1284.689 grams of sodium nitrate will be produced from 15.1 moles of silver nitrate.

To determine how many grams of sodium nitrate will be produced from 15.1 moles of silver nitrate, we need to perform a balanced equation and stoichiometry calculation.

The balanced equation for the reaction between silver nitrate and sodium chloride to form silver chloride and sodium nitrate is:

AgNO3 (aq) + NaCl (s) → AgCl (s) + NaNO3 (aq)

We know that 15.1 moles of silver nitrate will react with the stoichiometric amount of sodium chloride, which is 1 mole of sodium chloride for every 1 mole of silver nitrate.

So, we can calculate the moles of sodium nitrate that will be produced by multiplying the moles of silver nitrate by the coefficient of sodium nitrate in the balanced equation:

15.1 moles AgNO3 * 1 mole NaNO3 / 1 mole AgNO3 = 15.1 moles NaNO3

To convert the moles of sodium nitrate to grams, we can use the molar mass of sodium nitrate, which is 84.99 g/mol.

15.1 moles NaNO3 * 84.99 g/mol = 1284.689 g

So, 1284.689 grams of sodium nitrate will be produced from 15.1 moles of silver nitrate.

Interactions between two hexane molecules occur through London dispersion forces, which are weak intermolecular forces that arise due to the temporary dipoles produced by the motion of electrons in the molecules.

These forces become stronger as the molecules become larger, and so hexane molecules, which have long hydrocarbon chains, experience fairly strong London dispersion forces. These forces allow the hexane molecules to interact with one another in a way that they can form weak associations, which are important for the formation of liquid hexane.

Additionally, when two hexane molecules approach one another, they may also experience dipole-dipole interactions, which are slightly stronger than London dispersion forces. These interactions occur when the molecules have a slightly different distribution of electrons and attract one another.

Lastly, hexane molecules can also experience hydrogen bonding, which is the strongest intermolecular force and occurs when a hydrogen atom covalently bonded to an electronegative atom is attracted to an electronegative atom in a different molecule.

Similar to how ions are created when neutral atoms acquire or lose electrons, polyatomic ions are created when neutral molecules gain or lose electrons. Because the total number of electrons in the molecule is more than the total number of protons in the molecule, a polyatomic ion is a collection of covalently bound atoms with a net charge. A polyatomic ion's net charge must be equal to the formal charges added to each of its atoms in the Lewis dot structure.

A molecule that has been ionised by gaining or losing electrons is referred to as a polyatomic ion. The group of atoms that are covalently linked together to form a polyatomic ion has a net charge because the total amount of electrons and protons in the molecule is not equal. When depicting Lewis dot structures, the total charge on a polyatomic ion is equal to the sum of the formal charges on each of the atoms in the ion.

The mass of O2 gas is about 6.9 g.

It is a law which link a gas's pressure, volume, and temperature.

The ideal gas law states that PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant, and T is the temperature in Kelvins.

We can use this equation to find the number of moles of gas, and then use the molar mass of O2 to find the mass of the gas.

First, we can rearrange the ideal gas law to solve for n:

n = (PV) / (RT)

We know that P = 0.900atm, V = 21.4L, R = 0.08206 Latm/molK, and T = 257K.

Substituting these values into the equation:

n = (0.900atm * 21.4L) / (0.08206 Latm/molK * 257K)

Now we know the number of moles of O2 gas. To find the mass, we can use the molar mass of O2, which is 32.00 g/mol.

mass = n * molar mass

mass = n * 32.00 g/mol

So, the mass of O2 gas is about 6.9 g.

The four properties of plastics are malleability, longevity, cheapness, and poor conductivity.

Plastics are generally very malleable and can be molded into different shapes very easily. Different types of plastics have different melting points, which enables them to be shaped into different shapes and make objects.

Plastics are generally very durable and have a long shelf life. That is the reason why plastics are used to make things that go through a lot of wear and tear. A negative aspect of this is that plastics, when exposed to natural processes of degradation, do not break down easily and harm the environment.

Plastics are usually cheap and can be obtained at a very less price. This helps people afford goods made out of plastic and also reduces the production cost of the goods.
