Which molecule will undergo only London dispersion forces when interacting with other molecules of the same kind? a.HCl b.C2H5OH c.NH3 d.CH4
Answer:
CH4
Explanation:
London dispersion forces are a type of force acting between atoms and molecules that are normally electrically symmetric; that is, the electrons are symmetrically distributed with respect to the nucleus. They are part of the van der Waals forces(Wikipedia). It is a temporary attractive force that results when the electrons in two adjacent atoms occupy positions that make the atoms form temporary dipoles. This force is sometimes called an induced dipole-induced dipole attraction(Chem Purdue).
If we consider HCl, C2H5OH and NH3, we will discover that they all have polar bonds. Consequently, dipole - dipole interaction as well as hydrogen bonds exist between their molecules.
CH4 is nonpolar. Being a nonpolar molecule, the only possible intermolecular interaction forces between its molecules is the London dispersion forces.

Please answer the following questions:
Why does Na have only one dot?
Why do none of these diagrams show more than 8 dots?
What relationship do you notice between the dots in these two charts?
The number of dots that hydrogen and helium have in their dot diagram is the same as the number of electrons shown for them on the Periodic Table. Why? (Hint: Octet Rule (Links to an external site.))
Hello! Here's the answer I was able to come up with:
Why does Na have only one dot?
Sodium, or Na, has only one valence electron. (This makes the atom tend to participate in ionic bonding and "give" its single valence electron to an atom like chlorine.)
Why do none of these diagrams show more than 8 dots?
It is physically impossible for an atom to have more than 8 electrons in its valence layer, according to the Octet Rule.
What relationship do you notice between the dots in these two charts?
The dot diagram for each element represents the number of electrons each element will have in its outermost, or valence, shell. (2-8-8)
The number of dots that hydrogen and helium have in their dot diagram is the same as the number of electrons shown for them on the Periodic Table. Why?
An atom can have a maximum of two electrons in its innermost layer. Hydrogen and helium have only one and two electrons, respectively, so they don't have enough electrons to actually have more than one layer. Therefore, their outermost layer is, in fact, their only layer. This is why the number of dots that hydrogen and helium have in their dot diagram is the same as the number of electrons shown for them on the Periodic Table.

Answer: The amount of water produced is 9.3 grams
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
[tex]CH_4+2O_2\rightarrow CO_2+2H_2O[/tex]
mass of reactants = mass of methane + mass of oxygen = 22.5 g + 35.7 g = 58.2 g
mass of products = mass of carbon dioxide + mass of water = 48.9 g + mass of water
48.9 g + mass of water = 58.2 g
mass of water = 9.3 g
Consider the reaction H2(g) + I2(g) Double headed arrow. HI(g) with an equilibrium constant of 46.3 and a reaction quotient of 525. Which direction will the system shift to?
Answer:
The reaction shifts to the left.
Explanation:
Equilibrium constant (K) = 46.3
Reaction Quotient (Q) = 525
The relationship between Q and K with their implications are given as;
K = Q (No net reaction)
K > Q (Reaction shifts to the right)
K < Q (Reaction shifts to the left)
Since in this question, Q (525) > K (46.3)
The reaction shifts to the left.

PLEASE HELP I WILL MARK YOU BRAINLIEST How many moles of FeCl2 do you need to react 5 moles of Cl2?
Answer:
1. Ok, so you have a 1:1 ratio of FeCl2 to FeCl3, which is shown by the fact that if you react 2 moles of FeCl2 you get 2 moles of FeCl3. So therefore, if you react 4 moles of FeCl2, you'd form 4 moles of FeCl3.
2. You have a 1:2 ratio of Cl2 to FeCl2, for every 1 mole of Cl2, you need 2 moles of FeCl2, so therefore, for 7 moles of Cl2, you need 2x7moles = 14 moles
3. 1:1 ratio. So you start with 2.28moles.
4. 1:2 ratio of Cl2 to FeCl2, so therefore to get from FeCl2 to Cl2 you need to divide by 2. Therefore, you need 3.25moles / 2 = 1.625 moles

please help from the first to last question?
Answer:
The hypothesis is that you are going to have lots of energy due to \you having the energy drink! so it would be "A" for the first question. For the 2nd question i would have to guess "B"! :) Number 3 wouldn't be "C" because it is a specified the theory, so it might be "A"! Number 4 would be "B" cause you do controlled experiments to prove your hypothesis to make a theory! Hypothesis are built off certain beliefs our guesses you think would happen so I believe it would be "D". Hopefully this helped and have a wonderful day!!
You have two wires made of two different metals (metal A and metal B). Both wires are the same thickness and length. In one circuit, you use the metal A wire. In another identical circuit, you use the metal B wire. The metal A wire gets hot, while the metal B wire does not. Explain
Answer:
because metal A is not suitable for electric connection and metal B is suitable
A metallic wire is a cylindrical and flexible wire that carries electricity. Metal A wire gets hot as it is not suitable to conduct electricity.
What is a conductor?A conductor is a substance that can carry or pass the electricity and heat through it. The thickness and the length of the wire play a role in resistivity.
The metallic wire with good conductivity passes the electricity easily through it, while bad conductivity results in the release of heat through the wires making them lose energy.
Therefore, metal A wire gets hot.

2A → B + C The above reaction is run and it is found that a plot of the natural log of the concentration versus time is linear. This indicates that the reaction is ...
Answer:
zero order reaction
Explanation:
The seem to be a reaction is zero order as the data only fits to zero order integrated rate law.
Integrated rate law:
[A] = [A]_0 – kt
Here y = [ A] and slope is -k , so when we plot concentration of A with respect to t then we get the equation in the form of line
y = mx + c
So the answer Zero order in [A]
