Water is a chemical compound with the chemical formula H2O. A water molecule contains one oxygen and two hydrogen atoms 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 (water vapor or steam). Water also exists in a liquid crystal state near hydrophilic surfaces. Water is considered a purifier in most religions. Major faiths that incorporate ritual washing (ablution) include Christianity

were derived from his experiments‚ proved that obedience is one of the basic elements in the structure of social life. The proximately of the victim‚ responsibility for the actions‚ and perceived legitimate authority figures will greatly determine how far an individual will go to fully comply. Obedience‚ which is one of many social influences in our life’s‚ results in a change in behavior when a direct command is given by a high authority. The main focus in Milgram’s experiment was to specify what

Study was performed to determine what factors influenced people to submit to authority and to what extent people conform an order against their conscience despite knowing it causes distress and harm to another person.

Introduction The purpose of the experiment was to determine the melting points of compounds using a Mel-Temp device. The melting point of naphthalene‚ urea‚ and sulfanilamide are found. This is then followed by the measuring of an unknown compound‚ and an impure sample (a small amount of naphthalene mixed with the unknown). Experiment In the lab‚ the height of the chemical in the capillary was set to 2-3 mm thickness. The voltage at the Mel-Temp started at a low setting of 1.5-2. The heat was

Title Antimicrobial properties in different type of plants. Introduction A substance that kills or prevents the growth of microorganisms for example bacteria‚ fungi or protozoans is called an antimicrobial. This substance has 2 major roles which are to either kill microbes (microbiocidal) or prevent the growth of microbes (microbiostatic). Disinfectants are antimicrobial substances used on non-living objects outside the body. This substance included antibiotics‚ antifungals‚ antiprotozoals and

Purpose This experiment shows how different concentrations of acids and bases in a solution affect its pH level. When acids and bases are combined in a solution‚ they neutralize each other. This means that depending on the concentration of both acids and bases in a solution‚ the pH will vary. A neutral pH level is 7; anything below that level is known as an acidic solution‚ while anything above is known as a basic solution. To find out the pH‚ the solutions will be diluted and tested with different
