Answer:
1,3- dichlorobutane
Explanation:
The IUPAC name of given compound is 1,3- dichlorobutane.
First of all we will select the longest chain.
The given compound is straight chain. So the compound have four carbon atoms means parent name will butane.
Then we will see the position of functional group. Gives the lowest possible number to the functional group attached.
In given compound one chlorine atom is attached on left side and other is on right side. we will start the numbering from left because in this way chlorine will get lowest possible number which 1 and 3.
As we start the numbering from left the one chlorine atom get number one and other is attached on carbon 3 will have number 3.
There are two chlorine atoms so we will give name "dichloro"
The name will be,
⁴CH₃-³CHCl-²CH₂-¹CH₂Cl
1,3- dichlorobutane.
Best Answer
1 mole of a substance contains 6.022x10^23 "units" of that substance.
So 0.187 mol of Na+ is 1.13x10^23 ions (6.022x10^23 x 0.187).
Answer:
Explanation:
Hello,
In this case, the undergoing chemical reaction is:
In such a way, the mercury II sulfate (molar mass 296.65g/mol) is in a 1:1 molar ratio with the mercury II chloride (molar mass 271.52g/mol), for that reason the stoichiometry to find mass in grams of mercury II chloride turns out:
Best regards.
The ph of the best buffer is 4.74
The given acetic acid is a weak acid
The equation of the pH of the buffer
pH = pKa + log ( conjugate base / weak acid ).
For best buffer the concentration of the weak acid and its conjugate base is equal.
pH = pKa + log 1
pH = pKa + 0
pH = pKa
given Ka = 1.8 × 10⁻⁵
pKa = - log ka
pH = -log ( 1.8 × 10⁻⁵ )
pH = 4. 74
Hence the pH of the best buffer is 4.74
