 * Notes on the Substances in our Chemistry Lab:**

Bromothymol Blue Solution: Chemical Formula: C27H28Br2O5S

Calcium chloride:  Chemical Formula: CaCl2 ionic compound highly soluble in water can irritate skin, lungs and nose Sodium Bicarbonate: -chemical compound NaHCO3 -white, solid, crystalline -slight alkalikne taste (washing soda is called sodium carbonate) -disolved in many mineral springs -commonly called baking soda, bread soda, cooking soda -non-flammable -can treat acid indigestion, heartburn -effective in cleaning and scrubbing -used in BC dry chemical fire extinguishers


 * Interview with an Electron:**

1. Metallic Bond ~ There's an attraction of positive ions and free-moving electrons ~ Substances are good conductors of electric current

2. Ionic Bond ~ Compounds have a crystal-lattice structure ~ There's a transfer of electrons ~ A metal reacts with a nonmetal 3. Covalent Bond ~ There's an attraction between nuclei and shared electrons ~ Two or more nonmetals are involved


 * Three sports that we play and how they relate to bonds: **

Swimming:It is covalent because the water that makes up the pool is a covalent bond. Also the caps are made of silcon and the substance silcon is covalent. Softball: It is metallic because the bat is metal and can conduct electric current. Horseback Riding: It is ionic because the horseshoe transfers electrons to the horse's foot combining to form the shoe for the hooves.
