Answer: Transition from X to Y will have greater energy difference.
Explanation: For studying the energy difference, we require Planck's equation.
where, h = Planck's Constant
c = Speed of light
E = Energy
= Wavelength of particle
From the equation, it is visible that the energy and wavelength follow inverse relation which means that with low wavelength value, energy will be the highest and vice-versa.
As electron A falls from X-energy level to Y-energy level, it releases blue light which has low wavelength value (around 470 nm) which means that it has high energy.
Similarly, Electron B releases red light when it falls from Y-energy level to Z-energy level, which has high wavelength value (around 700 nm), giving it a low energy value.
Energy Difference between X-energy level and Y-energy level will be more.
.Answer:
a fact about copper Copper has a reddish-metallic coloring unique among all the elements. The only other non-silvery metal on the periodic table is gold, which has a yellowish color. The addition of copper to gold is how red gold or rose gold is made sulfur
.Explanation:
sulfur is an essential element for life. It's found in amino acids (cysteine and methionine) and proteins. Sulfur compounds are why onions make you cry, why asparagus gives urine a weird odor, why garlic has a distinctive aroma, and why rotten eggs smell so horrible Mercury Mercury looks pretty, in its shiny, fast-moving liquid form, but don't touch! It can be extremely poisonous to humans. The symbol Hg that mercury is known by comes from its Greek name, hydrargyrum, which means "liquid silver" — to reflect its shiny surface. The element is also known as quicksilver for its mobility.
i can only fit in this much sorry
I agree with him I also think it is #2 but it's hard to explain, it just makes more sence...
hope this helps!
Answer: since water is denser than the ice, the ice, floats to the top
