Answer:
D) Adding a catalyst
Explanation:
Adding a catalyst decreases activation energy and allows the reaction to occur more easily.
Answer:
(1) Bromination, (2) E2 elimination and (3) epoxidation
Explanation:
- In the first step, -OH group in cyclopentanol is replaced by more facile leaving group Br by treating cyclopentanol with
- In the second step, E2 elimination in presence of strong base e.g. NaOEt/EtOH produce cyclopentene
- In the third step, treatment of cyclopentene with mCPBA produces 1,2-epoxycyclopentane
- Full reaction scheme has been shown below
<u>Answer</u>:
"The earthquake shakes the position of land" is the most common way an earthquake changes Earth's land forms
<u>Explanation</u>:
Most of the times earthquake has been found to be making drastic reforms over the surface. With respect to the movement of ground other surface effects includes variation in the flow of groundwater, landslides and also in the direction flow change of mudflow. It affects the buildings, bridges, pipelines and railways and other important structures. the ground movement takes place due to the movement of underground rocks which found to be breaking near the faults. This release energy that further leads to movement of the tectonic plates. The generation of seismic wave from the energy.
Based on the question, it is evident that the question is based on Boyle's Law which we will use to find the answer necessary.
Now, Boyle's Equation: P₁V₁ = P₂V₂
V₂ = P₁V₁ ÷ P₂
∴ V₂ = (12.5L × 42.0 cm · Hg) ÷ 75 cm · Hg
⇒ V₂ = 7 L
Thus, the <span>volume when the pressure has increased to 75.0 cm Hg is 7 Litres.</span>
