Answer:
1. directly
2. inversely
Explanation:
The relationship between the energy of a photon and its frequency is dictated by another simple equation:
E = hv = hc/λ
where E is the energy in kiloJoules per mole, h is Planck's constant with a value of 6.626 x 10-34 Joule-seconds per particle, λ is the wavelength of light λ in meters, and c is the speed of light with a constant value of 300 million meters per second. From this equation, it is clear that the energy of a photon is directly proportional to its frequency and inversely proportional to its wavelength. Thus as frequency increases (with a corresponding decrease in wavelength), the photon energy increases and vice versa.

No. Chemical compounds are seldom similar to the elements they're made of.
Here is another example to think about:
<em><u>Sodium</u> . . .</em>
a soft, silvery-white, highly reactive metal;
If exposed to air, the surface rapidly tarnishes and turns dark.
It reacts with water, to the point that a large piece in water may explode.
<em><u>Chlorine</u></em> . . .
a pale yellow-green gas at room temperature;
a strong bleach and disinfectant;
in the upper atmosphere, responsible for ozone depletion;
extremely dangerous and poisonous for all living organisms;
used in World War I as the first chemical warfare agent;
<em><u>Chemical compound of sodium and chlorine</u> . . .
</em>not a highly reactive metal
does not tarnish and turn dark when exposed to air
does not explode in water
not pale yellow-green<em>
</em>not a gas at room temperature
not useful for bleach or disinfectant
not responsible for ozone depletion
not dangerous or poisonous for living organisms
never used as a chemical warfare agent
chemical name: "sodium chloride"
common name: "salt"
widely used in cooking and eating, to season food
Answer:
D . goggles, a lab coat, heat-proof gloves, and close-toed shoes
Explanation:
Answer:
KE = 1/2mv^2
KE = 1/2(1120)(40^2)
KE = 560(1600)
KE = 896000
