Answer:

°C = -33.39 °C

K = 239.76 K

Explanation:

°C = ( °F -32 ) / 1.8
K = 273.15 + °C

⇒ °C = ( -28.1 - 32 ) / 1.8

⇒ °C = - 33.39 °C

⇒ K = 273,15 + (-33.39)

⇒ K = 239.76 K

what is the chemical reaction and mole ratio between oxalate and permanganate in the titration reaction

Tom [10]

5C2O4^(2-)(aq) + 2MnO4^-(aq) + 16H+(aq) → 10CO2(g) + 2Mn2+(aq) + 8H2O(l)` is the chemical reaction and mole ratio between oxalate and permanganate in the titration reaction.

A chemical reaction is a procedure that causes one group of chemical components to change chemically into another. Chemical reactions, which can frequently be described by a chemical equation, traditionally include changes that only affect the locations of electrons in the formation and dissolution of chemical bonds between atoms, with no change to the nuclei (no change to the elements present). The study of chemical processes involving unstable and radioactive elements, where both electronic and nuclear changes may take place, is known as nuclear chemistry.
