Answer:
The answer to your question is letter A. 2
Explanation:
Data
Octane = C₈H₁₈
Oxygen = O₂
Carbon dioxide = CO₂
Water = H₂O
Reaction
C₈H₁₈ + O₂ ⇒ CO₂ + H₂O
Reactants Elements Products
8 C 1
18 H 2
2 O 3
This reaction is unbalanced
C₈H₁₈ + 25/2O₂ ⇒ 8CO₂ + 9H₂O
Reactants Elements Products
8 C 8
18 H 18
25 O 25
Multiply the reaction by 2
2C₈H₁₈ + 25O₂ ⇒ 16CO₂ + 18H₂O
Reactants Elements Products
16 C 16
36 H 36
50 O 50
Now, the reaction is balanced
It is called a Seismogram
Sodium, Potassium, and Cesium
Answer: Option (A) is the correct answer.
Explanation:
Plastic deformation is the change in shape of an object or metal caused by the load of excess stress.
Thus, metals experience plastic deformation when their crystal patterns have been disrupted by stress.
When stress is provided to the metal then their crystal pattern gets deformed resulting in change of shape of the metal. Plastic deformation is a permanent deformation.
