Answer:
E°red for Tl³⁺(aq) | Tl⁺(aq) is 0.78 V
Explanation:
According to cell reaction we can predict which one cathode half cell and which one anode.
We know left hand side electrode where oxidation occur acts as an anode and right hand side electrode where reduction take place acts as an cathode.
Hence Cr²⁺ converted into Cr³⁺ since oxidation is take place where as Ti³⁺ converted into Ti⁺ means reduction take place.
<u>Anode half cell </u>is Cr³⁺(aq) | Cr²⁺(aq) is E⁰red = -0.41 V
<u>Cathode half cell</u> is Ti³⁺(aq) | Ti⁺(aq) is E⁰red = ?
E⁰cell = E⁰cathode - E⁰anode
⇒ E⁰cathode = E⁰cell + E⁰anode
⇒ E⁰cathode = 1.19 + (- 0.41) volt = 0.78 V
The glare is the result of the specular reflection of the beam of light from an oncoming car. Normally a roadway would cause diffuse reflection due to its rough surface. But if the surface is wet, water can fill in the crevices and smooth out the surface.
Answer: We live at the bottom of a gaseous envelope the atmosphere--that is bound gravity to the planet Earth. The circulation of our atmosphere is a complex process because of the Earth's rotation and the tilt of its axis. The Earth's axis is inclined 23.5° from the ecliptic, the plane of the Earth's orbit around the Sun. Due to this inclination, vertical rays of the Sun strike 23.5° N. latitude, the Tropic of Cancer, at summer solstice in late June. At winter solstice, the vertical rays strike 23.5° S. Latitude, the Tropic of Capricorn. In the Northern Hemisphere, the summer solstice day has the most daylight hours, and the winter solstice has the fewest daylight hours each year. The tilt of the axis allows differential heating of the Earth's surface, which causes seasonal changes in the global circulation. On a planetary scale, the circulation of air between the hot Equator and the cold North and South Poles creates pressure belts that influence weather. Air warmed by the Sun rises at the Equator, cools as it moves toward the poles, descends as cold air over the poles, and warms again as it moves over the surface of the Earth toward the Equator. This simple pattern of atmospheric convection.
