The products for the complete combustion of a hydrocarbon in excess air is carbon dioxide and water. Any hydrocarbon when reacted with oxygen will always yield the said products. Incomplete combustion, on the other hand, yields carbon monoxide and water.
Given :
A student has a 1 g sample of each of the following compounds: NaCl, KBr, and KCl.
To Find :
The samples in order of increasing number of moles in the sample.
Solution :
Molecular mass of NaCl, KBr, and KCl is 58.5 g/mol , 119 g/mol and
74.5 g/mol respectively .
Moles of NaCl , .
Moles of KBr , .
Moles of KCl , .
The order of moles in increasing order is :
KBr , KCl and NaCl .
Hence , this is the required solution .
Answer:
an increasng atomic number/ increasing proton count
Explanation:
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.
False. Solids have a definite shape and volume. Cutting a paper (solid) in half will alter the shape of the original solid and give it a new shape and volume instead. A solid will always have a definite shape. If not, it's not a solid.
