    Mass Volume And Density Lab

    1993 words - 8 pages

    Student Name Teacher Class Date Mass, Volume, and Density II. Objectives: Upon completion of the lab, the student will be able to identify metals using density and understand the relationships between mass, volume, and density. III. Theory: Using the mass and the volume of an object, the student will be able to identify a metal by finding the metals density. A balance can measure mass, which is best, defined as the amount of matter in a sample. In order to measure an objects volume, the student will have to use water displacement for irregular metals and various formulas to find th

    Chemistry Of Copper

    2240 words - 9 pages

    CHEMISTRY OF COPPER Introduction Copper is a chemical element with the symbol Cu and atomic number 29. It is a ductilemetal with very high thermal and electrical conductivity. Pure copper is soft and malleable; an exposed surface has a reddish-orange tarnish. It is used as a conductor of heat and electricity, a building material, and a constituent of various metal alloys. Copper was the first metal mined and crafted by man, and has been the most important one in the oldest times of history, because it was available in great quantities and was initially extractable almost at the surface

    Single Replacement Reaction between Iron filings and Copper Sulfate In this lab, unlike the previous labs, we had to take safety precautions and procedures in order to not end, well, dead or disable for life. For example, we had to use safety goggles and laboratory aprons at all times in the lab and wash our hands at the end of the lab. We had to take these precautions in order to protect ourselves as copper sulfate is able to make a person blind if it falls on someone’s eyes and be poisonous if eaten or inhaled. A single replacement reaction is a chemical reaction in which an element repla

    Density of Pennies Lab Introduction “The one cent coin, commonly known as the penny, was the first currency of any type authorized by the United States.” (www.pennies.org, pg.1)The first penny was made in 1787, composed of pure copper. They continued to produce pure copper pennies until 1837 when they switched to bronze. In 1857 they began using copper and nickel. The composition of a penny changed twice more before 1982. The pre-1983 penny was made of an alloy of copper and zinc. An alloy is “a substance that has metal characteristics and consists of two or more different elements”. (Coord
