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.

b). The periodic table's second group of transition metals is Group 4. The four elements that make up this substance are titanium, zirconium, hafnium, and Rutherfordium. In honor of its lightest member, the group is sometimes known as the titanium group or titanium family.
c). Periods are the horizontal rows or lines that make up the periodic table. "Groups" are the vertical lines or columns.
d). Titanium is the common element of Group 4 and row 4.

Which statement comparing ionic bonds and covalent bonds is correct?
Covalent bonds tend to be less polar than ionic bonds, which is an accurate way to compare the two types of bonds.
How are ionic and covalent bonding compared?An atom can participate in covalent and ionic bonds, which are the two main types of bonds. By sharing electrons, two or more atoms can form covalent bonds. When two or more ions come together, their opposing charges hold them together to form ionic bonds.
What is true regarding covalent bonding according to the following statements?Response and Justification: The right answer is (a). Covalent bonds are formed when the orbitals of two atoms overlap. Because the sharing of electrons creates covalent bonds.

Which of the following statements is correct about covalent bonding?
How many neutrons does cobalt have if its atomic numbers is 27 and its mass number is 59?; How many protons neutrons and electrons are there of cobalt has an atomic number of 27 a mass number of 58 and a charge of 3?; How many neutrons are present if cobalt has an atomic number of 27 a mass number of 59 and a charge of 3?; What is the number of protons of cobalt if it has a number of 27 in atomic number?; How many neutrons does an atom have if its mass number is 27 and it has 13 protons?; How many neutrons in atomic number is 27?
for the above example there are 27 protons, 31 neutrons, 27 electrons
Atomic number is equal to the number of protons and equal to the number of electrons. So 27 = number of protons = Number of electrons. Mass number is the sum of the number of proton and neutrons Mass number = 58 = Number of proton + Number of neutrons .Number of neutrons = Mass number - Number of protons 58-27=31 The charged amount of an atomic nucleus is the chemical element's atomic number, also known as nuclear charge number. For conventional nuclei, this is equivalent to the proton count or the amount of protons in the nucleus of every atom in that element

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:
