Cation exchamnge capacity is directly related to the clay fraction within the soil. For lateritic soil, the surface of clay fracion is coated with the gels of sesquioxides which inturn reduces the surface activity of clay particles...
Sandy soil tends to be more acidic because it has low cation exchange capacity and is less able to retain nutrients, leading to leaching of bases such as calcium and magnesium. This can result in a lower pH level in sandy soils.
Sandy soil is less fertile because it has larger soil particles, which results in poor water retention and nutrient retention. The large pore spaces in sandy soil allow water and nutrients to leach through quickly, making it difficult for plants to uptake them for growth. Additionally, sandy soil has a lower cation exchange capacity, meaning it has less ability to hold onto essential nutrients for plant uptake.
a cation is not an element, it is a positively charged ion, which means that it has less electrons than protons
Iron oxide
donate the electrons forming a cation.
the specie will become a cation
Lung capacity is measured by a spirometer giving you this measurement.Total Lung Capacity = vital capacity + reserve volume = approximately 6 L.Any less than the normal volume will cause a loss of gas exchange. It may not seem much at first but if it progresses, it can lead to the what might be called suffocation. You can not get enough oxygen in the lungs for cell metabolism and it will finally lead to death.
There are multiple factors effecting oxygen carrying capacity of blood. These include:Iron levels,The number of red blood cells (the less there are the less oxygen carrying capacity).Diseases which may damage either the red blood cells or the haemoglobin which is the component which actually carries the oxygen.Hydration level of the person, the less water, the less blood volume the less capacity to carry oxygen!!
less gas exchange damages the lungs because the less Co2 (carbon dioxide) that is let out dameges the body in more ways than explainalbe
vital capacity in females is less because of the structural difference in the chest cavity for example the size of the lungs is smaller in females and the size of rib cage is also less in them. the metabolic rate is also less in females that s why the vital capacity in females is less.
The Lewis structure of a cation with a 1+ charge would have one less electron compared to the Lewis structure of the neutral species. This is because when an atom loses an electron to form a cation, its overall charge becomes more positive due to the loss of a negative charge (electron).
A hydrogen atom carries a neutral charge. (The number of protons and electrons are balanced.)A hydrogen cation is an ion so it carries a charge, and it's a positive charge because it's a cation. (There is one less electron, which makes the element a cation.)
