1.) How do metal elements combine to form metallic bonding compounds? What is the ionic chemistry that happens when these elements form their metallic compunds? For example, Cu+ and Sn+ combined together form the metalloid called Bronze.
2.) How many Joules of energy are needed to change 10.0 grams of solid H20 to liquid H20? (Heat of fusion = 335 J/g). Which answer is correct and why?
A.) 10.0 grams of H20(s) x 335J / 1 gram of H20 (s) = 3,350J
B.) 10.0 grams of H20(s) x 335J / 18.02 g of H20 (s) = 186J
3.) What is the Oxidation Number
A. C02 - for Carbon?
B. H2S04 - for Sulfur?
C. MnS04 - for managanese?
D. C204^2- for each element?
E. KNO3 - for each element?
F. SO4^2- for each elemtn?
- Thanks so much for all who responded!
