One property of water that makes life possible on earth is its solid state‚ (frozen).Water is less dense as a solid than it is as a liquid‚ which enables ice to float. When its temperature falls below 4 degrees Celsius‚ the molecules slow down to a point where they are not moving fast enough in order to break the hydrogen bonds‚ therefore making the bonds more stable. The bonds then are farther apart‚ making the solid less dense. Water is one of the few molecules that has this property‚ allowing

What Factors Affect Chemical Equilibrium? Introduction: In investigation 14‚ “What Factors Affect Chemical Equilibrium?”‚ the purpose was to find out which reagents caused a change in the chemical equilibrium. A deep red color was formed when Iron Nitrate [Fe(NO3)3 (aq)] was mixed with water and Ammonium Thiocyanate [NH4NCS (aq)]. The product of these two reactants was Iron Thiocyanate(FeNCS). After different trials of mixing the given reagents

Cultural‚ Biological‚ Physical and Chemical An entirely different perspective is brought into focus as we consider some of the environmental hazards that accompany industrial growth and intensive agriculture. Some of the most dangerous hazards in this world are the outcome of purely voluntary behavior --- in particular‚ smoking tobacco and engaging in risky sexual activity. We will look at four classes of environmental hazards: Cultural‚ Biological‚ Physical and Chemical (Wright & Boorse‚ 2011)
