Same size mass and composition
Answer:
Molecules start out unevenly distributed and end up evenly distributed.
Explanation:
Diffusion is the process by which molecules of a substance move from a region of higher concentration to a region of lower concentration until equilibrium is attained.
Molecules start out unevenly distributed and end up evenly distributed in a particular medium. Diffusion occurs due to the particulate nature of matter. When the particles that make up a substance are concentrated at a point, the collide more often with one another causing each molecule to spread out in order to occupy all the available space.
Diffusion occurs in gases, liquids and solids but occurs fastest in gases. Diffusion can be observed for example, in the spread of the smell of a dead rat from one point in a room to every part of the room.
3H₂ + N₂ = 2NH₃
V(H₂)/3 = V(NH₃)/2
V(NH₃)=2V(H₂)/3
V(NH₃)=2*4.50/3=3.00 L
3.00 L
Answer: The resultant pressure is 3.22 atm
Explanation:
Gay-Lussac's Law: This law states that pressure is directly proportional to the temperature of the gas at constant volume and number of moles.
(At constant volume and number of moles)
where,
= initial pressure of gas = 2.79 atm
= final pressure of gas = ?
= initial temperature of gas = 273K
= final temperature of gas = 315 K
Thus the resultant pressure is 3.22 atm
Answer:
<h3>The answer is 19.3 g/cm³</h3>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 57.9 g
volume = 3 cm³
We have
We have the final answer as
<h3>19.3 g/cm³</h3>
Hope this helps you
