Answer:
The answer for 2-hexene is that the structure should have 6 carbon with a double bond beginning on the 2nd carbon atom.
The answer for 1-pentyne is that the structure should have 5 carbon with triple bond beginning on the 1st carbon atom.
Explanation:
<u>2-Hexene</u>
The structural formula for 2-hexene will have 6 carbons because the nomenclature has a -hex prefix, which stands for 6 carbons.
The -ene suffix of the nomenclature means that the organic compound is an alkene. Alkenes are hydrocarbons that contain double covalent bond and have the suffix -ene.
The double bond is on the 2 carbon atom because the nomenclature states that the double bond will be on the 2 carbon atom.
<u>1-Pentyne</u>
The structure will have 5 carbons since the -pent prefix means 5 carbons.
The structure has a triple bond because the -yne suffix means that the structure is an alkyne. An alkyne is a hydrocarbon with triple covalent bonds.
Also, the position of the triple bond is known because the nomenclature of the alkyne states that the triple bond is on the 1st carbon.
Answer:
19.47%
Explanation:
<em>The percentage by mass of </em>
<em> would be </em><em>19.47%</em><em>.</em>
The percentage by mass of a substance in solution is calculated as:

Given that the mole fraction of
= 0.432
The total number of mole fraction of a solution = 1
Hence, mole fraction of water = 1 - 0.432 = 0.568
Mass of water = molar mass x mole
= 98.079 x 0.432 = 42.37 g
Mass of
= molar mass x mole
= 18.02 x 0.568 = 10.24 g
Hence,
<em>%mass of</em>
= 
= 19.47%

Explanation:
In writing the formula of ionic compounds we consider the valency or oxidation state of each ion.
For instance, given the compound iron II oxide. The oxidation states of both iron and oxygen are +2 and -2 respectively. Ignoring the charges, this cancels out and we have FeO as the correct formula of the compound.
For Iron III oxide, the oxidation states of iron and oxygen are +3 and -2 respectively, the both atoms exchange charges. If we ignore the signs and write the exchanged numbers as subscripts we obtain the formula Fe2O3.
Answer:
contrast: unlike carbon dioxide and most of the substance, the phase diagram of water showed and negative slope for the boundary line between the liquid and solid state. this difference has to do with the fact that water activity expands as it goes from the liquid state to the solid state.
compare: carbon dioxide and water vapor temperature is very close to Unity, and then and the phase difference is basically out of the fees for the whole frequency ranges analyzed. The stampabilities are dependents for the normalized standard deviation of carbon dioxide is very similar to those of water vapor and temperature.
