+→ your old bike left out in the rain starts to rust. what coefficients fill in the blanks to balance the equation? a) 1,2,3 b) 2,3,1 c) 2,3,2 d) 4,3,2

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.

We can infer that star y is closer but other factors must be considered include the heat of the star, the mass, and the brightness of the star. even though star x seems dimmer it may just be less bright or contains less heat.
