Answer:
It's H3O+.
Explanation:
The H3O+ ion in the solution is what gives it its acidic properties ( sour taste, low pH , for example). Its known as the hydronium ion.
Answer:

Explanation:
A is false.
● activation energy affects the rate of a reaction and catalyst affects the rate of reaction too
ΔG (change in free energy) tells if a reaction is spontaneous or not
C. A hypothesis :) hope this helped
Answer:
(a). The path length is 3.09 m at 30°.
(b). The path length is 188.4 m at 30 rad.
(c). The path length is 1111.5 m at 30 rev.
Explanation:
Given that,
Radius = 5.9 m
(a). Angle 
We need to calculate the angle in radian

We need to calculate the path length
Using formula of path length



(b). Angle = 30 rad
We need to calculate the path length


(c). Angle = 30 rev
We need to calculate the angle in rad


We need to calculate the path length


Hence, (a). The path length is 3.09 m at 30°.
(b). The path length is 188.4 m at 30 rad.
(c). The path length is 1111.5 m at 30 rev.
<span>An emf is induced when a magnet is in the middle of coil because when a magnetic field is changing then it produces a voltage in the coil, which causes a current to flow. If the coil is changed through a magnetic flux, then a voltage is produced.</span>
