Answer:
I think C
Explanation:
kinetic energy formula: 1/2mv^2
1/2(620kg)(9m/s)^2
1/2(620kg)(81m/s)
1/2(50220)
KE = 25110 J
D -
You basically keep varying the coefficient so until the number of atoms for each element is equal. I started with iron to show how you might have to change coefficients but it would be more efficient and quicker to start with oxygen since it changes the value or iron required.
