Chemistry

Answer:

See explanation.

Explanation:

Hello,

In this case, we can realize that water has a very simple atomic structure which consists of two hydrogen atoms bonded to one oxygen atom. The nature of the atomic structure of water causes its molecules to have unique electrochemical properties. The hydrogen side of the water molecule has a slight positive charge whereas at the other side of the molecule a negative charge exists. This molecular polarity causes water to be a powerful solvent and is responsible for its strong surface tension.

Moreover, water is involved in several both inorganic and organic chemical reactions leading to hydration, for example, the conversion of alkenes to alcohols, the hydrolysis of acyl halides, anhydrides, esters and amides to carboxylic acids and the hydration of a raft of inorganic salts that exist as hydrates only, such as copper (II) sulfate pentahydrate and so.

Best regards.

A sports utility vehicle gets an average gas mileage of 17.5 miles per gallon. A hybrid version of this SUV averages 21.5 mpg. I
ZanzabumX [31]

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)
