Answer:
We have the final answer as
Explanation:
To find the energy of a photon of this light we use the formula
<h3>E = hf</h3>
where
E is the energy
f is the frequency
h is the Planck's constant which is
6.626 × 10-³⁴ Js
From the question
f = 7.08×10¹⁴ Hz
We have
E = 7.08×10¹⁴ × 6.626 × 10-³⁴
We have the final answer as
Hope this helps you
Answer:
The correct option is A. The salt is more soluble in water since it can form stronger ion-dipole interactions not available to the fatty acid.
Explanation:
An ion-dipole interaction occurs when an ionic compound is placed in a polar solvent. As salts are ionic compounds and water is a polar solvent, so the fatty acid salts will be able to form electrostatic ion-dipole interactions with the polar water molecules. These interactions will cause fatty acid salts to dissolve in water.
The fatty acid is not an ionic compound and will not form the ion-dipole interactions with the water molecules. Hence, fatty acids will be less soluble in water.
Physical changes are changes that change the physical traits of the substance, without making any change in their internal structure. Chemical changes effect internal structure of the substance and new substance is formed.
Examples of physical changes - breaking glass, evaporating alcohol, shredding paper...
Chemical : burning paper, heating sugar to form caramel, rusting of iron...
