An ether is a compound that has two functional groups separated by an oxygen. The typical structure appears like this: R - O - R', where R and R' are the functional groups. R and R' can only be alkyl and aryl groups. Take for example the simplest ether, Dimethyl ether. The formula is given as CH3OCH3, where there are two methyl groups on each side of the ether. Notice that CH3 is a methyl group, which is an alkyl group.
I'm not sure, however if you put sugar in water then the sugar particles speed up due to the fact that they dissolve in the water. Hope this helped! : D
Answer:
They form a covalent bond
I think because the CH3COCH3(second picture) has a ketone(the double bond to oxygen C=O) in the chemical structure and I believe ketones lead to stronger IMF than ethers(C-O-C). I am not sure about this, but I hope this answer will at least help give you a hint as to what to look up to figure this out. I'm sorry I couldn't be of more help!
Answer:
Average atomic mass = 24.3051 amu
Explanation:
Average Atomic Mass = (Mass of Isotope 1 x Fractional Abundance of Isotope 1) + (Mass of Isotope 2 x Fractional Abundance of Isotope 2) + ......
For 24 Mg
Mass = 23.985 amu
Fractional Abundance = 0.7899
Mass * Fractional Abundance = 18.9458
For 25 Mg
Mass = 24.986 amu
Fractional Abundance = 0.10
Mass * Fractional Abundance = 2.4986
For 26 Mg
Mass = 25.983
Fractional Abundance = 0.1101
Mass * Fractional Abundance = 2.8607
Average atomic mass = 24 Mg + 25 Mg + 26 Mg
Average atomic mass = 18.9458 + 2.4986 + 2.8607
Average atomic mass = 24.3051 amu
