PLEASE HELP A car burns gasoline to create hot air gas that expands to move the pistons in the engine, which causes the car to be able to move.

What energy transformations occur from the fuel to the movement of the car?



Thermal to mechanical

Thermal to chemical to mechanical

Chemical to thermal to mechanical

Chemical to electrical

Answers

Answer 1

Answer:

Chemical to thermal to mechanical

Explanation:

It is because gasoline is chemical energy which turns to thermal. Because it said hot gas which is thermal energy. Then it turns to mechanical for the car to even move.

Answer 2

decreases at higher altitudes.
C. The airplane may need a heat shield for protection from sonic
booms.
O D. The airplane will create more drag at higher altitudes than lower
altitudes.

Isopropyl alcohol is a liquid with a density of 0.785 g/cm^3. How much volume would be taken up be 50.0 grams of isopropyl alcohol

Answers

Answer:

63.94 cm³

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

[tex]volume = \frac{mass}{density} \\ [/tex]

From the question we have

[tex]volume = \frac{50}{0.785} \\ = 63.694267...[/tex]

We have the final answer as

63.94 cm³

A divalent metal oxide contains 60 % of metal. What is atomic weight of metal ?​

Answers

Atomic weight of metal : 24

Further explanation

Proust states the Comparative Law that compounds are formed from elements with the same Mass Comparison so that compounds have a fixed composition of elements

Divalent metal oxide=XO

MW O = 16

MW XO₂ =  X+16

[tex]\tt \%mass=\dfrac{Ar~X}{X+16}\times 100\%\\\\0.6=\dfrac{X}{X+16}\\\\0.6(X+16)=X\\\\0.6X+9.6=X\\\\0.4X=9.6\rightarrow X=24[/tex]

What effect does the spinning of the earth's core have?

B. it creates matter
C. it creates mass
D. it creates the earths magnetic field.

Answers

Answer:

c

Explanation:

its c

Earth contains a spinning electric filed. The spinning of earth core creates its magnetic field. Thus, option D is correct.

What is a spinning body?

A body which rotates in its own axis is called a spinning body. Earth rotates about its along with revolving around sun.  The outer core of earth generates electric current. This is called telluric current.

Flow of this current creates an electric current which is parallels to the surface of earth. The direction of magnetic field lines will be perpendicular to the direction of current. But it comes stronger when parallel to current.

A rotating electric current results in the generation of a magnetic field. Thus spinning of  earth core generates a magnetic field and therefore, option D is correct.

3) Effect on Litmus paper - Dip a blue litmus paper in soda

4) Electrolysis - Add two electrodes to soda and connect a battery.

Does Soda show acidic properties?

Soda, specifically carbonated beverages like cola or soda pop, typically exhibits acidic properties. The acidity of soda is primarily due to the presence of carbonic acid (H₂CO₃), which forms when carbon dioxide gas (CO₂) dissolves in water.

When carbon dioxide is dissolved in water under high pressure, it forms carbonic acid through the following reaction:

CO₂ + H₂O ⇌ H₂CO₃

Would you expect manganese(II) oxide, MnO, to react more readily with HF(aq) or NaOH(aq)?

Answers

Answer:

NaOH(aq)

Explanation:

NaOH(aq) is known to precipitate Mn^2+ ions according to the following reaction; Mn^2+(aq)+2OH^−(aq)↽−−⇀Mn(OH)2(s)

Hence, manganese(II) oxide reacts more readily with NaOH(aq) under ordinary conditions precipitating the metal hydroxide solid. This is one of the characteristic reactions of Mn^2+.

The molecules of Nitrogen, oxygen, and N₂O are  2, 1, and 2 respectively.

What is the chemical equation?

A chemical equation can be defined as the expression of a chemical reaction in terms of the chemical symbols of the substances. A chemical equation has reactants, formed products, and an arrow indicating the direction of the reaction.

The equation in which the number of atoms of each element is equal on either side of the chemical equation of a reaction is called a balanced chemical equation.

According to the law of mass conservation, the total mass of the elements on the reactant side should be equal to the total mass of elements on the product side.

Given, the chemical equation of the reaction of nitrogen ad oxygen gas can be written as:

2N₂  +  O₂ → 2N₂O

The number of molecules of Nitrogen gas is 2 and the molecules of oxygen gas are one and the molecules of N₂O are equal to 2.
