Out of the given options, the best example of a solution containting a non-aqueous solvent is paint<span>. Steel is not a liquid solution, it is instead a solid-state solution so it is not considered. Orange juice and shaving cream both rely on water as a solvent. Paint is actually an emulsion, where polymer substances are spread throughout the oil-based solvent in which they are immiscible. The fact that paint thinners are also oil based and paint is unaffected by water also indicate that it uses a nonaqueous solvent.</span>

<span>The answer is paint. A dissoluble is a substance that breaks up a solute in the arrangement of an answer, and any dissoluble other than water is viewed as a non-fluid dissoluble. Some basic illustrations incorporate either, liquor, benzene, disulfide, carbon tetrachloride and CH3)2CO.</span><span />

λmax for the π → π* transition in ethylene is 170 nm. Is the HOMO-LUMO energy difference in ethylene greater than or less than t
-Dominant- [34]

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

What is the difference between Arrhenius acids-base and bronsted-lowry acids bases? Justify your answer.
Oxana [17]

Answer:

A Bronsted-Lowry acid like and Arrhenius acid is a compound that breaks down to give an H+ in solution. The only difference is that the solution does not have to be water. ... An Arrhenius base is a molecule that when dissolved in water will break down to yield an OH- or hydroxide in solution.

PLEASE HELP!! EXPLAIN YOUR ANSWER PLEASE! :)

The formula for force is F=ma. Because weight is a measure of force, then we can substitute the weight of the meteor, 3204 N, for F in the the equation for force. We also know that the acceleration of gravity on Earth is 9.8 m/s^2. To find the mass, simply divide both sides of the equation by the value of acceleration to get
m =   \frac{f}{a}  =  \frac{3204}{9.8}  = 326.9
Therefore, the value of the mass of the meteor is 326.9 kg.

Explain how temperature and precipitation are affected by latitude and the sun's rays.
Contact [7]
Latitude and Temperature

At the equator, the Sun's rays are most direct. This is where temperatures are highest. At higher latitudes, the Sun's rays are less direct. The farther an area is from the equator, the lower its temperature.
