Answer:

a) The formal charge on N is 0 in both species.

Explanation:

The formal charge is calculated using the formular;

FC = V-N-B/2

Where;

V = Number of Valence electrons

N = number of nonbonding valence electrons

B = total number of electrons shared in bonds

In NO2-;

The formal charge of N is given as;

FC = 5 - 2 - 6/2

FC = 0

In HNO2

The formal charge of N is given as;

FC = 0

The correct option is;

a) The formal charge on N is 0 in both species.

Stickleback fish are collected from a lake in Alaska. 600 from the sample are spineless, which is a recessive trait in the fish.
tekilochka [14]

Answer:

Frequency of spinal trait in the population = 0.11

Explanation:

Given:

Total spineless trait = 600

Number of spinal trait = 80

Find:

Frequency of spinal trait in the population

Computation:

Total population = Total spineless trait + Number of spinal trait

Total population = 600 + 80

Total population = 680

Frequency of spinal trait in the population = Number of spinal trait / Total population

Frequency of spinal trait in the population = 80 / 680

Frequency of spinal trait in the population = 0.11

Identify the correct formula for Beryllium Phosphate.
ivanzaharov [21]
<span>The correct formula for Beryllium phosphate is Be3(PO4)2 Beryllium has a charge of +2 and phosphate has a charge of -3. So to make the charge equal to zero, 3x +2 = 6, and 2 x-3 = -6 -6 + +6 = 0</span>

Sodium tert-butoxide (NaOC(CH3)3) is classified as bulky and acts as Bronsted Lowry base in the reaction. It is reacted with 2-c
IceJOKER [234]

Answer:but-1-ene

Explanation:This is an E2 elimination reaction .

Kindly refer the attachment for complete reaction and products.

Sodium tert-butoxide is a bulky base and hence cannot approach the substrate 2-chlorobutane from the more substituted end and hence major product formed here would not be following zaitsev rule of elimination reaction.

Sodium tert-butoxide would approach from the less hindered side that is through the primary centre and hence would lead to the formation of 1-butene .The major product formed in this reaction would be 1-butene .

As the mechanism of the reaction is E-2 so it will be a concerted mechanism and as sodium tert-butoxide will start abstracting the primary hydrogen through the less hindered side simultaneously chlorine will start leaving. As the steric repulsion in this case is less hence the transition state is relatively stabilised and leads to the formation of a kinetic product 1-butene.

Kinetic product are formed when reactions are dependent upon rate and not on thermodynamical stability.

2-butene is more thermodynamically6 stable as compared to 1-butene  

The major product formed does not follow the zaitsev rule of forming a more substituted alkene as sodium tert-butoxide cannot approach to abstract the secondary proton due to steric hindrance.

How many grams of oxygen are required to react with 13.0 grams of octane (C8H18) in the combustion of octane in gasoline?
egoroff_w [7]

Grams of oxygen are required to react with 13.0 grams of octane (C8H18) in the combustion of octane in gasoline is 45.5g

Octane is a hydrocarbon which burns in gasoline in presence of oxygen according to the given balanced chemical equation,

2C₈H₁₈ + 25O₂------> 16CO₂ + 18H₂0

Molar mass of octane = 114.23g/mol

Molar mass of Oxygen = 32g/mol

According to the stiochiometry of the balanced equation the mole ratio of Octane and Oxygen is 2:25

2 mole of octane needs 25 mole of oxygen

1 mole of octane needs 12.5 moleof oxygen

114.23g of octane needs 400g of oxygen

13g   of octane  needs 45.5g of oxygen

Mass of oxygen needed =45.5g

Hence, the Mass of oxygen needed is 45.5g for the combustion of octane in gasoline.
