Describe how gasoline, as a fuel, can undergo a chemical change.
kvasek [131]

Answer with Explanation:

A "chemical change" occurs when the structure of the molecules change. If there's no change in structure, it is called a "physical change." This also means that a <em>chemical reaction </em>has to occur for something to be considered a chemical change.

Gasoline when used as a fuel is being transformed into other forms of energy. It undergoes a process called <em>"combustion."</em>

When used as a fuel for cars, <em>the gasoline is being burned to produce </em><u><em>heat energy.</em></u> This energy is then converted into <u><em>mechanical energy</em></u> that allows the car to move. Clearly, the gasoline has undergone a chemical change.

A 2.0 L container of nitrogen gas had a pressure of 3.2 atm. What volume would be necessary to decrease the pressure to 1.0 atm
beks73 [17]

Answer:

6.4 L

Explanation:

When all other variables are held constant, you can use Boyle's Law to find the missing volume:

P₁V₁ = P₂V₂

In this equation, "P₁" and "V₁" represent the initial pressure and volume. "P₂" and "V₂" represent the final pressure and volume. You can find the theoretical volume by plugging the given values into the equation and simplifying.

P₁ = 3.2 atm                      P₂ = 1.0 atm

V₁ = 2.0 L                          V₂ = ? L

P₁V₁ = P₂V₂                                                    <----- Boyle's Law

(3.2 atm)(2.0 L) = (1.0 atm)V₂                        <----- Insert values

6.4 = (1.0 atm)V₂                                           <----- Simplify left side

6.4 = V₂                                                        <----- Divide both sides by 1.0

Plz i wanna those answers click on the photo to see all the question they are 2 queastions part A and B
dezoksy [38]

Answer:

a.

Turn paper Blue - these are alkaline/ base substances.

  • Toothpaste
  • Soap
  • Bleach

Turn paper Red - these substances are acidic in nature.

  • Lemon Juice
  • Vinegar
  • Cola drink

b. i. A wasp sting - Lemon juice

ii. A bee sting - Toothpaste

iii. A wasp sting is alkaline which means that running an acidic substance like lemon or lemon juice on it should neutralize it.

A bee sting is acidic so an alkaline substance such as toothpaste should neutralize it as well.
