Water is a chemical compound with the chemical formula H 2O. A water molecule contains one oxygen and two hydrogen atoms that are connected by covalent bonds. Water is a liquid at standard ambient temperature and pressure‚ but it often co-exists on Earth with its solid state‚ ice‚ and gaseous state‚ steam (water vapor). Water covers 71% of the Earth’s surface.[1] It is vital for all known forms of life. On Earth‚ 96.5% of the planet’s water is found in seas and oceans‚ 1.7% in groundwater‚ 1

If you take a look at the paintings‚ you will see that they are abstract. In fact‚ they are painted in a style that is sometimes referred to as "Abstract Expressionism". Many people have trouble understanding and appreciating this type of art. The purpose of this essay is to explain how‚ over time‚ art has evolved to become more and more abstract‚ and why this is important. My intention is to explain the goals of abstract art‚ and to help you learn how to enjoy it. To begin‚ I’d like to introduce

Practical 3 Title: Effect of dissolved Carbon Dioxide on the pH of Water Aim: To investigate the effect of dissolved carbon dioxide on the pH of water. Hypothesis: The dissolved carbon dioxide will cause the water to turn acid‚ lowering the pH when carbon dioxide dissolves in water in which it forms carbonic acid (H2CO3). Materials: Straws‚ distilled water‚ safety glasses‚ pH probe‚ computer‚ universal indicator‚ gloves‚ lab coats‚ measuring cylinder‚ data logger‚ printer

Introduction: Temperature - Is a measure of the motion of particles‚ increasing the temperature will cause the particles to move faster because the reactant particles have more thermal energy from the heat. When particles move faster‚ more frequent collisions will occur and the collisions are more violent. This should increase the reaction rate. This will result in the particles colliding more frequently and increasing the speed of the reaction. Also when they have more energy there will be more

Every winter road salt is used on sidewalks‚ roads‚ and highways to melt snow and ice. These are to prevent human activates from turning into accidents. When the snow melts the road salt gets dissolved into the melted ice and snow and becomes a formula. This formula sinks into the land (soil mostly) and kills vegetation. The purpose for this exit project experiment is to find out what are the affects of road salt on plants. The reason for doing this lab is to find out what a

Since 1980s‚ the coagulase-negative staphylococci (CoNS) ) is a primary consideration in the rise of surgical site infections. The Staphylococcus epidermidis is the predominant CoNS on human skin and methicillin-resistant are the isolates of CoNS that showed an increasing amount where perioperative prophylaxis are not effective‚ methicillin-resistant Staphylococcus epidermidis (MRSE) is then used in the study. The aim of the present investigation was to evaluate staff of the operating department

The effect of enzyme concentration‚ substrate concentration‚ pH‚ and temperature on the enzyme catalase. Introduction: Enzymes are biological catalysts; proteins and RNA. They are required for most biological reactions and they are highly specific. Each enzyme has an active site. The active site is the spot on the enzyme where a substrate fits in. Substrates binds with enzymes through the active site. Enzymes‚ being highly specific‚ only fit with one certain substrate. Enzymes and substrates
