Answer:

In homeothermic (“warm-blooded”) animals, body temperature is carefully

regulated. The hypothalamus, located in the brain, acts as the master ther-

mostat to keep body temperature constant to within a fraction of a degree

Celsius in a healthy animal. If the body temperature starts to deviate much

from the desired constant level, the hypothalamus causes changes in blood

flow and initiates other processes, such as shivering or perspiration, to bring

the temperature back to normal. What evolutionary advantage does a con-

stant body temperature give the homeotherms (e.g., birds and mammals)

over the poikilotherms (e.g., reptiles and insects), whose body temperatures

are not kept constant? What are the disadvantages?

__ SnCl4 → __ Sn + __ Cl2

Kisachek [45]

Answer:

Sn (s) + 2 Cl2 (g) → SnCl4 (l)

This is an oxidation-reduction (redox) reaction:

4 Cl0 + 4 e- → 4 Cl-I

(reduction)

Sn0 - 4 e- → SnIV

(oxidation)

Cl2 is an oxidizing agent, Sn is a reducing agent.
