Solvent and Solubility Introduction: In this experiment, several organic chemicals were tested for their solubility. These organic chemicals are acetone, ethanol, ethyl acetate, ethyl ether, hexane and methanol. They were put to test with potassium bromide (KBr), an ionic compound, benzoic ac...

Electron Pair Repulsion Theory: The electron pair repulsion theory states that the electron pairs in the valence energy level of an atom repel each other, and therefore are arranged as far apart as possible. For example, H2O: Due to this theory, different molecules with different...

Water 's presence in the Living World Water is essential in the living world, it is the main component in glacier, sea and present predominantly in living cells. Water is used for drinking, washing and irrigating crops and watering livestock. It also acts as a thermal regulator by smoothing o...

Ozone and Its Problems: Some of the world's brightest scientists have come up with the theory, that the human race is slowly depleting the ozone layer. By depleting the ozone layer the planet becomes warmer. Ozone depletion has been one of the most discussed issues in the past twenty years, wh...

Friends of the Earth say that "up to 24,000 people die every year as a result of air pollution." That is not much of a surprise when there are now around 500 million cars polluting the planet. The problem is that we can't live without cars, because they are part of our daily lives. But, from the ...

Mars has been a place NASA and other organizations have wanted to conquer after the Apollo missions. It has been several decades since anyone has sent anything to Mars. Lately though Mars has been the main focus to space engineers and scientists. This is because in 1989 President George Bush cal...

Water is the most available compound on earth and is essential to life itself, without water, Earth would not exist. Water is a major component of cells, typically forming between 70 and 95% of the mass of the cell. This means that we are made approximately 80% water by mass, with some soft bodied c...

My name is Bon, and I am a carbon atom. I am a non-metal element, living in the north eastern region of the periodic table, in Period 2, Group IV, which means I have two occupied shells and contain 4 electrons in my valance shell. I am universally renowned from my chemical symbol of C, and distingui...

Water is Essential for Life Water is the most important substance in our evolution and our daily lives. Without water, life as we know it would not have been possible. It's important to understand and examine the water molecule in order to ascertain how it brought about Earth's thriving ecosyste...

Purpose: The purpose of this lab was to use our techniques that we have learned so far in lab in order to synthesize acetaminophen from p-aminophenol and acetic anhydride. This lab was also intended to teach us how to isolate and recrystallize our compound in order to get rid of as much impurities a...

We live our days on earth carefree and happy, but for some that life is taken away in a single look in the mirror, or a visit to the doctor. In that one instant, they find out that their life could be changed forever; some find out their life is closer to the end then they thought. Skin cancer can b...

QUESTION 1: Technology owes Ecology an Apology. Indeed, in my opinion, technology does owe ecology an apology. This is because ecological imbalances were as a result of the Industrial revolution, which could be said to be the beginning of the non-ending technological advancement cycle. D...

Chlorofluorocarbons (CFC) is a molecule made of chlorine, fluorine and carbon atoms. It¡s a stable but dangerous molecule. It used to be used in refrigerators, freezers and aerosol cans. It had been used as coolant in refrigerator propellants in aerosol sprays. It has been used as early as the 19...

Thermal Pollution: A Global Problem Recently, as a result of the increased energy demand, we've allowed our planet to begin overheating. With the introduction of more and more heated water into our lakes and rivers, and Carbon Dioxide into the atmosphere we've managed to raise the temperature of ...

CRUDE OIL Crude oils are unprocessed oils mined straight from the oil source. Crude oils are such a useful starting point for so many different substances because they contain hydrocarbons. Crayons, plastics, heating oil, jet fuel, kerosene, synthetic fibres and tires are all originally made from...

Heat from our sun passes through the atmosphere, causing it to warm up. Most of it warms the earth's surface. While the earth is warming up, it sends out this heat in the form of radiation. The atmosphere traps part of the heat, and the rest escapes into space. This effect that takes place on earth...
