1. Silicon is in the same group and also has 4 valence electrons.
2. covalent
3. 1
4. Wood
6. 1s22s22p2
7. Covalent
Those questions were somewhat simple. Questions #5 and #8 I'm not certain of and if you have any kind of textbook or course material, it'd be beneficial to look at it. I hope you were able to figure out the answer to Question #4 was "Wood", otherwise your teacher must be slacking :P. I'll try to figure out the answers to #5 and #8 and let you know what I figured out.
Cytosine guanine thymine adenine
Answer:
371.12 minutes would it take to completely burn off the meal.
Explanation:
Amount of fat in the food = 58.0 g
The respective fuel values for fat = 38 kJ/g
Amount of protein = 39.0 g
The respective fuel values for protein = 17 kJ/g
Amount of carbohydrates in the food = 177 g
The respective fuel values for carbohydrates = 17 kJ/g
Total energy derived from the meal = Q

Q = 5876 kJ
Energy used while jogging for 1 hour = 950.0 kJ
Energy used while jogging for 60 minutes = 950.0 kJ
Let the time require to burn 5876 kJ of energy be t.
So, 

371.12 minutes would it take to completely burn off the meal.
