In order to determine how many moles of CO2 provide 2 moles of H2CO3, we must look at the balanced reaction and compare the coefficients of each compound.

CO2 + H2O --> H2CO3

The equation above is already balanced; therefore, for every 1 mole of CO2, we get 1 mole of H2CO3.

2 moles H2CO3 x (1 mole CO2)/(1 mole H2CO3) = 2 moles CO2.

We simply convert the moles of H2CO3 to moles of CO2, which results in 2 moles of CO2 required to give 2 moles of H2CO3.

Aluminum is one of the main factors that reduce plant growth in acid soils. Although it is generally harmful to plants in soils with a neutral medium, the concentration of positive aluminum ions in acid soils increases and malfunctions in root and function growth.

Most acid soils are saturated with aluminum rather than hydrogen ions. Soil acidity is the result of hydrolysis of aluminum compounds. This principle (lime correction) to determine the degree of base saturation in the soil has become the basis of the methods used in soil testing laboratories to determine the lime requirements for soil. Application of lime to soil reduces the toxicity of aluminum to plants. Note This connector loads slowly.

Adaptation of wheat to allow aluminum to be carried out is due to the fact that aluminum releases organic compounds that in turn combine with harmful aluminum cations. It is believed that sorghum has the same endurance. The first genes found to withstand aluminum were found in wheat. Aluminum sulphide bearing has been found to be governed by an individual gene, such as in wheat. This is not the case in all plants.
