Classifying is the grouping together of items that are alike in some way. Answer: Making models involves creating rep- resentations of complex objects or processes.
Answer:
Polar covalent.
Explanation:
The covalent bonds are therefore polar, and the oxygen atoms have a slight negative charge (from the presence extra electron share), while the hydrogens are slightly positive (from the extra un-neutralized protons). Opposite charges attract one another.
Answer:
The pH is 4.76 (option C)
Explanation:
pH of a solution = TO BE DETERMNED
[sodium acetate] = 1M ; [acetic acid] = 1M
K = [H+] [A-] / [HA]
K = [H+] [1] / [1]
K = H
pH = pK
⇒ now pH is equal to pK
⇒ The value of pK is given which is 4.76
⇒ This means the value of the pH is also 4.76
I believe that A is the answer. :)
