The pH is a measure of acidity or alkalinity of a solution. The pH indicates the concentration of hydronium ions [H3O +] present in certain substances. The acronym stands for 'power of hydrogen'.
When is acid have more hydronium
If is less than 7 is more acid if its more than 7 is basic and 7 is neutral.
Ion a particle an atom or groups of atoms that carries a positivesor negative charge
Every molecule of water contains two hydrogen atoms H linked to one oxygen atom O the formula for water is h2o.
The water ca contains mere than hydrogen and oxygen it contains too ions one of each is the hydroniumion (H3O+) that is formed by the interaction of a hydrogen ion with a water molecule this ion is electrically unbalanced .
Pure water was consider neutral and has aph value in 7 means that have the same concentration in hydronium ions and hydroxyl ions. If tis basic hace more hydroxyl ions and more acid if it have more hydronium ions.
When we breath contains carbone dioxide and the carbon dioxide is acidic.
The acid rain is because a substance added to the water produces more hydronium ions. And when the water evaporates when the days are more hot itevaporates so fast and the days when is more cold evaporates more slow.
The nitrogen is needed by all living things plants need it for the growth of stems and leave animals need nitrogen in the form of proteins in order to build and repair body parts. Nitrogen is also the major component of air 78 only a small number of plants can obtain their supply of nitrogen directly from air. acidic rain isharmful to the environment in general and to plant life if it too acid.
Phosphorus is found in the waste products of industrial plants human sewage animal manure from farmlands and in some fertilizers excess phosphorus can enter lake water this occurs when industrial plants dump wastes directly into a lake.
The nitrogen cycle is not combined with any other component or element but mostplants and animals cannot use free nitrogen. Any process that combines nitrogen in the air with other elements is called nitrogen fixation. it can now be utilized by a variety of living organism including humans acid rain contains nitrogen in the form of nitric acid.
When nitrogen fixation takes place (plants fix nitrogen from the air forming nitrogen containing compounds.
When animals eat plantsusing the nitrogen compounds in the plants as a source of nitrogen.
When animals die. Descomposers eat their remains and produces ammonia ammonia enters the soil and the air plants utilize this ammonia and the cycle continues.
The lake succession is the process where the different species of plant life in an ecosystem cange over time this process also affects the animal life in the ecosystemin a lake succession happens in four stages.
Cuando los animales se mueren se acumulan en el fondo.
Erosion is the movement of weathered rock and soil from one place to another erosion is caused by factors such as gravity running water ice wind and human activity.
Weathering is the breaking down of rocks due to exposure to the atmosphere weather and climate is an important process togetherwith erosion the process of weathering affects the surface of earth over time entire mountain ranges will disappear.
Soil is a mixture of weathered rocks and organic matter without soil nothing will grow the rock material in soilis made up of three parts sand clay and silt.
Silt is any earthy material composed of fine paricles such as soil or sand suspended in water or deposited by water.Pests are plants or animals that are considered to be harmful (nocivas) to human health or economy.
Pesticide a chemical substance used for the control or elimination of pests.
Biomagnifications a process in which the concentration of a pesticide increases as it travels higher and higher in a food chain.
Cultural eutrophication a speeding up of the natural aging process of lakes caused by human...
