Which of the following is a result of intermolecular forces
Answer:
The three major types of intermolecular interactions are dipole–dipole interactions, London dispersion forces (these two are often referred to collectively as van der Waals forces), and hydrogen bonds
Choose your favorite super hero that gained their powers from radiation. What
type of radiation gave them their powers? Choose a wavelength that falls inside
that spectrum. Calculate energy (SHOW WORK).
Answer:
Copy and paste "Electromagnetic waves are categorized according to their frequency f or, equivalently, according to their wavelength λ = c/f. Visible light has a wavelength range from ~400 nm to ~700 nm. Violet light has a wavelength of ~400 nm, and a frequency of ~7.5*1014 Hz. Red light has a wavelength of ~700 nm, and a frequency of ~4.3*1014 Hz." into google, and the correct website pops up as the first result.
Explanation:
I tried to link the website that I use to convert wavelengths and frequencies into types of light, but it deleted my answer, so I guess we're doing it this way. As for converting the wavelength to energy, the same principles apply as before:
Frequency: ν Wavelength: λ Energy: E Speed of light: C (3.00e8) Planck's Constant: h (6.626e-34)
ν -> λ λ = C/ν
λ -> ν ν = C/λ
For either of these equations, wavelength must be converted to meters or nanometers, depending on the equation.
For ν -> λ, after doing the equation, convert the wavelength into nanometers by dividing by 1e-9.
For converting λ -> ν, convert the wavelength into meters by multiplying by 1e-9.
For energy: E = hν = hc/λ

If you are given 40 grams of a dye that has a molar mass of 200 g/mole and then place it in 2
liters of water, what is the molarity of the resulting solution?
A2M
B 0.1 M
C 1M
D2M
Answer:
B
Explanation:
to find how many moles we have you need to use the molarity equation which for this is
40g * (1mole/200g) = .2 moles
Given we know that we have .2 moles
then all you have to do is divide amount of moles by amount of liters to find the molarity
for this problem it is
.2mol/2L which is .1 M

Explanation:
The exoskeleton of a housefly is made up of
A.keratin. B.chitin. C.lignin. D. All of the above
Answer:
Chitin
Explanation:
A fly's main body is made of a thorax and an abdomen. These parts are covered by a hard exoskeleton made of a bony substance called chitin.
The exoskeleton of a housefly is made up of chitin. Thus, the correct option for this question is B.
What is Exoskeleton?The Exoskeleton may be defined as a tough and rigid external covering present in some invertebrate animals like arthropods. It supports and protects the animals with respect to their external environment.
The main body of a housefly is significantly divided into two regions, i.e. a thorax and an abdomen. The thorax region is further divided into three parts i.e. prothorax, mesothorax, and metathorax.
All these parts of a housefly are remarkably covered by a tough exoskeleton that is constructed of chitin. The housefly has a hard exoskeleton that protects it from moisture loss.
Therefore, the exoskeleton of a housefly is made up of chitin. Thus, the correct option for this question is B.

Explanation:
An irregular object with a mass of 18.00 kg displaces 2.50 L of water when placed in a large overflow container. Calculate the density of the object.
Answer:
7.20 kg/L
Explanation:
Density is mass (kg) / volume (L).
18.00kg/2.50L = 7.20 kg/L
If you need it in g/mL this is the equation:
[tex]\frac{7.20kg}{L} *\frac{1000g}{1kg} *\frac{1L}{1000mL} = 7.20g/mL[/tex]

what is the total charge of 20 electrons in zeka-Coulombs?
Answer:
[tex]3.2\times 10^{-18}\ C[/tex]
Explanation:
No of electrons, n = 20
We need to find the total charge. We can use quantization of electric charge in this case.
Net charge,
q = ne
e is charge on an electron
[tex]q=20\times 1.6\times 10^{-19}\\\\q=3.2\times 10^{-18}\ C[/tex]
So, there are [tex]3.2\times 10^{-18}\ C[/tex] of charge in 20 electrons.
