Answer:
Explanation:
Here, we want to get the partial pressure of the Helium gas
To get this, we need to know the mole fraction of each of the gases
To get the number of moels of chlorine gas, we have to divide the mass of the chlorine gas by its molar mass
The molar mass of the chlorine gas is 71 g/mol
Thus, we have the number of moles as:
For the Helium, we have to divide the mass given by the atomic mass
The atomic mass of helium is 4 amu
Thus, we have the number of moles as:
According to Dalton's law of partial pressure, the total pressure is the sum of the individual partial pressure
We can get the mole fraction of the helium by dividing the number of moles of the helium by the total number of moles
We have the partial pressure as:
Well partly yes because air pollution can happen when we burn fossil fuels, it can happen when we use vehicles and household/farming chemicals can cause air pollution so yes it is caused by humans

Explanation:
1. subatomic particles.
2.proton, electron and neutron
3.The atomic mass of an element is actually the sum of the MASSES of protons and neutrons in AN atom of that element
4.An element's atomic number is equal to the number of protons in the nuclei of any of its atoms
5. Number of Protons = Atomic Number
Number of Electrons = Number of Protons = Atomic Number
Number of Neutrons = Mass Number - Atomic Number
For krypton:
Number of Protons = Atomic Number = 36
Number of Electrons = Number of Protons = Atomic Number = 36
Number of Neutrons = Mass Number - Atomic Number = 84 - 36 = 48
6. electron, lightest stable subatomic particle known. It carries a negative charge of 1.602176634 × 10−19 coulomb, which is considered the basic unit of electric charge. The rest mass of the electron is 9.1093837015 × 10−31 kg
7.The center of the atom is called a nucleus
8. Negatively charged particles are found in multiple layers outside the nucleus of the atom. These particles are called electrons, and they orbit in various energy levels around the atom's nucleus.
9. A charged particle is also called an ion
The mass number is defined as the total number of protons and neutrons in an atom.
