The question requires us to draw the structural formula, provide the name and highlight any functional groups for the compound: diethyl ether.
The molecule diethyl ether can be represented as it follows, with two ethyl groups (-CH2CH3) bonded to a oxygen atom:
Note that the functional group ether (R-O-R) is present in the structre and highlighted in blue in the image. The official name of diethyl ether is ethoxyethane.
Answer:
Option A. 1.8×10²⁴ molecules.
Explanation:
Data obtained from the question include:
Number of mole of methane = 3 moles
Number of molecules of methane =?
From Avogadro's hypothesis, we understood that 1 mole of any substance contains 6.02×10²³ molecules.
Thus, 1 mole of methane equally contains 6.02×10²³ molecules.
With the above information in mind, we can obtain the number of molecules in 3 moles of methane as follow:
1 mole of methane contains 6.02×10²³ molecules.
Therefore, 3 moles of methane will contain = 3 × 6.02×10²³ = 1.8×10²⁴ molecules.
Thus, 3 moles of methane contains 1.8×10²⁴ molecules.
As the earth is in the form of a sphere, the angle of incidence of the sun's rays at the earth's surface increases from the equator towards the poles and therefore the amount of heat received on a GIVEN AREA diminishes in the same direction. Temperature is therefore normally hottest near the equator and coolest near the poles.

North Carolina winter weather evolves from complex meteorological patterns that are difficult to forecast, and which lead to considerable variability in weather conditions across the state. As a result, the frequency and intensity of winter weather events are highly variable and dependent upon large (synoptic) and small (mesoscale) scale atmospheric patterns.
The jet stream is a narrow band of strong winds in the upper atmosphere. In winter, it separates cold, Arctic air masses from warmer, continental air masses. Certain regions of the jet are also favorable for storm development, while others are not.<span>The orientation and location of the jet stream has large implications on the weather year-round, but even more so in winter because the jet stream is stronger due to a large temperature contrast from the north to south.
i know nothing about science but then it just comes to me and i get it right.
