Since carbon has 4 valence electrons, a total of 4 bonds will be drawn withing methane, one between each H and the center C
Hope this helps
Answer:
Volume of water displaced = 450 - 375 = 75 ml
Vr = volume of rock = 75 ml
Wr = 9.22 - 7.60 = 1.62 N weight of 75 ml of rock
Density of rock = 1.62 N / 75 ml = .0216 N / ml
Density of water = 1000 g / 1000 ml = 9.8 N / 1000 ml = .0098 N / ml
Density of rock / density of water = .0216 / .0098 = 2.20
B) Copper atoms have a loosely held free electron in their outer shell that is able to move freely to other atoms.
