t 2 Answer the following questions in the space provided 1 B

t 2: Answer the following questions in the space provided. 1 Balance the following equations. (6 points) 2. Calculate the number of atoms in 66.0 g of Cu.(3 points) 3. For an element nickel, a. write an electronic configuration (3 points) b. write a condensed electronic configuration (3 points) c. draw an orbital diagram for nickel (3 points) d. write a valid set of 4 quantum numbers to describe one of the outer electrons (4 points)

Solution

Question 1

Balanced equation:
Zn(OH)₂ + 2 HNO₃ ====> Zn(NO₃)₂ + 2 H₂O
Reaction type: double replacement

Balanced equation:
C₅H₆O + 6 O₂ ====> 5 CO₂ + 3 H₂O
Reaction type: combustion

Question 2

Molar mass of Copper =   63.546 gm/mol

Number of Copper atoms = 66 x 6.023 x 10²³ / 63.546 = 6.255 x 10²³ atoms
