Answer:

vegetables and salt

Explanation:

The ideal temperature for fermenting vegetables is between 18⁰-22⁰C. Within this range, the bacteria do their best work, giving high levels of lactic acid. The naturally occurring bacteria on fruits and vegetables is called <em>lactobacillus</em><em>.</em><em> </em>These bacteria convert the sugar to lactic acid, which is what gives that characteristic tangy/sour taste.

in order to dilute 1.0L of a 6.00M solution of sodium hydroxide to 0.500M concentration, how much water (in mL) must you add?
quester [9]
Another M1V1=M2V2 
<span>V1=1.0L </span>
<span>M1=6.00M </span>
<span>M2=0.500M </span>
<span>V2=?? </span>
<span>(6.00M)(1.0L)=(0.500M)V2 </span>
<span>Solve for V2 you get 12L or 12000mL </span>

1. What is an isomer? How many possible isomers of hexane are there? What are the structural differences between these isomers?
VARVARA [1.3K]
Answer 1:
Isomers are compounds with same molecular formula but different structure formula. Isomers are classified into two types
a) Structural/configurational isomers
b) Stereo isomers
In structural/configurational isomers  atom and functional groups are attached in different fashion. Structural isomers may have different functional groups. Structural isomers are further classified as chain isomers, position isomers and functional isomers. In case of stereo-isomers, compounds have same functional group, but different orientation in space. They also have difference activity towards polarized light.

 Answer 2:
Hexane has a molecular formula of C6H14. It exhibits following structural isomers
a) hexane<span>,
b) 2-methylpentane
c)3-methylpentane
d) 2,2-dimethylbutane
e) 2,3-dimethylbutane
Thus, in all there are 5 isomers of hexane

Answer 3: 
</span><span>Butane has two possible isomers but that decane has 75 possible isomers. This can be attributed to the fact that butane has 4 carbon atoms, while decane has 10 carbon atom. As the number of carbon atom increases, there are higher possible sites of linkage, in different fashion. Therefore, as number 69 of carbon atoms increases, number of different possible isomers increases. 

Answer 4:
It has been observed that, though isomers have same molecular formula, but the have different boiling points. Infact, branched isomers have lower boiling point as compared to linear isomers. For example, hexane has boiling point = 69 oC, 2 methyl pentane has boiling point = 60 oC, 2,4, dimethyl butane has boiling point = 58 oC and 2,2 dimethyl butane has boiling point = 50 oC. Thus, it can be observed that branched isomers have lower boiling points as compared to linear isomers. This can be attributed to lower van der Waal's forces of interaction in branched isomers as compared to linear isomers.
