At this point, helium is exerting 1270 torr of pressure against its container.
What is Boyle's Law?Boyle's Law, a cornerstone of chemistry, describes the behavior of a gas sustained at a constant temperature. Robert A. Boyle discovered this law in 1662: at a certain temperature, the volume of a gas is inversely proportional to the pressure it exerts. To put it another way, if a gas is driven into a closed place, it will condense to fit the area but raise the pressure on the container.
Boyle's law, which is arguably a clearer way to put it, is the relationship between pressure and volume. Mathematically, Boyle's law can be written as pV=k, where p stands for the pressure, volume, and mass of the gas and k is a constant.
The solution is straightforward when temperature and moles are constant,
P₁V₁ = P₂V₂
Given,
P₁ = 760 torr
P₂ = ?
V₁ = 5.00 I
V₂ = 3.00 I
(760)(5.00) = (3.00)(P₂),
P2 = 1270 torr.

What are Ionic compounds ?
Ionic compounds can be defined as ionic bonds or chemical bonds formed by oppositely charged ions held together by electrostatic forces.
These are usually formed between metals and non-metals. Atoms always tend to acquire stable electronic configurations when atoms lose electrons to form cations, and anions are formed when atoms gain electrons. These two oppositely charged atoms together form an ionic bond, which is called an ionic bond.
Ionic compounds, also called ionic compounds, are held together by electrostatic forces. Ionic compounds are also formed when the electronegativity difference between two atoms is large. This causes one atom to attract more electrons than the other, resulting in electron loss and electron gain within the atom.

does a change in temperature affect the solubility of nh3? if yes, at which temperature would nh3 be most soluble? does pressure change has effect on the solubility of nh3? if yes, at which pressure would nh3 be most soluble?
Yes as the temperature increases the solubility of NH3 will decrease and as we increase the pressure solubility of NH3 increases.
Solubility is defined as the maximum amount of substance that will dissolve in a given amount of solvent at a given or specified temperature. Based on solubility different types of solutions can be obtained. A saturated solution is a solution where a saturated solution is a solution where a given amount of solute is completely soluble in the solution.
Whereas a supersaturated solution are those where solute starts precipitating out after a certain concentration.
Temperature does effect the solubility of NH3 because as the temperature increases the hydrogen bonding also decreases, due to which the NH3 molecules are no longer able to bind to water molecules hence their solubility decreases.
But as we increase the pressure on NH3 molecules the bonding with the water molecules will be higher and therefore the solubility also increases.

the expected stoichiometry is 1:1. how does your result compare (calculate the % error between your mole ratio and the expected value)?
Stoichiometry is the representation of balanced chemical equation, that involves the amount or quantities of reactants and products involved in the reaction.
In a chemical equation, stoichiometry is the relation between two or more substances. Stoichiometry can be the definite proportions in which elements or compounds react with one another. The rules followed in calculating the stoichiometric relationships are based on the laws of conservation of mass and energy and the law of combining weights or volumes.
For example:
N2 (g) + 3H2(g) → 2NH3(g)
In the above reaction, Nitrogen (N2) and Hydrogen (H2) react to form Ammonia (NH3).
1 molecule + 3 molecules = 2 molecules

Before the reaction of hydrogen peroxide, if a reagent had changed color immediately after being added to the sample, this would indicate the presence of a contaminant and the test would be invalid.
The above experiment is also knowns as a presumptive blood testing experiment in which if a contaminant is present, the test should be deemed invalid if a vivid blue or purple color appears after adding the TMB reagent but before adding the hydrogen peroxide; this is also frequently referred to as a "false positive" result.
Presumptive tests catalyze the oxidation of a chromogenic substance, which results in a color change, by reacting with the hemoglobin of all blood in humans and animals. If the test is positive, the material will be identified as potentially blood, though not necessarily human blood.

In 1896, Becquerel accidentally discovered radioactivity while observing the phosphorescence of uranium salts, a discovery by Wilhelm Rontgen. X-rays used a cathode-ray tube to produce X-rays. Becquerel wondered whether X-rays could not be produced by exposing ordinary sunlight to non-metallic substances. Coincidentally, Becquerel also discovered for the first time that this new type of radiation would be transmitted by any uranium chemistries. Since the radiation did not depend in any way on the chemical form of the uranium, Becquerel realized that the radioactivity was not of chemical origin, but had to be from the uranium atoms themselves.

Commonly, ions are formed by (i) the loss of electrons from metals... electron rich materials from the left of the Periodic Tables as we face the Table, whose valence electrons are furthest removed from the positively charged nuclear core... and (ii) the gain of electrons by non-metals to the right of the Periodic Table as we face it.
We could represent these processes by the reaction...

We add the two redox processes together in such a way that the electrons are eliminated as virtual particles and we get a neutral salt... of a material and a non-metal that are held together by a strong electrostatic force of attraction...

where n is the amount of gases present in the mixture.
This relationship is due to the assumption that there are no attractive forces between the gases.
Total pressure of the Heliox mixtureIn this case, the total pressure of the Heliox mixture is calculated as:

Salts get dissolved in water because it has partial positive and negative charges. So option (c) is correct.
Why does salt dissolves in water?The water molecules pull the Na and Cl ions apart while breaking the ionic bond which held them together. After the salt ions are pulled apart, they get surrounded by water molecules. The salt dissolves to form a homogeneous solution.
The slightly positive portion of sodium is attracted to the slightly negative portion of oxygen on the water molecule. At the same time, the slightly electronegative chlorine moieties of NaCl are attracted to the slightly electropositive hydrogen moieties of water.In either case, no true bond is formed, the stronger covalent bonds of water (also commonly held by hydrogen bonds between water molecules) win, NaCl gets pulled apart, resulting in dissociation of Na+ and Cl- ions with the Na+ and Cl- ions setting loosely in place between the intact H₂O molecules. NaCl is then dissolved.Salts are ionic and are expected to dissolve in water because water itself is polar. Therefore, ionic salts are expected to dissolve in polar solvents.
