Answer:
- Daniel- Earth and Space
- Sanya- Chemistry
Explanation:
Daniel's study field is associated with the '<u>Earth and Space</u>' as he is attempting to explore how the frequency of tropical storms(in the atmosphere) and coastal erosion(relation with land and ocean) are interconnected to each other. He studies how the two are associated and affect life on the planet.
While Sanya's field of study would be '<u>Chemistry</u>' as she aims to study the composition and constitution of substances and the changes that they undergo as a consequence of alterations in the constitution of their molecules('whether the discharge from industrial plants has any impact on the pH concentration of freshwater swamps in the surrounding area').
When a liquid evaporates, it releases heat energy into the surroundings because the molecules obtain energy ( when they are being evaporates), causing the molecules to vibrate fast and escape into the atmosphere!
Answer:
The answer is Ce^4+ (aq) + Mn^2+ (aq) ==> Ce^3+ (aq) + Mn^3+ (aq)
Explanation:
The reaction is first order with respect to Ce^4+ and first order with respect to Mn^2+ below.
Ce^4+ (aq) + Mn^2+ (aq) ==> Ce^3+ (aq) + Mn^3+ (aq)
The rate calculation,
Ce^4+ (aq) + Mn^2+ (aq) ==> Ce^3+ (aq) + Mn^3+ (aq)
This is the catalyzed reaction.
This is only true for the titration of a strong acid with a strong base or vice versa. At the equivalence point of the titration of a weak base with a strong acid the pH is less than 7.00 and at the equivalence point of the titration of a weak acid with a strong base the pH is greater than 7.00.
