Answer:
you wont be able to ask any more questions until you answer some bc you get points from answering questions but you loose points when you ask them
Explanation:
Explanation:
Scientist Evidence Model
Dalton Gases indivisible, solid and spheres
J.J Thomson Deflected beam Negative charges evenly scattered
through positively charged mass of
matter.
Rutherford Deflection of alpha atomic model
particles passing
through the gold foil
The emboldened words are the answer.
- John Dalton proposed the first model of the atoms by his works on gases. He postulated the Dalton's law of partial pressure.
- He suggested that gases are made of tiny particles called atoms.
- J.J Thomson proposed the plum pudding model of the atom in which the charges are evenly scattered through the positively charged mass of matter.
- The gold foil experiment by Rutherford brought the atomic model of the atoms in the front-light.
- The model suggests a small positively charged center which the mass of the atom.
- The outer space is occupied by the electrons.

Answer:
C.) 3.5 atm
Explanation:
Because you are dealing with pressure and volume, you can use Boyle's Law to help you find the missing variable. The general formula looks like this:
P₁V₁ = P₂V₂
In this formula, "P₁" and "V₁" represent the pressure and volume of the chamber originally. "P₂" and "V₂" represent the final pressure and volume. You have been given the values of all the other variables but "P₂". Therefore, you can plug these values into the formula and simplify to find the final pressure.
P₁ = 1.5 atm
V₁ = 1.4 L
P₂ = ?
V₂ = 0.60 L
P₁V₁ = P₂V₂ <---- Boyle's Law formula
(1.5 atm)(1.4 L) = P₂(0.60 L) <---- Plug in values
2.1 = P₂(0.60 L) <---- Multiply 1.5 and 1.4
3.5 = P₂ <----- Divide both sides by 0.60
The correct answer is C because diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration.
HOPE THIS HELPS!
HAVE A GR8 DAY ;-)
