Using the ideal gas equation:
PV = nRT, we can form:
V/n = constant
Thus,
V₁/n₁ = V₂/n₂
n₂ = 2.3 x 85.5/50.5
= 3.89 moles
Timbuktu was considered a MASSIVE trade center in Mali. That is how all of the foreign goods came into the kingdom. It also had education centers which was very important in Mali.
Calcination use temperatures roughly twice that of typical roasting. The main idea is to use high temperatures and decompose the material being heated fairly faster. Roasting tries to changes the food products by starting and supporting a number of chemical reactions within the food that results in pleasant flavor, greater availability of certain ingredients.
There are five main modes of seed dispersal: gravity, wind, ballistic, water, and by animals. Some plants are serotinous and only disperse their seeds in response to an environmental stimulus. Dispersal involves the letting go or detachment of a diaspore from the main parent plant.
Fruits and seeds dispersal is the process whereby fruits and seeds are scattered from their origin. The various ways by which fruit and seed are dispersed are known as agents of seed and fruit dispersal.
