The volume of gas in the tank is determined as 1.78 L.

The volume of gas in the tank is calculated by applying idle gas law as follows;

PV = nRT

where;

n = reacting mass / molar mass

n = (300 g) / (3 x 16 g)

n = (300 g) / (48 g/mol)

n = 6.25 moles

The volume of the gas is calculated as follows;

V = nRT/P

V = (6.25 x 8.314 x 214.25)/(6250)

V = 1.78 L

Thus, the volume of ideal gas increases with increase in temperature.

The pre-partition salicylic acid solution (not mixing with chloroform) serves a second propose to act as a standard for linear regression analysis.

What is salicylic acid?

The chemical formula for salicylic acid is HOC6H4CO2H. It is a colorless, bitter-tasting substance that serves as both an aspirin precursor and metabolite (acetylsalicylic acid). It is a plant hormone that has been classified as an experimental teratogen by the EPA's Toxic Substances Control Act (TSCA) Chemical Substance Inventory. The word for willow tree in Latin is salix. Some anti-acne products contain it as an ingredient. Salicylates are the name for the salts and esters of salicylic acid.

The pre-partition salicylic acid solution (not combining with chloroform) acts as a benchmark for linear regression analysis in addition to serving as a comparison to the post-partition salicylic acid solution.

The simplest molar ratio in which lithium reacts with nitrogen is 6 moles of lithium to 1 mol of nitrogen.

What is molar ratio?

A molar ratio examines the ratio that exist between two chemical compounds showing the amounts in moles of the compounds involved in a chemical reaction.

Molar ratio = amount of a constituent in moles ÷ total amount of all constituents in a mixture in moles

Given:

Mass of lithium (Li) = 4.2 g

Mass of  nitrogen (N2) = 2.8 g

Total amount of mass = 7g

Moles = molecular weight  ÷  mass of water

Moles of lithium (Li) = 4.2 ÷ 7 = 0.60 mol

Moles of nitrogen (N₂) = 2.8 ÷ 7 =  0.10 mol

Therefore, ratio Li : N₂ = 0.60 : 0.10 = 6 : 1

6 Li + N₂

The balanced equation between lithium and nitrogen, to form lithium nitride = 6 Li + N₂ → 2 Li₃N₆L i + N₂ → 2Li₃N

In summary, the simplest molar ratio in which lithium reacts with nitrogen is 6:1

To calculate the number of barium atoms present in two moles of barium, we need to multiply the moles of barium by Avogadro's number (B)

A mole of a compound contains 6.022 x [tex]10^{23}[/tex] atoms.

6.022 x [tex]10^{23}[/tex] atoms is the Avogadro’s number which denotes the molecular weight in grams.

Thus, one mole of barium would have 6.022 x [tex]10^{23}[/tex] barium atoms

Therefore, two moles of barium would be multiplication of number of moles of barium by Avogadro’s number

Pancakes are warmth due to conduction. When there is conduction in a system, there is change in temperature and energy.

When a system absorbs or loses warmth, the common kinetic energy of the molecules will exchange. Consequently, warmth transfer effects in a change inside the machine's temperature so long as the machine is not undergoing a segment trade.

The change within the inner power of a gadget is the sum of the heat transferred and the paintings carried out. The heat glide is same to the exchange within the inner energy of the device plus the work performed.

When the temperature of an object will increase, the average kinetic energy of its particles increases. When the average kinetic power of its debris will increase, the object's thermal energy increases. consequently, the thermal energy of an object will increase as its temperature increases.

Electrons are the components of the atom that are found outside of the nucleus.

In contrast to protons and neutrons, which are found inside the atom's nucleus, electrons are found outside the nucleus. Negative electrons are drawn to the positive nucleus because their opposing electric charges attract one another. This force of attraction keeps electrons flowing continuously in the otherwise empty area surrounding the nucleus, this force of attraction keeps electrons flowing continuously.

Since they are so tiny, electrons. Since an electron's mass is only a tiny fraction of that of a proton or neutron (approximately 1/2000), it is almost entirely absent from the overall mass of an atom. Electrons have an electric charge of -1, which is equivalent to but in the opposite direction of the proton's electric charge of +1.

Since there are exactly as many electrons in an atom as there are protons, the positive and negative charges "balance out," leaving the atom electrically neutral.

The true statements about the electron sea model is;

The term bonding has to do with the situation in which there is a combination of the atoms that come from two or more elements. Now let us note that formation of a bond means that the properties of the elements would cease to be individually observed once a bond has been formed.

Having said this, let us talk about the metallic bond. The metallic bond is the kind of bond that occur between the positive ions of the metal and the electron cloud or sea that have left the ions. It then follows that the bond is formed by the electrostatic interference that occurs between the electron sea and the positive ions.

A substance diffuses when it moves from a region of high concentration to one of low concentration. Because the particles in liquids and gases travel randomly from one location to another, diffusion occurs in these media. For living things, diffusion is a crucial process because it governs the flow of materials into and out of cells.

A net migration of anything from a zone of higher concentration to a location of lower concentration can also be described as it, and a gradient in concentration is what's driving it.

Without spending the cell's energy, substance that crosses a cell membrane travels away from the region where it is concentrated.

Passive transport is the term for it.

It is the process by which substances migrate down the gradient of concentration without utilizing cellular energy.

Simple diffusion is another name for it.

Due to the difference in concentration from the perfume bottle to the outside environment, when a perfume bottle is opened, particles disseminate in the air.

Non-volatile mixtures can be separated using a process called thin layer chromatography (TLC). Since acetaminophen has a hydroxyl group, it is more polar than phenacetin.

Since acetaminophen has a hydroxyl group, it is more polar than phenacetin. Phenacetin will be more soluble and migrate to the top than the polar component because we are employing a non-polar solvent.

Non-volatile mixtures can be separated using a process called thin layer chromatography. The experiment is carried out on a piece of glass, plastic, or aluminum foil that has been lightly covered with an adsorbent substance. Typically, silica gel, cellulose, or aluminum oxide are utilized as the substance.

Because acetaminophen is more polar than phenacetin and nonpolar molecules pass through silica gel more quickly than polar ones do, acetaminophen would have a lower Rf value.

When the use of significant figures and rounding up is applied correctly the mass of the mixture will be 80.5 g.

In cases of addition or subtraction, only the last significant figure of every number is taken into account.

In 30.05, this is 5, in the hundredths. When we look at 50.0, the last significant figure is 0, and it is in the tenths. And in 0.4006, the last significant figure is 6, in the ten thousandths. Of these three, the 0 from 50.0 is in the leftmost position, which means that the last significant figure of the result needs to be in the same position (in the tenths).

Moving onto the actual algebraic operation:

30.05 g + 50.0 g + 0.4006 = 80.4506 g

As we established, the last significant figure should be in the tenths, and we will have to round up 4 to 5 (trailing numbers are greater than 0), which means that the resulting mass will be 80.5 g.
