What kind of intermolecular forces act between two carbon disulfide molecules? Note: If there is more than one type of intermolecular force that acts, be sure to list them all, with a comma between the name of each force.
Two molecules of carbon disulfide are held together by nonpolar intermolecular interactions. The C-S bond is nonpolar because C and S have different electronegativities.
Two bond dipoles in opposite orientations in the linear structure of carbon disulfide balance out the dipole moments. Having the chemical symbol C and atomic number 6, carbon is an element with the meaning "coal" in Latin. It is nonmetallic and tetravalent, meaning that four of its atom's electron molecules can be used to create covalent chemical connections. The periodic table's group 14 is where it belongs. Only 0.025 percent of the crust of the Earth is made up of carbon. The tendency of an atom of a certain chemical element to draw shared electrons (or electron density) when forming a chemical connection is known as electronegativity and is represented by the symbol.

a battery harnesses a chemical reaction to extract energy in the form of useful electrical work. (a) a certain battery runs a toy truck and becomes par- tially discharged. in the process, it performs a total of 117.0 j of work on its immediate surroundings. it also gives off 3.0 j of heat, which the surroundings absorb. no other work or heat is exchanged with the sur- roundings. compute q, w, and du of the battery, making sure each quantity has the proper sign. (b) the same battery is now recharged exactly to its origi- nal condition. this requires 210.0 j of electrical work from an outside generator. determine q for the battery in this process. explain why q has the sign that it does.
The values of ΔU , w and q are -220.0 J, -117.0 J and -3.0 J respectively. As the heat is gained by the system it has a positive sign. Therefore, the value of q is 10.0 J.
A.
Here, battery is the given system. It does work to run the toy truck. Hence work ( w ) is done by the system, therefore, it's sign should be negative.
Battery releases heat to the surrounding, hence, the sign of heat ( q ) is also negative.
Write the mathematical expression for First law of thermodynamics.
ΔU = q + w
Substitute -3 J for q and -117.0 J for w to calculate ΔU of the battery.
ΔU = (-117.0 J)+(-3.0 J)
-220
That means, in this process the internal energy of the system decreases by 220 J.
Therefore, the values of ΔU , w and q are -220.0 J, -117.0 J and -3.0 J respectively.
B.
Now, the battery is recharged to its original condition. As the system has lost 220 J of energy so it
will have to gain 220 J of energy to reach its original condition.
Since, work is done on the battery by an external generator, w will have a positive sign.
Write the mathematical expression for First law of thermodynamics.
ΔU = q + w
Solve for q.
q = ΔU - w
Substitute +220.0 J for ΔU and +210.0 J for w to calculate the value of q.
q = (220.0 J) -(210.0 J)
= 10.0 J
As the heat is gained by the system it has a positive sign. Therefore, the value of q is 10.0 J.

The limiting reactant is the one that is used up first and sets a limit on the quantity of product(s) that can be produced. Calculate the moles of each reactant present and contrast this ratio with the mole ratio of the reactants in the balanced chemical equation to determine the limiting reactant.
When a chemical reaction is complete, the limiting reagent—also known as the limiting reactant or limiting agent—is the reactant that has been completely consumed. Since the reaction cannot proceed without this reagent, the amount of product that can be produced is constrained. Excess reagents or excess reactants are any reagents that are present in amounts greater than those necessary to cause a reaction with the limiting reagent (sometimes abbreviated as "xs"). Since the amount of product produced when the limiting reagent interacts entirely is defined as the theoretical yield, the limiting reagent must be identified in order to calculate the percentage yield of a reaction. There are various equivalent techniques to determine the limiting reagent and assess the excess amounts of other reagents given the balanced chemical equation that describes the reaction.

NaOH + CH3CH2CH2CH2-Cl NaCl + CH3CH2CH2CH2-OH
This is a substitution reaction as opposed to an elimination reaction. One of the primary (1°) alkyl halides, 1-chlorobutane, is "unhindered," and sodium hydroxide's hydroxide ion (OH-) is a potent nucleophile. In this reaction, the hydroxide will take the place of the chloro group to produce solely 1-butanol. The alkyl halide must be sterically inhibited, that is, either tertiary (3°) or secondary (2°), for elimination to take place. However, substitution reactions can also take place for 2° alkyl halides as a rival process, producing a variety of products.
When 1-chlorobutane is present in a sodium hydroxide solution and an E2 elimination takes place, the hydroxide will vigorously deprotonate the 1-chlorobutane. In turn, a double-bond will form and the chlorine group will go as a result. As a result, but-1-ene will be the end result.

Br₂ - nonpolar covalentCsBr - ionicNaCl - ionicCaO - ionicHCl - polar covalentO₂ - nonpolar covalentKF - ionicHBr - polar covalentWhat are diatomic species?Diatomic species are species that are composed of two atoms alone which may be the same or different atoms.
When the two atoms of a diatomic species are of the same element, the species formed is a molecule of the element.
When the two atoms of a diatomic species are of different elements, the species formed is a molecule of a compound.
The nature of the given diatomic species is determined by the atoms present in the diatomic species.
If the atoms have similar electronegativities, a non-polar covalent species are formed.
If the atoms have different electronegativities, polar covalent species or ionic species are formed.

Which of the following is NOT a multivalent ion? A. Au+
B. Ni²+
C. Zn^2+
D. Pb^2+
The Au+ is not a multivalent ion.
What is multivalent ion?
Having more than one valency or having a valency greater than three is referred to as being multivalent (comparatively more multivalent, superlatively most multivalent).
What is ion?
Ions are atoms or groups of atoms that have a different number of electrons than proton atoms. If there are more protons than electrons, the particle is a negative ion, sometimes referred to as a cation.
The all the ions are having the valence electron is 2 so they are considered as multivalent ion, Au+ having one valence electron it is not fall under multivalent ion.
Therefore, Au+ is not a multivalent ion.
