Explanation:
Water Content of Epidermal Cells
Temperature: Increase in the temperature causes stomata to open
Answer: The answer is D. This has a Carboxylic Acid group, and is acetic acid, or Ethanoic Acid.
ALWAYS LOOK for the Functional Group in question.
A. Would likely not stay in water, or at least not be acidic, for it is butane gas.
B. Is 1-propanol, and alcohols are not acidic as a rule. Certainly not in water.
C. This is an Ether. It will not give up an H+, it it not an acid.
E. This functional group is an amine, which is more “base” like, since the lone pairs of the Nitrogen atom would tend to attract a H+.
Because copper sulphate is not an ionic substance, no bonds are changed when it is dissolved. Thus it has to be a physical change
Their identified by the number of protons they have in the nucleus which = their electrons.
