can the container hold?
Answers
0.216 moles of gas can the container hold if a sealed container can hold 0.325 L of gas at 1.00 atm and 293 K.
What is an ideal gas equation?The ideal gas law (PV = nRT) relates the macroscopic properties of ideal gases. An ideal gas is a gas in which the particles (a) do not attract or repel one another and (b) take up no space (have no volume).
PV=nRT, where n is the moles and R is the gas constant. Then divide the given mass by the number of moles to get molar mass.
Given data:
R = gas constant = 0.08206 L.atm / mol K
T = temperature, Kelvin
V=5 L
P = 1.05 atm
T = 296 K
Putting value in the given equation:
[tex]\frac{PV}{RT}=n[/tex]
[tex]n= \frac{1.05 atm\; X \;5 L}{ 0.08206 L.atm / mol K X 296 K}[/tex]
Moles = 0.216 moles
Hence, 0.216 moles of gas can the container hold if a sealed container can hold 0.325 L of gas at 1.00 atm and 293 K.

A 1. 07 g sample of a noble gas occupies a volume of 363 ml at 35°c and 678 mmhg. Identify the noble gas in this sample. (r = 0. 08206 l×atm/k×mol)
Answers
The identity of the noble gas is the sample is Krypton
Ideal Gas lawFrom the question, we are to determine the identity of the noble gas in the sample
From the ideal gas equation, we have that
PV = nRT
∴ n = PV / RT
Where P is the pressure
V is the volume
n is the number of moles
R is the gas constant
and T is the temperature
From the given information,
P = 678 mmHg = 0.892105 atm
V = 363 mL = 0.363 L
R = 0.08206 L.atm/mol.K
T = 35 °C = 35 + 273.15 K = 308.15 K
Putting the parameters into the equation, we get
n = (0.892105 × 0.363)/ (0.08206 × 308.15)
n = 0.0128 moles
Now, we will determine the Atomic mass of the sample
Using the formula,
Atomic = Mass / Number of moles
Atomic mass of the substance = 1.07 / 0.0128
Atomic mass of the substance = 83.6 amu
The noble gas with the closest atomic mass to this value is Krypton.
Molar mass of Krypton = 83.798 amu
Hence, the identity of the noble gas is the sample is Krypton

What causes ionic bonding between two atoms?
Answers
Answer:
Ionic bonding happens when an atom of an element gives one or more of its electrons to the other element's atom..it usually takes place between metal and non metal atoms...like in NaCl, Na gives its valence electron to chlorine and completes its own octet. Chlorine accepts the electron and completes its own octet too...but now both the atoms have an opposing charge and hence they attract each other to form an IONIC bond.
Ionic bonds are the strongest of the bonds...here complete transfer of electrons takes place unlike covalent bonds.

Law of conservation of energy states that energy can neither be created nor destroyed, but it can be transferred from one form to another.
Molecules can move so they show kinetic energy, molecules can be there at many positions so they can show potential energy, molecules can vibrate so they can show sound energy but molecules can only absorb light hence they can't have light energy.

Recall all the models you described in task 1.(Bohr, Rutherford, Thomson, and Dalton) Think about the results each model would predict for Thomson’s experiment. Which atomic models does Thomson’s experimental evidence support? Explain why these models are compatible with the experimental results.
Answers
Thomson's experimental data does support the Rutherford model.
What is an atom?The atom consists of matter that may be split without releasing electrical charges.
It's also the smallest unit of matter with chemical element features. As a result, the atom is the fundamental unit of science.
Rutherford was the one who first published the nuclear model of the atom. According to his atomic model, an atom's volume is largely empty,
The center of the atom houses the nucleus, which is made up of protons and neutrons, and its electrons follow certain pathways as they orbit it.
When compared to Rutherford's discoveries, the study of certain other scientists, like Dalton, Neil Bohr, and JJ Thomson, is mostly consistent.
For instance, Dalton's atomic theory assumed that atoms interact to create compounds and are nearly the same size.
Rutherford's theory states that atoms have a finite amount of electrons that may be shared to form compounds.
Rutherford's discoveries, which gave rise to the concept of shells, are also consistent with the Bohr model, which holds that electrons orbit the nucleus in certain shells.
Despite the fact that Rutherford's model was the best atomic model, it nevertheless drew from a number of prior studies and was compatible with their findings.
Hence Thomson's experimental data does support the Rutherford model.

Answers
Since the helium gas has a volume of 1.00 L, the final volume of the helium gas is 1.00 L
To find the volume, we need to know the general gas law.
What is the general gas law?The general gas law is given by P₁V₁/T₁ = P₂V₂/T₂ where
P₁ = initial pressure of gas, V₁ = initial volume of gas, T₁ = initial temperature of gas in Kelvin, P₂ = final pressure of gas, V₁ = final volume of gas, andT₁ = final temperature of gas in KelvinFinal volume of helium gasSo, making V₂ subject of the formula, we have
V₂ = P₁V₁T₂/T₁P₂
Since the sample of helium gas has a volume of 1.00 L and both the pressure and kelvin temperature each double, we need to find its final volume.
So,
P₂ = 2P₁, T₂ = 2T₁ and V₁ = 1.00 LSo, substituting the values of the variables into the equation, we have
V₂ = P₁V₁T₂/T₁P₂
V₂ = P₁V₁ × 2T₁/T₁ × 2P₁
V₂ = V₁
V₂ = 1.00 L
