Answer;
- A teacher takes the cap off a permanent marker. A few minutes later, students at the back of the classroom complain about the odor of the marker.
- A cooking school student burns a piece of toast. Soon, the entire kitchen smells like burnt toast.
- Toxic fumes produced by a chemical factory are detected in the air in a town several miles away.
<h3><u>Explanation;</u></h3>
- Diffusion is a type of passive transport that involves the movement of particles from a region of high concentration to a region of low concentration.
- <em><u>Diffusion takes place in liquids and gases, since their particles can move randomly from one region to another.</u></em>
- <em><u>Therefore, diffusion results from the random movement of particles in which the net movement is down the concentration gradient that is, from a region of high concentration to a region of low concentration.</u></em>
2ZnS(s)+3O2(g) -> 2Zns(s) + 2SO3(g)
the above given equation is unbalanced as it contains 4 moles of sulphur in the output but in the input there are only two aoms of sulphur so to balance the equation we will write the equation as given under
balanced equation is
2ZnS(s)+3O2(g) -> 2Zn(s) + 2SO3(g)
In words:
When 2 moles of solid zinc sulfide reacts with 3 moles of oxygen gas gives 2 moles of solid zinc and 2 moles of sulphur trioxide gas.
Checking if it is balanced:
C
3 3
H
8 4*2 = 8
O
8 3*2 + 4 = 6 + 4 = 10
8 10
Only O is not balanced.
So O is violating the law. Option C.

A single-displacement reaction, also known as asingle-replacement reaction, is a type of chemicalreaction<span> where an element reacts with a compound and takes the place of another element in that compound. This type of </span>reaction<span> is typically pictured like this: Here, A replaces B in the compound BC.</span>
