Answer:
A solution that is 0.10 M HC2H3O2 and 0.10 M LiC2H3O2 is a good buffer system.
Explanation:
A buffer is defined as the mixture between a weak acid and its conjugate base or vice versa.
For the solutions:
0.10 M HF and 0.10 M LiC2H3O2. HF is a weak acid but LiC2H3O2 is the conjugate base of the weak acid (HC2H3O2, acetic acid).
0.10 M HC2H3O2 and 0.10 M LiC2H3O2. Here, you have a mixture of HC2H3O2, acetic acid, weak acid, and LiC2H3O2 is its conjugate base. Thus, <em>this is a good buffer system</em>
<em></em>
0.10 M LiOH and 0.10 M KOH. LiOH ans KOH are both strong bases.
0.10 M HF and 0.10 M NH4+. Again, HF is a weak acid but NH4+ is the conjugate acid of a weak base (NH3).
Answer:
Error in measure= 1.55-1.32= 0.23
Orville's % error = 0.23/1.32*100% = 17.42%
Explanation:
Answer:
Anything that shares electrons.
Explanation: This means they don't transfer electrons.
Na is the elemental abbreviation for sodium, and Cl is the abbreviation for chlorine.
When the two are combined, you get sodium-chloride, or table salt.
Hope that helped =)
