton and results in the formation of tert-Butylbenzene.
Answer: 2.86 inches
Explanation: To find the radius, then, we insert 18 in for the circumference. So 18=2∏r. Solving for r gives 9/∏, or approximately 2.86 inches.
Covalent bond is formed when they share the free electrons in such a way that both of them fill their octet and gain stability.
