The surface area will be:
S.A. = 6l²
S.A = 6(100 x 10⁻⁶)²
Volume = l³
Volume = (100 x 10⁻⁶)³
Surface area to volume ratio:
[6(100 x 10⁻⁶)²] / (100 x 10⁻⁶)³
S.A : Vol = 6 x 10⁴
I believe the process by which ions join to reform the solid is called precipitation. It is a process in which ions leave a solution and regenerate an ionic solid. For example; Ag+(aq) + Cl-(aq) = AgCl (s). Dissolution on the other hand is the process in which an ionic solid dissolves in a polar liquid; it is the opposite of precipitation.

Answer:
The two major differences lies in the function and support system.
Explanation:
The two major differences between an endocrine and an exocrine system are as follows –
a) An endocrine system releases its produce (hormones) into the connective tissue i.e blood while the exocrine system releases hormones directly into the ducts so that it could reach the targeted tissue directly.
For example – the Adrenal gland is an endocrine gland that secretes adrenaline directly into the blood. The salivary gland is an exocrine gland that releases its produce into the collecting duct leading to mouth. However, Pancreas is both endocrine and exocrine gland.
b) The endocrine system cannot work alone therefore it works in coordination with the nervous system to control actions and balance the body. However, the exocrine system works independently
