If you performed an experiment with one of these species and painted over the blue patch with red color in male 1 and then placed male 2 (with a normal blue patch) in the same enclosure, what might you expect to see?
Assuming the color is the trigger, the 'normal' male would approach the modified male, thinking it was a female to mate. The modified male would only see a 'trespassing' male,...

The energy of colored light increases in order: red, yellow, green, blue, violet. What are the metallic elements used in the flame test in increasing order of energy of the light emitted?
There are plenty others, but here are some common ones. Correct me if I'm wrong in places.

What is the energy of a photon of red light that has a frequency of $4.48 * 10^14$ Hz?
Use the formula $E=hv$. ${(E="energy of photon"),(h="Planck constant"=6.626xx10^-34),(v="frequency of photon"):}$ We can plug in what we know: $E=(6.626xx10^-34)(4.48xx10^14)$ Plug this into your calculator: $E=2.97xx10^-19$ $"J"$...

What is the wavelength of a photon of red light (in nm) whose frequency is $4.55*10^14$ $Hz$?
$lambda$ = $c/f$ $lambda = $wavelength (m) $c=$ speed of light $= 3.00 xx 10^8$(m/s) $f =$ frequency of light ($H_z$) $= (3.00 xx 10^8)/(4.55 xx 10^14)$ $ lambda$...

A stationary $He^+$ ion emitted a photon corresponding to a first line of the Lyman series. The photon liberated a photoelectron from a stationary H atom in the ground state. What is the velocity of the photoelectron?
The first line Lyman series is between $n = 1$ and $n = 2$. We know that $"He"^(+)$ is isoelectronic with $"H"$ atom, and thus, we can utilize the Rydberg...

An electron in a mercury atom jumps from level $a$ to level $g$ by absorbing a single photon. How do you determine the energy of the photon in joules?
Relativistic effects are present here... but I assume that the transition from level $a$ to level $g$: has $DeltaL = pm 1$ (the total change in angular momentum is...

A blue solid is changed into a white substance and a colorless gas. Was the blue solid an element or a compound? Explain your reasoning.?
........and we further know that the blue solid was a compound and NOT an element. The blue substance evolved (i) a gas, and (ii) a new white substance. Given the...

What are the results of collisions between faster-moving particles and slower-moving particles?
The faster-moving particles have higher kinetic energy. Energy flows from high to low, thus uniformizing the energy distribution amongst the particles. So, the slower-moving particles end up moving a bit...

Which particles are moving faster, the particles in a mug of hot cocoa or the particles in a glass of cold chocolate milk?
Heat is literally the kinetic motion measurement of a substance. The hotter it is, more and more kinetic and vibrational energy are present.

Which gas effuses faster: hydrogen or chlorine? How much faster?
Graham's law of effusion states that the rates of effusion of two different gases vary INVERSELY as the SQUARE roots of the mass of their particles. $color(blue)(bar(ul(|color(white)(a/a)"Rate"_2/"Rate"_1= sqrt(M_1/M_2)color(white)(a/a)|)))" "$...
