copper(ii) ions appear blue in aqueous solution. this is the transmitted color. the wavelengths of light that are not absorbed give rise to the perceived or transmitted color of a substance. based on the principle of complementary colors, which colors and wavelengths would you expect to be the most strongly absorbed by cu 2 ions?
Based on the Principle of Complementary Colors , the colors and wavelengths expected to be the most strongly absorbed by cu 2+ ions are :-
Orange : 600–640 nm
Blue : 450–480 nm
Violet :400–450 nm
Green : 450–560 nm
Red : 640–700 nm
Yellow : 560–600 nm
Complementary color are pairs of colors which, while blended or mixed, cancel every different out (lose hue) via generating a grayscale color like white or black. whilst located next to every other, they devise the most powerful contrast for those colours. Complementary colours may also be known as "opposite colorings".
The RGB coloration version, invented inside the 19th century and absolutely advanced inside the twentieth century, uses combos of pink, inexperienced, and blue mild towards a black heritage to make the colours visible on a computer monitor or television display. Within the RGB version, the primary colors are purple, green, and blue. The complementary number one–secondary combinations are crimson–cyan, inexperienced–magenta, and blue–yellow. Inside the RGB colour version, the mild of complementary shades, consisting of pink and cyan, combined at full depth, will make white mild, for the reason that complementary hues comprise mild with the whole variety of the spectrum. If the light isn't always completely severe, the resulting mild will be gray.

diazomethane is a highly poisonous, explosive compound because it readily evolves n2. diazomethane has the following composition by mass: 28.57% c; 4.80% h; and 66.64% n. the molar mass of diazomethane is 42.04 g>mol. find the molecular formula of diazomethane, draw its lewis structure, and assign formal charges to each atom. why is diazomethane not very stable? explain.
The molecular formula of diazomethane is CH₂N₂, and the main reason for its instability is precisely the fact that it can very easily evolve nitrogen, as nitrogen's triple bond is one of the strongest covalent bonds in nature, and the energy released in its formation is more than enough to compensate the energy lost in the breaking of C-N bonds. The Lewis structure of diazomethane with the formal charges is attached below.
To obtain the molecular formula of diazomethane, we can imagine that we have 100 g of it. Now we can calculate the number of moles (n) for each of the elements, using their respective masses (m) and molar masses (M = 12 g/mol for carbon, 1 g/mol for hydrogen, and 14 g/mol for nitrogen):
n = m/M
n(C) = 28.57 g / 12 g/mol
n(C) = 2.38 mol
n(H) = 4.80 g / 1 g/mol
n(H) = 4.80 mol
n(N) = 66.64 g / 14 g/mol
n(N) = 4.76 mol
We now divide each of these numbers with the smallest of them (2.38) to calculate the molar ratio of the elements:
carbon: 2.38 / 2.38 = 1
hydrogen: 4.80 / 2.38 = 2
nitrogen: 4.76 / 2.38 = 2
Now we use these numbers to get the empirical formula of diazomethane: CH₂N₂.
The molar mass of the empirical formula is:
12 g/mol + 2 * 1 g/mol + 2 * 14 g/mol = 42 g/mol
Since this value is equal to the molar mass given to us, that means that CH₂N₂ is also the molecular formula of diazomethane.

avogadro's law states that under constant temperature and pressure, the volume of a gas is directly proportional to the number of moles of gas. what is the relationship consistent with this statement?
According to Avogadro`s law, the volume of gas is directly proportional to number of moles of gas.
This law mathematically can be written as:
V ∝ n
V = K n
V/n = K
Where V represents the volume of gas
n represents the number of moles of gas
k is proportionality constant at a given temperature and pressure
This law explains that how equal volumes of all gases contain the same number of molecules when the temperature and pressure are the same. Similarly, this law can be used to compare the same substances under two different sets of circumstances.
V₁ / n₁ = V₂ / n₂
This equation shows that the volume of the gas increases proportionally to the amount of number of moles of gas. Similarly, if the amount of gas decreases result in decrease in number of moles. As a result, neither the size of the molecules nor the molar mass of the gas affects how many atoms or molecules there are in a given volume of an ideal gas.

