Question 1

Why Do We Burn Things For Energy

Answer 1

When electron bonds are broken (burned) they release energy

Question 2

What Makes Oil So Good To Burn

Answer 2

Most Efficiency For Lowest Weight
Efficiency = most hydrogen per carbon

Question 3

What Happens When There Is An Oil Spill

Answer 3

*Oil is less dense than water so floats across the surface (diffusion) making cleaning it hard
*Because of its toxicity and weight it slows down, sinks and poisons sea creatures
*When it sinks it is congealed on the seafloor and combines with the sand making it take a long time to be removed
*i wish i could put these into mini flashcards because it is way too long
