Difference in density between the two liquids
It is a chemical <em>process</em> - an oxidation.
Table salt has the formula NaCl, where Na is sodium and Cl is chlorine. It is an ionic compound which consists of the cation Na⁺ and the anion Cl⁻. The positive charge in Na means that it readily donates one electron to another. Hence, the proton is transferred from sodium to chlorine.
Answer:
the HOMO-LUMO energy difference in ethylene is greater than that of cis,trans−1,3−cyclooctadiene
Explanation:
The λmax is the wavelength of maximum absorption. We could use it to calculate the HOMO-LUMO energy difference as follows:
For ethylene
E= hc/λ= 6.63×10^-34×3×10^8/170×10^-9= 1.17×10^-18J
For cis,trans−1,3−cyclooctadiene
E= hc/λ=6.63×10^-34×3×10^8/230×10^-9=8.6×10^-19J
Therefore, the HOMO-LUMO energy difference in ethylene is greater than that of cis,trans−1,3−cyclooctadiene
D.) It depends cuz no yeild is 100%..I mean side reactions also occur in most of the reactions. So mass of the reactant is not equal to the mass of the product. Hope it helps