when aluminum, al , metal is dipped in an aqueous solution of hydrochloric acid, hcl , hydrogen gas, h2 , is produced with the formation of an aluminum chloride, alcl3 , solution. write the balanced chemical equation showing the phases of reactants and products. express your answer as a chemical equation including phases.
The balanced reaction equation for this transformation looks like this:
2Al(s) + 6HCl(aq) → 2AlCl₃(aq) + 3H₂(g)
In order to write the balanced reaction equation for this redox reaction, we must first write what we know. Aluminum metal is solid (Al(s)), and it is reacting with aqueous hydrochloric acid (HCl(aq)). When elemental metals react with acids, this results in the formation of appropriate salts (in this case aluminum chloride, that will be dissolved in water, so AlCl₃(aq)) and elemental gaseous hydrogen (H₂(g)):
Al(s) + HCl(aq) → AlCl₃(aq) + H₂(g)
This reaction equation isn't balanced because we have different numbers of atoms for every element on the left and the right side (except for Al). The easiest way to begin balancing is to notice that chlorine atoms will be balanced if we add 3 in front of HCl:
Al(s) + 3HCl(aq) → AlCl₃(aq) + H₂(g)
However, we can see now that 3HCl cannot possibly produce the H₂ molecule. The smallest common multiple of 3 and 2 is 6, so we should have 6 hydrogen atoms on each side:
Al(s) + 6HCl(aq) → AlCl₃(aq) + 3H₂(g)
To balance the chlorine atoms we add 2 in front of AlCl₃, and then 2 in front of Al to balance aluminum, arriving at the balanced reaction equation:
2Al(s) + 6HCl(aq) → 2AlCl₃(aq) + 3H₂(g)

Definition of atomic massThe atomic mass (A) is obtained by adding the number of protons and neutrons in a given nucleus of a chemical element.
Definition of isotopeThe same chemical element can have the same atomic numbers, but the number of neutrons is different. These atoms are called isotopes of the element.
Definition of atomic massThe atomic mass of an element is the weighted average mass of its natural isotopes, taking into account the relative abundance of each of them.
Atomic mass of the element in this caseIn this case, you know:
The first isotope has an atomic mass of 62.939598 amu and a percent natural abundance of x%. The second isotope has an atomic mass of 64.927793 amu and a percent natural abundance of (100 -x)%.Average mass of copper is 63.54 amu.The percent abundance can be calculated as:
62.939598 amu× (x%÷100%) + 64.927793 amu× [(100-x)%÷100%]= 63.54 amu
Solving:
62.939598 amu× x+ 64.927793 amu× (1-x)= 63.54 amu
62.939598 amu× x+ 64.927793 amu× 1- 64.927793 amu× x= 63.54 amu

waste water treatment often has at least one oxidation-reduction step. in the collection of waste water, chlorine can be added to control corrosion by hydrogen sulfide to give sulfur and chloride ions. what is the balanced equation for the reaction that occurs in this step? include physical states in your answer.
The balanced reaction equation for this redox reaction looks like this:
H₂S(aq) + Cl₂(g) → S(s) + 2HCl(aq)
First, we write what we know about the reaction:
Hydrogen sulfide (H₂S) that is dissolved in the wastewater (so the physical state is (aq)) is reacting with gaseous chlorine (so Cl₂(g)) to form sulfur (which is solid at room temperature, and does not dissolve in water, so S(g)) and chloride ions (Cl⁻). To counter their negative charge, we add the hydrogen from H₂S to chlorides, which results in HCl, which is soluble in water, so the physical state is (aq):
H₂S(aq) + Cl₂(g) → S(s) + HCl(aq)
When we look at this equation we can see that it is not balanced, because we have 2 H atoms and 2 Cl atoms on the left, and only 1 of both on the right. The easiest way to rectify this is to add "2" in front of HCl, resulting in a balanced reaction equation:

this tank has been set up with cold water on one side and warm water on the other. when the divider is removed and the two water samples are allowed to mix, what is most likely to happen?
Since warm water has more energy than cold water, its molecules move more quickly than those in cold water. Gradually both the water will have same temperature according to Principle of calorimetry.
Heat lost by the hot body = heat gained by the cold body
What is principle of calorimetry?
In a calorimeter, two different types of matter are in contact with one another, ideally a liquid and a solid. Both bodies are also at various temperatures. A higher-temperature object can transfer heat energy to a lower-temperature object thanks to this setup.
Heat transfer does not stop, nevertheless, until there is a state of thermal equilibrium between the bodies. The "rule of conservation of energy," which is represented by the principle of calorimetry, states that the total amount of heat absorbed by the cold object and the total amount of heat released by the hot object are equal.
