The balanced equation for the above double displacement reaction is as follows;
2KCl + Pb(NO₃)₂ ---> PbCl₂ + 2KNO₃
Stoichiometry of KCl to PbCl₂ is 2:1
This means that 2 mol of KCl would react with every 1 mol of PbCl₂
The molarity of KCl - 0.596 M
in 1 L of KCl there are 0.596 mol
Therefore in 10.0 mL of KCl there are -
Number of KCl moles reacted - 0.00596 mol
according to stoichiometry
number of PbCl₂ moles formed - 1/2 x number of KCl moles reacted
Therefore number of PbCl₂ moles formed - 0.00596 mol/2 = 0.00298 mol
molar mass of PbCl₂ - 278 g/mol
mass of PbCl₂ formed - 278 g/mol x 0.00298 mol = 0.828 g
Answer:
3,5-dichlorohex-1-ene
Explanation:
The compound is; H2C=CH-C(Cl)H-CH2-C(Cl)H-CH3. We can rightly call this compound by the name, 3,5-dichlorohex-1-ene.
We arrived at this name by first counting the longest parent carbon chain, that gives hexane. The compound has a double bond at the 1-position. Also, there are two substituent chlorine atoms at positions 3 and 5 in the structure, hence the name given.
Lurf shows helium. Jeptum shows oxygen. Noofnog shows neon. Phleegum shows sodium. Vorkel shows silicon. Dogzall shows chlorine. The metalloid is Vorkel.
