Alexander Fleming discovered a new type of medicine (penicillin) that could treat infections.
Answer:
1–ethoxybutane
Explanation:
In naming the above compound, the following must be observed:
1. The longest chain gives the root name of the compound.
2. The shorter chain is named as substituent together with the oxygen group as alkoxy.
3. Locate the position of the alkoxy group by giving it the lowest low count.
4. Combine the above to obtain the name of the compound.
Now we shall name the compound as follow:
1. The longest chain is carbon 4 i.e butane.
2. The shortest chain is ethyl (i.e –CH₂CH₃). This is named together with the oxygen atom as ethoxy.
3. The ethoxy group is located at carbon 1 of the butane chain since it is the functional group of the chain.
4. The name of the compound is:
1–ethoxybutane.
Answer:
18
Explanation:
Sabemos que la fórmula química del agua es H2O.
Usando la información que; H = 1, O = 16, podemos calcular la masa molar del agua de la siguiente manera
[2 (1) + 16] = 18
Por tanto, la masa molar del agua es 18
Its A It provides support for the body
The bones(Cartilage?) provide support for the body
No you couldn’t, because a drop of water has approximately 1.61*10^21 molecules, so this would be slightly more than a drop of water
