The ability of Anthony to be able to smell the gas in his house because of the activation of his olfactory receptors through the process of sensation.
<h3>What is olfactory system?</h3>
The olfactory system refers to the sense of smell. Human being feel the sensation of smell through the nose. The nose is the organ of the body responsible for perceiving both good and bad odor.
There are five major sense organs in the body:
- Eyes - Sight
- Nose - Smell
- Tongue - Taste
- Skin - Touch
- Ears - Hearing

<h2 /><h3>Which of these is an agent of chemical weathering?</h3>
<h3>
<em>Answer</em><em>;</em><em> </em><em> </em><em> </em><em>The primary agents in chemical weathering are water, oxygen and acids. Explanation: These react with surface rocks to form new minerals that are stable in,or in equibrilium with the physical and chemical conditions present on the earth's surface</em></h3>

The only reaction that will most likely take place based on the activity series is; C: Ba + Na₂CO₃
<h3>Activity Series</h3>
From the activity series given, we can say that during a displacement reaction, the more reactive metal will always displace the lesser reactive metal from a compound.
Let us look at each of the given options;
A) Ag + FeCl₃
From the activity series, Silver(Ag) is less reactive than Iron(Fe) and as such Silver cannot displace iron from its' compound.
B) Zn + CaO
Zinc (Zn) is a less reactive metal than Calcium (Ca), so it cannot cannot displace Calcium from its' compound.
C) Ba + Na₂CO₃
Barium (Ba) is a more reactive metal than Sodium (Na), and therefore Barium will displace sodium from its compound in a displacement reaction.
D) Cr + KNO₃
Chromium (Cr) is a lesser reactive metal than Potassium (K), and it therefore cannot displace Potassium from its compound.
Complete question is;
Which reaction will most likely take place based on the activity series? Li > K Ba > CaNa > Mn > Zn > Cr> Fe> Cd Ni > H > Sb > Cu > Ag > Pd > Hg > Pt
A. Ag + FeCl₃
B. Zn + CaO
C. Ba + Na₂CO₃
D. Cr + KNO₃
