In collecting the precipitate, it is inappropriate to heat <span>the reacted mixture and evaporate off the water because it is possible that the mixture contains other substances that precipitates as well when the mixture is being heated so you will not be able to collect what you want.</span>
Answer:
Hey there,
Your answer is iii. Brown cows produce white milk. (1 point) <u>and</u> ii. Brown cows never produce chocolate milk. (1 point)
You already know from the basic understanding that chocolate comes from beans, not cows, and is added to milk, and thereby- brown cows do not produce chocolate milk. You also know that they produce white milk.

if you have any questions I <em><u>INSIST</u></em> you ask them in the comments.
Functional groups create reactive sites in molecules.
The polar part of a molecule that can hydrogen bond to water is said be hydrophilic.
Pi (π) bonds create active sites and will react with electron-deficient species.
A electronegative heteroatom like nitrogen, oxygen, or a halogen makes a carbon atom electrophilic.
(carbon will have less electronic density, which is attracted by the more electronegative heretoatoms, and it will tend to attract electron rich chemical species, and in this situation we say that the carbon atom is electrophilic).
The nonpolar part of a molecule that is not attracted to water is said to be hydrophobic.
A lone pair on a heteroatom makes it basic and nucleophilic.
(the heteroatom with the lone pair will tend to attract electron poor chemical species, and in this situation we say that the heteroatom is nucleophilic).
The correct answer is B) Basic. Hope this helps.
