Answer:
THE PRESSURE OF THE TIRE ON THE TRIP HOME AT THE ROAD SURFACE TEMPERATURE OF 32°C IS 160 kPa.
Explanation:
Initial Pressure = 75 kPa
Initial temperature = 15 °C
Final temperature = 32 °C
Final pressure = unknown
Using the combined equation of gases;
P1V1/T1 = P2V2/ T2
Since the tire will have the same volume of air in it showing that volume of constant both at the repair shop and on the road surface.
The relationship between pressure and temperature is used with constant volume.
P1/T1 = P2/ T2
75 kPa / 15 °C = P2 / 32 °C
P2 = 75 kPa * 32 °C / 15 °C
P2 = 2400 kPa °C / 15 °C
P2 = 160 kPa.
So therefore, the pressure of the tire on the trip home when the temperature of the road surface is 32°C is 160 kPa.
Answer:
Explanation:
Diels-Alder reactions are cyclo-additional reactions between conjugated dienes and a dienophile (a substituted alkene compound for example acrylic acid) to produce a ring structure of cyclohexene compounds.
From the image attached below, we will see the reaction between 2,3-dimethylbuta-1,3-diene which is a conjugated diene with acrylic acid to produce a Diel-Alder adduct as the product. From the reaction, a single new π-bond and two σ-bonds are produced.
Answer:
The answer to your question is: Uranium.
Explanation:
Elements of the f-block are the elements of the inert earth transition metals. They the located in 2 rows beow the other elements in the periodic table. They included lathanides and actinides.
Oxygen belongs to the p-block, so it is not oxygen the answer.
Iron belongs to the d-block. This is incorrect.
Argon belongs to the p- block, this option is incorrect.
Uranium belongs to the f-block.
Answer:
Explanation:
Their role is to compose proteins. Amino acids have many biologically important functions. They are also energy metabolites,many of them are essential nutrients. Amino acids can function as chemical messengers in communication between cells.
