Bees and flowers both belong to the domain Eukarya. Using this information, how are bees and flowers similar?
Step2247 [10]
The answer is both are made of cells that contain a nucleus. Since they made up of cells that have a nucleus enclosed within membranes, bees and flowers can be classified under Domain Eukarya. Animals are heterotrophic, have no cell walls and no cloroplasts, while plants are autotrophic, have cell walls with cellulose and have chloroplasts.

Write a net ionic equation for the reaction that occurs when excess hydroiodic acid and nickel(II) sulfide are combined.
tiny-mole [99]

Explanation:

Step 1: Write the balanced "molecular" equation:

2HI(aq) + NIS (s) → NiI₂(aq) + H₂S(g)

Step 2: H₂S is written in molecular form. Consult the solubility and net ionic equation rules on the information page to determine which of the other substances will dissociate:

2HI(aq) + NIS (s) → NiI₂(aq) + H₂S(g)

yes no yes

Step 3: Dissociate all soluble salts, strong acids, and strong bases (except calcium hydroxide). Leave together all "not soluble" salts and weak acids or bases:

{2H₃O}^{ + }  (aq) +  {2I}^{ - }  (aq) + NiS(s)→  { Ni}^{2 + }(aq) +  {2I}^{ - }(aq) + H₂S(g) + 2H₂O(l)

Step 4: Cross out "spectator ions" that appear on both sides of the reaction (these ions do not participate in the chemistry) and rewrite the "net" reaction using the smallest possible coefficients:

{2H₃O}^{ + } (aq) + NiS(s) →   { Ni}^{2 + } (aq) + H₂S(g) + 2H₂O(l)

What is the pH of a solution made by mixing equal volumes of 1 M sodium acetate and 1 M acetic acid? (The pK of acetic acid is 4
Solnce55 [7]

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
