A student performs a magic trick for their science classroom. They place clear Orbeezes inside a glass of water and the Orbeezes

seem to disappear. The student then pours out the water to reveal that the Orbeez are still inside the glass. What property of waves allows for this illusion to be successful?

Answer:

First off, these balls are, as implied by their name, made of a polymer

Explanation:

—a material with a repeating molecular structure (like plastic or even DNA)—that does a super good job of absorbing water.

Physical reactions of carbonyl group​
docker41 [41]

Answer:

The polarity of the carbonyl group notably affects the physical properties of melting point and boiling point, solubility, and dipole moment. Hydrocarbons, compounds consisting of only the elements hydrogen and carbon, are essentially nonpolar and thus have low melting and boiling points.

In the reaction, 3Cu + 2Al3+ → 3Cu2+ + 2Al, which substance is being oxidized?
Wittaler [7]
In this reaction, Copper is the element being oxidized because it is losing electrons. It starts with a neutral charge (0) and ends up with a 6+ charge. Because its charge is increasing, it is being oxidized (losing electrons).

The work function of an element is the energy required to remove an electron from the surface of the solid. The work function fo
uranmaximum [27]

Answer:

λ = 2.38 × 10^(-7) m

Explanation:

We are given the work function for palladium as 503.7 kJ/mol.

Now let's convert this to KJ/electron.

We know from avogadro's number that;

1 mole of electron = 6.022 × 10^(23) electrons

Thus,

503.7 kJ/mol = 503.7 × 1/(6.022 × 10^(23)) = 8.364 × 10^(-22) KJ/electron = 8.364 × 10^(-19) J/electron

Formula for energy of a photon is;

E = hv

Where;

h is Planck's constant = 6.626 × 10^(-34) J.s

v is velocity

Now, v = c/λ

Where;

c is speed of light = 3 × 10^(8) m/s

λ is wavelength of light.

Thus;

E = hc/λ

Making λ the subject, we have;

λ = hc/E

λ = (6.626 × 10^(-34) × 3 × 10^(8))/(8.364 × 10^(-19))

λ = 2.38 × 10^(-7) m
