Chemical weathering is when things get weathered chemically
The chemical reaction is expressed as:
2H2 + O2 = 2H2O
To determine the amount of oxygen used in the reaction, we use the amount of water produced and the relation of the substances in the reaction we do as follows:
209 g H2O ( 1 mol / 18.02 g ) ( 1 mol O2 / 2 mol H2O ) ( 32 g / 1 mol ) = 185.57 g O2
<span>Deciduous forests have a long, warm growing season as one of four distinct seasons.There is abundant moisture.The soil typically is rich. The leaves dropped from trees provide a steady source of organic material for the soil. Many species live in the soil and break down the organic matter.Tree leaves are arranged in strata: canopy, understory, shrub, and ground. A great deal of light is therefore filtered out before it reaches the ground.With the dropping of their leaves during one season, trees stop photosynthesis and enter a dormant period.<span>Three main types of trees are characteristic of these forests: northern hardwood, central hardwood, and southeast pine and oak.
