Explanation:

determine how many grams of kno3 would dissolve in 100g of water at 50 degrees celcuis to make a saturated solution
The amount of KNO₃ would dissolve in 100g of water at 50 degrees celcuis to make a saturated solution is 44 g.
To create a saturated solution of KNO₃ in 100g of water at 50 degrees Celsius, the following steps should be taken:
Step 1: Find out the mass of the solvent in the saturated solution.
The solvent is water in this instance. So, using the formula for the mass of a solution, we can calculate the mass of the solvent in the saturated solution as follows:
Mass of solvent = Mass of solution - Mass of solute
= 100 g - Mass of KNO₃
Step 2: Determine the amount of solute that would be dissolved in the solution to make it saturated.
The mass of KNO₃ that would dissolve in 100 g of water at 50°C to create a saturated solution is 56g/100g of water.
Step 3: Calculate the mass of KNO₃ that would dissolve in 100g of water to make a saturated solution.
Mass of KNO₃ = Solubility of KNO₃ × Mass of solvent
Mass of KNO₃ = 56 g/100 g × (100 g - Mass of KNO₃)
Now, let's solve for Mass of KNO₃;
56 = 56g(100-Mass of KNO₃)/100100 - Mass of KNO₃ = 100
Multiply both sides of the equation by 100 to obtain;
5600 - 100 Mass of KNO₃ = 100
Mass of KNO₃ = 5600/10100 - 56
= 44 g
Therefore, 44 g of KNO₃ would dissolve in 100g of water to make a saturated solution.

For which properties can a student design an investigation of the electrostatic forces between molecules in a substance?.
Intermolecular forces such as dipole-dipole forces, London dispersion forces exist between molecules and these depend on strength of electronegativity of molecule. For knowing melting point, boiling point, surface tension, and vapor pressure properties, student design an investigation of the electrostatic forces between molecules in a substance.
What is intermolecular forces of attraction?Intermolecular forces of attraction is force of attraction that make two molecule come closer. Intermolecular forces of attraction is directly proportional to the electronegativity of the molecule.
Size of electronegative molecule is small so, if any other molecule or molecule come into contact with this molecule then this molecule attract the electron of other molecule very efficiently and therefore the force between the molecule increases. Electrostatic forces between molecules in a substance helps in knowing melting point, boiling point, surface tension, and vapor pressure properties

Answer:
Moths are hunted and killed in a variety of ways. I'll explain how we go about hunting and killing moths.
Explanation:
Step-by-Step:
Obtain a sticky trap in the morning and afternoon. It's available at Target and Walmart. Cover it in moth pheromones or anything else you know will attract moths. They will be stuck in the sticky trap for a long time and will eventually die as a result of not being able to escape.
At night, get or buy a lamp and turn it on. This will attract a lot of moths and make them easier to see. Then spray the area with insecticide or insect repellent. Finally, they should perish.

There are 6 σ bonds and 3 π bonds in H₃C-CH₂-CH═CH-CH₂-C≡CH.
In the given chemical structure, σ (sigma) bonds are formed by the overlap of atomic orbitals in a head-to-head fashion. These bonds allow for the sharing of electrons between the atoms involved. Each single bond, whether between carbon and hydrogen or carbon and carbon, is a σ bond. Therefore, we count the number of single bonds to determine the number of σ bonds.
In this molecule, there are six single bonds: three between carbon and hydrogen and three between carbon and carbon.Hence, there are 6 σ bonds in total.
In the given structure, there are three double bonds: one between carbon atoms (═), one between carbon and carbon (ch═ch), and one between carbon and carbon (c≡ch). Each double bond consists of one σ bond and one π bond.

How do you find the mass in grams of one formula unit of a compound given all the atomic masses of every element in the compound?
Answer:
Explanation:
The atomic mass of an element is the average mass of the atoms of an element measured in atomic mass unit (amu, also known as daltons, D). The atomic mass is a weighted average of all of the isotopes of that element, in which the mass of each isotope is multiplied by the abundance of that particular isotope. (Atomic mass is also referred to as atomic weight, but the term "mass" is more accurate.)
Answer:
The characteristic molar mass of an element is simply the atomic mass in g/mol. However, molar mass can also be calculated by multiplying the atomic mass in amu by the molar mass constant (1 g/mol). To calculate the molar mass of a compound with multiple atoms, sum all the atomic mass of the constituent atoms.

In three to five sentences describe the mistake the student made and determine whether or not the reaction is a redox reaction. explain your answer (4 points)
A redox reaction is when there is simultaneous oxidation and reduction. CuO+H2→Cu+H2O. Example: In this reaction, hydrogen is oxidised to water while copper oxide is reduced to copper.
By assuming that all bindings to the atoms in molecules are ionic, we can use the oxidation numbers assigned to atoms in molecules to detect redox reactions. In a reaction, oxidation is shown by an increase in the number of oxidations, and reduction is indicated by a copper. Consider the sodium-water reaction. In this reaction, sodium removes hydrogen from water while both becoming oxidised by obtaining oxygen and reducing the water to hydrogen by removing oxygen at the same time.

The nuclear fission is the process in which the atoms nucleus splits into two or more smaller nuclei. The nuclear fission produces the large amount of the energy. It does not occurs naturally. The nuclei generates through the fission power plant is unstable. This is the disadvantage of the nuclear fission. The process of the fission produces the gamma photons and releases the large amount of energy as compared to the nuclear fusion.

a tghin layer of oiol floats on a puddle of water. what is the minimum thickness of the oil needed to completely reflect blue light
The minimum thickness of the oil needed to completely reflect blue light is approximately 160 nanometers.
It's important to provide a concise answer, so I'll keep my response brief and focused on the essential information.
To find the minimum thickness of the oil needed to completely reflect blue light, we can use the thin-film interference formula:
t = (mλ) / (2n)
where:
- t is the thickness of the oil layer
- m is the order of interference (minimum m = 1 for complete reflection)
- λ is the wavelength of the blue light
- n is the refractive index of the oil
Blue light has a wavelength of approximately 450 nm (nanometers). The refractive index of oil depends on the specific type, but it generally ranges from 1.4 to 1.5.
Using the formula and assuming the minimum order of interference (m = 1) and the lower end of the refractive index range (n = 1.4), we can calculate the minimum thickness of the oil layer:
t = (1 * 450 nm) / (2 * 1.4)
t ≈ 160 nm
Therefore, the minimum thickness of the oil needed to completely reflect blue light is approximately 160 nanometers.
