Answer:

<h2>The answer is $6.52.</h2>

Explanation:

Firstly, let's check out the given:

1. Sports Utility Vehicle's (Original SUV) avg gas mileage - 17.5 miles per gallon (mpg)

2. SUV's (Hybrid SUV) avg gas mileage - 21.5 miles per gallon (mpg)

3. Gas price - $2.59 per gallon

What is asked? How much would you save driving 237 miles in the hybrid SUV compared to the original SUV?

Next, you have to know how much gallons each car consumes upon driving 237 miles. You can do division in this step.

1. Original SUV = 237 miles ÷ \frac{17.5 miles}{gallon} = 13.54 gallons

2. Hybrid SUV = 237 miles ÷ \frac{21 miles}{gallon} = 11.02 gallons

Now that you know how much gallons each car consumes, you can now get the gas price for the gallons.

1. Original SUV = 13.54 gallons × $2.59 per gallon = $35.06

2. Hybrid SUV = 11.02 gallons × $2.59 per gallon = $28.54

In order to check the difference, you have to subtract.

  • $35.06 - $28.54 = $6.52 (this is the amount of money that you can save driving 237 miles in the hybrid SUV compared with the original SUV)

Consider a disubstituted aromatic compound. The parent name is benzene and there is a chloro and bromo substituent. Disubstitute
Marina86 [1]

Answer:The correct names for the structure are:

--> 1. 1-bromo-3-chlorobenzene.

--> 3. meta-bromochlorobenzene.

--> 6. m-bromochlorobenzene.

Explanation:

Benzene is the simplest member of the aromatic hydrocarbons. It has a ring structure consisting of six carbon and six hydrogen atoms. This equally means that a benzene can have up to six substituents. One of the chemical properties is that benzene and other members of its series undergo substitution reaction whereby one or more of its six hydrogen atoms is replaced by monoatomic reagents.

Disubstituted benzene consists of two substituents which are described based on either numerical locants or specific words for the three possible forms.

The numerical locant method are used the same naming substitutes of other hydrocarbons. From the question, the numerical locant method was derived through using the following steps:

--> the functional group is benzene

--> there are two substituents which includes bromine( written as bromo) and chlorine ( written as chloro)

--> while placing the number, it's done alphabetically ('1-bromo' comes before '3-chloro') in a clockwise manner. This is to give chorine the lowest locant number.

The second naming method for a disubstituted benzene is the the ortho-, meta-, para- (or their singel letter equivalent) nomenclature method. This is only used for benzene structures.

--> ortho or O : this is used when the substituents are close to each other in the benzene ring.

--> meta or (m) : This is used when the substituents are separated by one carbon in the benzene ring.

--> para or (p): This is used when the substituents are across each other in the benzene ring

From the question, the bromine substituent is separated from the chlorine by one carbon atom, therefore it's meta-bromochlorobenzene or m-bromochlorobenzene.

A wooden block has a mass of 20 g and dimensions of 5 cm x 1 cm x 1 cm.
marta [7]

Answer:

V = 5 cm³

ρ = 4 g/cm³

Explanation:

Step 1: Calculate the volume (V)

We have a wooden cuboid of dimensions 5 cm × 1 cm × 1 cm. We can calculate its volume using the following expression.

V = 5 cm × 1 cm × 1 cm

V = 5 cm³

Step 2: Calculate the density (ρ)

The density is equal to the mass divided by the volume.

ρ = m / V

ρ = 20 g / 5 cm³

ρ = 4 g/cm³

Answer the questions in the table below about the shape of the phosphorus hexachloride (PCI^1_6) anion. What word or two-word ph
REY [17]

Shape of PCl₆⁻¹, is octahedral.

Hybrdisation of PCl₆⁻¹ is sp³d².

This can be seen the image attached.

The angle between phosphorous and chlorine is 90⁰C. As it has octahedral geometry.

So the answer is as follows:

Shape of PCl₆⁻¹, is octahedral.

Hybrdisation of PCl₆⁻¹ is sp³d².

The angle between phosphorous and chlorine is 90⁰C.
