For visible light, explain how wavelength and energy vary for the different colors. Provide the trends in wavelength for the spectrum of light (purple to blue to green to yellow to orange to red). How is this different for energy?
Answers
Answer:
See explanation
Explanation:
If you look closely at the image attached, you will discover that the order of increasing wavelength in the visible spectrum is;
violet < indigo< blue < green < yellow < orange < red
On the order hand, the energy of the photons increases in the order;
Red < orange < yellow < green < blue < indigo < violet
Since energy follows a trend opposite to that of wavelength, we can see that the greater the wavelength of light, the lower the energy of photon corresponding to that particular colour.

how are water and salt regulated at the organ level
Answers
Hope this helped! :D
Salt and water level is balanced in our body by the proper regulation through hormonal actions. The level of sodium is controlled and the water if needed is reabsorbed from urine. And if the salt concentration is higher it is removed through urine.
What water- salt balance ?In addition to actively holding or releasing water in urine, the body manages its salt and water balance by excreting extra sodium in urine. This method has the benefit of reducing the need on external water sources for the long-term preservation of bodily fluids.
Researchers discovered that the kidney regulates levels of sodium, potassium, and the waste product urea to save or release water. This may be the link between salt consumption and glucocorticoid levels.
A high-salt meal raised glucocorticoid levels, which increased the amount of energy utilized by the liver and muscle to generate urea, which the kidney then used to conserve water.
The maintenance of the body fluids' normal concentration, or the sum of all dissolved chemicals that would exert osmotic pressure against a barrier impervious to them, is known as osmotic control.

How does the average reaction rate differ from an instantaneous reaction rate?
a) The average reaction rate is how quickly the reaction proceeds at a specific time. An instantaneous reaction rate is how quickly the reaction proceeds over time.
b) The average reaction rate is how quickly the reaction proceeds over time considering the reactants. An instantaneous reaction rate is how quickly the reaction proceeds at a specific time considering the products.
c) The average reaction rate is how quickly the reaction proceeds over time. An instantaneous reaction rate is how quickly the reaction proceeds at a specific time.
d) The average reaction rate is how quickly the reaction proceeds over time. An instantaneous reaction rate is how quickly the reaction proceeds compared to another reaction.
Answers
Answer:1. The instantaneous rate is the rate of a reaction at any particular point in time, a period of time that is so short that the concentrations of reactants and products change by a negligible amount. The initial rate is the instantaneous rate of reaction as it starts (as product just begins to form).
Explanation:
average rate
rate of a chemical reaction computed as the ratio of a measured change in amount or concentration of substance to the time interval over which the change occurred
initial rate
instantaneous rate of a chemical reaction at t = 0 s (immediately after the reaction has begun)
instantaneous rate
rate of a chemical reaction at any instant in time, determined by the slope of the line tangential to a graph of concentration as a function of time
rate of reaction
measure of the speed at which a chemical reaction takes place
rate expression
mathematical representation relating reaction rate to changes in amount, concentration, or pressure of reactant or product species per unit time

1. State the relationship between atomic radius and metallic reactivity down group 2. Explain in terms of atomic structure why this relationship occurs. as atomic radius down group 2
Answers
Answer:
Atomic radius is directly proportional to Metallic reactivity in group 2.
Explanation:
Atomic radius is directly proportional to Metallic reactivity in group 2.
As we move down the group in group 2 which is called as the alkaline earth metals, the atomic number increases due to which the subshell increases. And the outermost shell's electron are less tightly held to the nucleus of the atom. Since the electrons are loosely held that means they can easily participate in reactions and that what makes it reactive down the 2nd group. Therefore alkaline earth metals with higher atomic number are more chemically reactive.

What is reflection of light ?Reflection of light refers to the bouncing back of light rays when they hit a surface, such as a mirror or any other smooth, shiny object. When light strikes a surface, some of it is absorbed by the surface, some of it is transmitted through the surface, and some of it is reflected.
The angle at which the light strikes the surface, known as the angle of incidence, determines the angle at which the light is reflected, known as the angle of reflection.
When light hits an object, some of the energy is absorbed by the object and some of it is reflected. Darker colors absorb more energy from the light, while lighter colors reflect more of the energy away.
Therefore, a black T-shirt absorbs more energy from the Sun's rays, making it warmer than a white T-shirt which reflects more of the energy away.

Answers
Answer:
Explanation:
2C₂H₂ + 5O₂ = 4CO₂ + 2H₂O .
CO₂ formed in moles = 33.4 / 44 = .76 moles
4 moles of CO₂ is formed by 2 moles of C₂H₂
.76 moles of CO₂ is formed by .38 moles of C₂H₂
.38 moles of C₂H₂ were present initially
2 moles of C₂H₂ produces 2 moles of water
.38 moles of C₂H₂ produces .38 moles of water
water produced = .38 moles
= .38 x 18 = 6.84 grams of water .

atom 1 has mass=12 protons=6
atom 2 has mass=14 electrons=6
are these atoms isotopes of each other or different elements
Answers
Answer:
Atom isotopes
Explanation:
The number of protons is equal to the number of electrons in elements therefore atom 2 has 6 protons like atom 1. This means that both are the same atom but with different masses which means they are isotopes.
The atoms are isotopes.
Isotopes are atoms having the same atomic number (i.e proton) but different mass number due to the difference in the neutron number of the atoms involved.
For atom 1:Mass number = 12
Proton = 6
For atom 2:Mass number = 14
Proton = Electron = 6 (for neutrao atom)
From the above, we can see that atom 1 and atom 2 have the same number of protons but different mass number.
Therefore, we can conclude that the atoms are isotopes

Name three ways in which unicellular organisms can move. Describe one of them.
Answers
Answer:
Unicellular organisms achieve locomotion using cilia and flagella. By creating currents in the surrounding environment, cilia and flagella can move the cell in one direction or another.
Explanation:
Unicellular organisms are the smallest and simplest of all living beings, they are composed of a single cell, and they do not form any type of tissue.
They move through appendages of the membrane that allow movement which are:
Flagella, these are long and thin appendages that serve as locomotion organelles and are responsible for the majority of mobile bacteria being able to move in liquid media. Cilia are mobile extensions of the plasma membrane that cover the surface of its membrane and have the function of facilitating metabolism by producing movements and currents in the liquid of the cellular environment.Pseudopods are extensions of the protoplasm area used in a similar way to cilia and flagella.Amoebas, unicellular protists, are characterized by their irregular shape and their movements based on pseudopods, that is, tentacular extensions of their cytoplasm that allow them to engulf (engulf) food and incorporate them through their cell membrane.
Therefore, we can conclude that the 3 ways unicellular organisms can move are through fragelli, cilia, and pseudopods.

It implies that things we refer to as "particles," like electrons, in some ways mix the traits of both particles and waves. That is quantum physics' renowned wave-particle duality.
