Physical Science- Chem 1010 intro to Chemistry

The class is designed to obtain a basic understanding of chemistry that will focus on basic concepts in modern chemistry in developing problem-solving skills. while I am in this class, I am hopeful I can learn and understand the fundamentals of chemistry so I can feel confortable in moving forward in my future chemistry classes.

 Assignments

In class, everyone was given an element to Identify the information for each chapters of what we learned in class. I was given the element of Copper and the following information is what I have found out:

 

Chapter 4

  • Atomic symbol: CU
  • Atomic number: 29
  • Atomic mass: 64
  • X-diagram: 29 protons and 35 Neutrons
  • Elements group: Transition Metals/section 11
  • physical state at room tempature: Solid
  • Density at room tempature: 8.96 g/cm3
  • Color: Orange-Red
  • Metal or non-metal: Metal

Chapter 5 

  • Name of cation and anion: Copper I (Cuperous)
  •                                               Copper II (Cupric) 
  • Type of binary compound: Type 2/ Two diffren Cation and Oxidization states
  • Polyatomatic anions: Copper (I) Hydroxide CuOH, Copper (II) Hydroxide Cu(OH)2, Copper (I) Chlorate CuClO3, Copper (II) Chlorate Cu(ClO)2, Copper (I) Acetate CuC2H3O2, Copper (II) Acetate Cu(C2H3O2)2, Copper (I) Nitrate CuNO3, Copper (II) Nitrate Cu(NO3)2, Copper (I) Carbonate Cu2CO3, Copper (II) Carbonate CuCO3, Copper (I) Sulfate Cu2SO4, Copper (II) Sulfate CuSO4, Copper (I) Phosphate Cu3PO4, Copper (II) Phosphate Cu3(PO4)2

  • Oxidation state: 1+, 2+
     
     

Chapter 6

2Cu (s) + O2 (aq) = 2CuO (s)

 

Chapter 7

Cu(NO3)3 (aq) + NaCl (aq) = Na(NO3)3 (s) + CuCl (aq)

 

 Chapter 8

  • molar mass: 63.5
  • 63.5 mol * 1.0*10 25/1 mol = 6.35*10 26 g
  • 6.35 * 10 26g * 1cm3/65 =9.8*10 24 cm3

 

 Chapter 9

  • 2Cu + O2 = 2CuO
  • Cu= 100g Cu * 1 mol Cu/128g Cu = 0.78 mol Cu
  • 0.78 mol O2 * 16g O2/1 mol O2 = 12.48 g O2
  • Oxygen=Limiting

 

Chapter 12

                                       Electronegativity: 1.90

                                     Type of bond:  Ionic Bond

Chapter 19

Isotopes: Cu-63 & Cu-65 

Type of decay: Beta

64/29 Cu + 0/-1 e = 64/28 Ni

 

 Course Reflection

Now that it is towards the end of the semester: I can now read a periodic table on knowing the Chemical Symbol; Mass Number; Atomic Number; and Electronegativity, convert measurements and figure out how many moles is in a certain measurement of element, figure out the chemical reaction in aqueous solutions and balance it out, and identify the type of bond and decay of the element. I think this has been a helpful class and it will help me move forward to my more advanced chemistry class.
