Equilibrium constants are known for the following reactions:
S(s) + (3/2)O2(g) SO3(g) Kc = 9.2 × 1023
SO3(g) SO2(g) + (1/2)O2(g) Kc = 4.8 × 10-4
Thus, for the reaction S(s) + O2(g) SO2(g), Kc = 4.4 × 1020.
Yolk
The nutrient-rich central part of an egg that serves as food for the developing embryo in egg-laying animals.
Cephalocaudal Pattern
A principle of physical growth that states development progresses from the head (cephalo) towards the tail (caudal), meaning children typically gain control over the head, chest, and arm muscles before those of the legs.
Spinal Cord
A long, thin, tubular structure made up of nervous tissue, extending from the brainstem to the lower back, which transmits neural signals between the brain and the rest of the body.
Sensory Systems
The part of the nervous system responsible for processing sensory information, allowing us to experience the world through sight, sound, touch, taste, and smell.
