Is a straight chain, a linear chain and an unbranched chain the same thing?

Chemistry

Minchanka [31]3 years ago

Answer:

All carbon atoms can be connected to a continuous chain in the straight-chain alkane. In alkanes of a branched-chain, all carbon atoms cannot be connected to a continuous chain as a branch or side chain is part of the carbon chain.

Answer:

In the straight-chain alkanes, each carbon is bound to its two neighbors and to two hydrogen atoms. (In red) Exceptions are the two terminal carbon nuclei, which are bound to only one carbon atom and three hydrogen atoms. (In blue)

A solution is made by mixing 0.82 grams of sodium acetate, 1 mL of 12 M acetic acid (pKa=4.76) and water to give a final volume
kompoz [17]

Answer:

This solution acts as an efficient buffer

Explanation:

the pH of a buffer solution can be described like this: pH=pKa+log\frac{[base]}{[acid]}

[acid]=[acetic acid]=1mL.\frac{12mol}{1000mL} . \frac{1}{1L} = 0.012M

[base]=[sodium acetate]=0.82g.\frac{1mol}{82g} .\frac{1}{1l} = 0.01M

replacing, pH=4.76+log\frac{0.01M}{0.012M} =4.84

If we add an acid, pH will decrease a little bit and if we add a base, pH wil increase a little bit.

lets supose that we change the rate by increasing [base] to 0.1, then

pH=4,76+log\frac{0.1}{0.012} = 5.68

and now lets supose that we increase [acid] to 0.1 pH=4.76+log\frac{0.01}{0.1} = 3.76

Big changes in concentration of base or acid doesn´t produce big changes in pH, in that way the mix of sodium acetate with acetic acid is a good buffer solution.
