the chemistry of water

Chemical equations of water and what they represent

The chemical equation for water is H2O or HOH. Water consists of 2 hydrogen's and 1 oxygen. The atoms are joined together by covalent bonding, that means that they share electrons. Water is the most abundant molecule on the earth. Approximately 70% of the earths surface is water.

Natural processes of water

As the sun heats the surface or a lake, pond, or ocean, the water changes from a liquid to water vapor. The water vapor then rises into the atmosphere and is moved around by winds. The clouds in the sky are big masses of water vapor condensing back into liquid water as well as other things. When there is enough water that it can't be held anymore that creates rainfall. If the air is cold enough the water can freeze.

When the water falls out of the atmosphere it lands on land or in water. The soil on land absorbs the water for plants. Some of the water however is kept as groundwater which can be absorbed by an Aquifer. Aquifers in the ground store the water that has gone through sand, other rocks, or dirt. When the water is absorbed by an aquifer it filters out all of the bad things that may have stuck with the water through its journey. Water that falls into the lakes, rivers, and oceans can now restart the cycle.

Anthropogenic processes in water

An Anthropogenic process is pollution or a pollutant that originates in human activity. Water pollution usually is caused by humans. There are two types of sources of water pollution, point and non-point sources. Point sources release pollutants directly from a pipeline or sewer into a lake, pond, or many other types of water. An example of a point source would be a manufacturing plant dumping waste into a nearby lake or pond. Other examples are factories, sewage treatment plants, underground mines, oil wells, and oil tankers. Some company's or plants make their own pond for the use of dumping.

A non-point source is a type of source that is unknown or untraceable. Non-point pollution is very hard to control because of the fact that you are not able to trace exactly where it comes from. There are many sources that contribute to non-point pollution, one of them being traffic. Traffic is so abundant and so hard to prevent. Simply because of the fact that there is so much traffic and only a limited amount of ways to help control pollution from cars. Other sources of non-point pollution are acid deposition from the air, pollutants that are spread through rivers and pollutants that enter water through groundwater.

The good and bad of water

Water on average makes up between 60 and 70 percent of your body weight. Your body systems all rely on water to properly function. Water carries nutrients to your cells. Water also flushes toxins out of your vital organs. If you don't have enough water in your system it can lead to dehydration. Dehydration occurs when you don't have enough water in your body to perform normal functions. Dehydration makes you tired and can drain your energy very quickly.

Drinking water can have many benefits for a persons health. Water is a great substitute for the sugary unhealthy drinks that people drink daily. Water keeps you more hydrated than a sugary soda and is also healthier for you. Drinking a healthy amount of water can reduce a persons risk of having a heart attack, keep a person energized, or even help cure someones headache. If you are exercising in any way you need to drink more water than normal. If you do not have enough water while exercising you will have no energy and may even faint.

Water is one of the most important things on this planet. Without water we would not be able to live. water is used for more than just drinking though, we use water in our houses, to grow food, in farming, industries, and even to produce energy. In our houses we use water to cook food, bathe, wash dishes, toilets, and just water to drink. Farmers who grow our crops for us use water by bringing it into the fields through canals and irrigation systems. Hydroelectric dams use water to produce energy helping us not pollute the earth so much as well as less expensive energy. Water is used in many other ways besides our homes, farming, and energy.

The bad things about water include contaminated water, toxins, and lack of clean water people are drinking. According to the U.S. Department of Public Health, 85% of the water in the United States is dangerously contaminated. 80% of the worlds cases of disease are traceable to unclean water. There are currently 12,000 toxic chemicals in water systems. Over 23 million Americans are presently drinking polluted water.
