Copper has a specific heat of 0.382 J g-1 degrees Celsius -1. The temperature of an unknown mass of copper increases by 4.50 degrees Celsius when it absorbs 3.97 J of heat. What is the mass of copper?© BrainMass Inc. brainmass.com October 24, 2018, 5:15 pm ad1c9bdddf
The easiest way to approach this is as a direct proportionality. Thus it reduces to an elementary algebra problem. Since our constant (specific heat) has ...
Shows how to calculate specific heat of a mass of copper as a mathematical proportionality.
Properties of your chosen element
you are going to investigate an element of your choice. Once you have chosen and researched your element, you will create a presentation using powerpoint or Word document . Your presentation should include the following information:
• the element's name and the origin of its name
• the element's symbol, atomic number, and atomic mass
• the group/section where the element is found on the periodic table
• the element's electron configuration and number of valence electrons.
• At least eight other researched physical and chemical properties of the element should be mentioned. These properties may include but are not limited to:
o ability to conduct electricity
o state at room temperature
o common compounds it forms
o boiling point
o melting point
o potential hazards of the elements and/or its compounds
• when the element was discovered and/or created, if this information is known
• common historical and/or modern uses for this element
• citations of the resources (web sites, books, encyclopedias, etc.) that you used for your research
