Low electron affinity and large atomic radius
Metallic character decreases across a period (from left to right) and increases down a group.
Electron affinity increases from left to right within a period. This is caused by the decrease in atomic radius. Electron affinity decreases from top to bottom within a group. This is caused by the increase in atomic radius.
Explanation:
A chemical reaction is one in which a chemical change occurs.
During a chemical change;
- The process is irreversible
- New kinds of matter produced
- There is a change in mass
Based on these premise;
Baking cake batter is a chemical reaction because you cannot reverse the process
Shredding a paper is not a chemical reaction because no new kind of matter is produced.
Twisting of a metal wire is not a chemical reaction
Yellowing of newspaper in sunlight is a chemical change. The process cannot be reversed
This is true
Because when water evaporates molecules break and separate into different atoms
<h2>Answer:</h2>
The<u> diffusion </u>occurs in room.
- <u>Oder molecules move from their highest concentration to lowest concentration.</u>
<h3>Explanation:</h3>
Diffusion is a process by which molecules move down their concentration gradient. The process does not require any membrane.
So corner with perfume has high concentration of odor molecules. Hence they move to other corner with low concentration of molecules.
Ammonium sulfide
