The external force is the impact by which an outer object has in contact with the object being described. The force that is stronger prevails in that collision. </span><span>Physical properties are those which can be measured or observed without altering the composition of matter.</span>
Breaking an egg is an example of a physical change. This is because the egg was broken, thus its physical appearance was different. If you were to cook the egg, that would be a chemical change because that would result in a new chemical formation of the stuff inside of the egg. But since you're only breaking the egg, it's just a physical change.
I guess that answers both questions.
Hope that helped!
Answer:
3.65 g of cyclohexene
Explanation:
Cyclohexanol + phosphoric acid ----> cyclohexene
The reaction is 1:1 hence the limiting reactant is phosphoric acid.
Hence,
1 mole of phosphoric acid yields 1 mole of cyclohexene
0.0444 moles of phosphoric acid yields 0.0444 moles of cyclohexene
Theoretical yield = number of moles of cyclohexene × molar mass of cyclohexene
Theoretical yield = 0.0444 moles of cyclohexene × 82.143 g/mol
Theoretical yield = 3.65 g of cyclohexene
For waves velocity (v) is equal to the wavelength (λ) times frequency (f). (They are inversely proportional)
V=λf
Since V is constant, if frequency increases, wavelength decreases.
