The following statement about soil formation are true:
1. The composition of soil depend largely on the composition of the parent rock.
2. Strong roots of shrubs and trees hold on to soil and protect it from erosion.
3. Soil formed from local rock is residual soil and soil formed from distant rock is transported soil.
Soil are typically formed from rocks. The nature of the soil depend on the type of rock from which the soil was formed. It takes a long time for a soil to be formed from a parent rock. Erosion is the process that carries the surface soil away, but the root of shrub and trees usually prevent this by holding on to the soil particles.
Answer:
Cu + 2AgNo3 is the reactants
Endocytosis is a type of bulk transport which involves the movement of large particles through the membrane in and out
Answer:
-586.56 kJ/mol is the standard enthalpy of the 3rd reaction.
Explanation:
...[1]
...[2]
..[3]
The unknown standard enthalpy of third reaction can be calculated by using Hess's law:
The law states that 'the heat absorbed or evolved in a given chemical equation is the same whether the process occurs in one step or several steps'.
[2] - 2 × [1] = [3]
The standard enthalpy of the 3rd reaction is -586.56 kJ/mol.The negative sign indicates that energy is released during this reaction.
The answer is Greenhouse effect
Hope this help
