Answer:
C. A conductor that has less conductivity than do metallic
conductors
Explanation:
Semi means less
Answer:
60.57g of TRIS did you use
Explanation:
The concentration of the Tris solution buffer is 0.5 molar (That is, 0.5 moles per liter). As you need to make 1L, you need to have in the solution <em>0.5 moles of TRIS.</em>
<em />
To convert these moles of TRIS to grams you need to use the molecular weight of TRIS base (121.14g/mol), thus:
0.5 moles TRIS * (121.14g / mol) =

<u>Step 1: Define</u>
[RxN] 2Na + Cl₂ → 2NaCl
[Given] 34.485 g Na
<u>Step 2: Identify Conversions</u>
[RxN] 2 mol Na = 1 mol Cl₂
Molar Mass of Na - 22.99 g/mol
<u>Step 3: Stoichiometry</u>
- Set up:

- Multiply/Divide:

<u>Step 4: Check</u>
<em>Follow sig fig rules and round. We are given 5 sig figs.</em>
Since our final answer has 2 sig figs, there is no need to round.
