The sulfuric acid is used as a catalyst in the given reaction. Sucrose is break down into individual atoms carbon, hydrogen and oxygen.

Oxygen and hydrogen are combine to form water. The heat is released during the reaction and it is exothermic reaction. we can say that heat is given off because it is exothermic while in endothermic heat is taking by the substance.

Exothermic reaction:

The type of reactions in which energy is released are called exothermic reactions.

In this type of reaction energy needed to break the bonds are less than the energy released during the bond formation.

For example:

Chemical equation:

C + O₂ → CO₂

ΔH = -393 Kj/mol

it can be written as,

C + O₂ → CO₂ + 393 Kj/mol

Answer:

It produces free energy.

Explanation:

Photosynthesis is a process which is used by the plant for producing energy in the form of ATP. This energy is used by the plants in different activities which enables the plant to grow and develop successfully. There are some factors which causes change in the rate of photosynthesis means the production of energy for the plant body. If the environmental factors are suitable, more energy is produced through the process of photosynthesis.

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)
