Answer:
b. changing the compound changes the absorbance behavior.
Explanation:
- Option a) would be akin to modifying the <em>path length</em>, b.
- Option b) would involve using a different solute, as such, there would be another <em>molar absortivity</em>, ε.
- Option c) would decrease the<em> concentration</em> (c) of the solute, which would explain why the absorbance would decrease as well.
After ionization, sodium gains a net positive charge cuz sodium loses its 1 valence electron to gain the nearest stable octet which is neon{Ne}. Hope it helps
Answer:
5.46 8 x 10²³ molecules.
Explanation:
- <em>Knowing that every one mole of a substance contains Avogadro's no. of molecules (NA = 6.022 x 10²³).</em>
<em><u>Using cross multiplication:</u></em>
1.0 mole → 6.022 x 10²³ molecules.
9.08 x 10⁻¹ mole → ??? molecules.
∴ The no. of molecules of CO₂ are in 9.08 x 10⁻¹ mol = (6.022 x 10²³ molecules) ( 9.08 x 10⁻¹ mole) / (1.0 mol) = 5.46 8 x 10²³ molecules.
