1 answer:

3 0

When you burn a log in your fireplace you are converting c<span>ellulose into carbon dioxide and water.

Wood is made from cellulose. When wood burns, cellulose reacts with oxygen from the air and it forms carbon dioxide and water vapor.

The reaction of the combustion of glucose is as follows:

C₆H₁₂O₆ + 6O₂ = 6 CO₂ + 6H₂O
When wood burns, we notice that it slowly disappears because it passes into the mentioned gases. The ash that is created is part of the wood that did not burn.

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)

True or False? If friction didn’t exist, an object in motion would stay in motion forever.

nata0808 [166]

Answer:

True

Explanation:

Friction is defined as the force that opposes motion when an object is sliding over a surface.

As a result of friction, all objects moving over a surface eventually come to rest over time.If we were to successfully create a friction-less surface, an object will remain in motion forever because it will encounter no opposition to its motion.

Hence, the resistance to the motion of objects over a surface which causes the objects to come to a halt after moving over the surface for some time is called friction.
