Concentration of the water. The standard state for a liquid is the pure liquid, so the standard state of water is pure water, whose concentration is 55.5 M (in a liter, there are 55.5 moles of water, so its concentration is 55.5 mol/L).

Calculate the root main Square Velocity for the atoms in a sample of Nitrogen gas (N2) at 25°c of CO₂ and SO₂ from the same container and at the same temperature and pressure.
Answer:
To calculate the root mean square velocity of atoms in a gas, we need to know the mass of the atoms, the temperature of the gas, and the gas constant. The root mean square velocity can be calculated using the following equation:
v_rms = sqrt((3RT)/m)
Where v_rms is the root mean square velocity, R is the gas constant, T is the temperature in kelvins, and m is the mass of the atoms in kilograms.
For nitrogen gas (N2), the mass of each atom is 14/6.022 x 10^23 = 2.34 x 10^-23 kg.
For CO2, the mass of each atom is 12/6.022 x 10^23 = 2.0 x 10^-23 kg.
For SO2, the mass of each atom is 32/6.022 x 10^23 = 5.3 x 10^-23 kg.
Plugging these values into the equation, we can calculate the root mean square velocity for each gas at 25°C:
v_rms (N2) = sqrt((38.31298)/(2.34 x 10^-23)) = 466 m/s
v_rms (CO2) = sqrt((38.31298)/(2.0 x 10^-23)) = 505 m/s
v_rms (SO2) = sqrt((38.31298)/(5.3 x 10^-23)) = 691 m/s
Therefore, the root mean square velocity of atoms in a sample of Nitrogen gas at 25°C is 466 m/s, while the root mean square velocity of atoms in a sample of CO2 at the same temperature and pressure is 505 m/s, and the root mean square velocity of atoms in a sample of SO2 at the same temperature and pressure is 691 m/s.

8. Chemical bonds: Chemical bonds are forces of attraction that hold atoms or ions together. There are four main types of chemical bonds: covalent, ionic, metallic, and hydrogen bonds. Covalent bonds involve the sharing of electrons between two atoms, while ionic bonds involve the transfer of electrons from one atom to another. Metallic bonds involve the delocalization of electrons throughout a lattice of metal atoms, and hydrogen bonds involve the attraction between a hydrogen atom and another atom.

Which of the following is not a result of special additives blended into the monomer liquid and polymer powders?
longer shelf life.
color stability.
maximum flexibility.
maximum durability.
The following is not a result of special additives blended into the monomer liquid and polymer powders is maximum flexibility.
A monomer is the molecule that will combine to another identical monomer and form the polymers. A monomer is the simplest unit of the polymer. A polymer is the natural or it can be synthetic substance that is composed of the very large molecules and is called as macromolecules. A polymer is composed of the repeating units. the additive blended to the monomer is not the results in the maximum flexibility.
Thus, the maximum flexibility is not a result of special additives blended into the monomer liquid and polymer powders

calculate ecell for 1.0 m cu2 / 0.001 m zn2 : [ select ] tip: room temperature of 298 k can be assumed and use the e0cell for the cu/zn cell calculated from standard reduction potentials in q2.
In q2, the Cu/Zn cell was 1.041V by using standard reduction potentials.
As we have the formula
ZnZn 2+ (0.001M) Cu 2+ (0.1M) Cu
Overall cell reaction: ZnZn² +2e
Cu²+ +2e ⟶Cu
Zn+Cu 2+ Zn+Cu²+ Zn²+Cu
E cell o = cathode standard reduction potential + anode standard oxidation potential
E cell o = 0.34 to 0.76 V
E cell o =1.1 V
Kc = [Zn 2+ ] / [Cu 2+ ]= 10²
E cell o =1.1 V
K C = [Cu 2+ ] [Zn 2+ ] = 10 1
The cell's EMF at any electrode concentration is:
E=E o n 0.059 log(K C )=1.1 -0.059/2 X log(10² )=1.1 2 0.059 (2)
=1.10-059=1.041V

describe one chemical property of group 1 metals that results from the atoms of each metal having only one valence electron.
Alkali metals have a high electropositive polarity.This is so that each alkali metal's atom can readily create a positive ion by releasing its lone valence electron.
What are group 1's chemical characteristics? Electronegativity is a chemical characteristic of Group 1 metals that derives from each metal's atom having only one valence electron.Alkali metals are another name for Group I elements.Sodium, lithium, potassium, cesium, francium, and rubidium are some of them.In seawater, you can find them.Electronegativity is a chemical characteristic of Group 1 metals that derives from each metal's atom having only one valence electron.This refers to the atoms' propensity to attract electrons. Elements from Group 1 have similar properties.All of them are supple silver metals.These metals are highly reactive and have low melting temperatures due to their low ionization energy.As you descend the table, this family becomes more reactive.To learn more about chemical property refer to:
